Since they're coming from Italy I think Mac is trying to say that the shipping fee is $40 and up. Cheapest radelli rim they on that site is 50 euros, so it's an investment.

If I were looking at another supplier, what's the width on the Stornello rims? I haven't yet cut my tires off to investigate.

    *Please Help Me Better Understand My Airone.*
     
    I have a 1955 Moto Guzzi airone militaire. I have the owner's manual but do
    not speak Italian. I have been working on and riding my bike for a couple
    of years (including two Moto-Giro USA competitions) but still have many
    questions about how best to maintain it.
     
    1. Oil recommendations? I am told straight weight 30 or 40 mineral oil.
    Does it really matter if is it 30 or 40 or a 10-40 weight?
     
    2. To change the oil I drain the oil tank under the gas tank. Is this
    sufficient or do other recommend draining the oil lines too?
     
    3. I add the fresh oil to the oil tank filler. I have been using 10-30 or
    10-40 mineral oil and it seems to be OK.
     
    4. I do open the small drain bolt almost behind the exposed flywheel.
     
    5. Please explain to me the two small filler bolts above the transmission,
    just aft of the flywheel. Do I add oil to either or both of these? I
    believe I was told one or both of these are for cleaning the clutch plates.
    How would this work - details please.
     
    6. Recommendations on lubricating the front forks? Does lubing it through
    the grease fittings suffice?
     
    7. Anything else I need to be aware of (besides the obvious items like
    greased and adjusted drive chain, tire pressure, etc).
     
    Thanks,

    Oil threads are full of opinions. I think 30 is perhaps too thin. 40
    or even 50. There is no oil filter as such. Multi-grade oils have
    detergents to keep impurities in suspension for filtration. I think you
    want to stick with single grad.
     
    > 2. To change the oil I drain the oil tank under the gas tank. Is this
    > sufficient or do other recommend draining the oil lines too?
     
    If it is a running bike, then siphoning out the tank is probably
    adequate. The scavenge pump keeps oil out of the sump. If it sits a
    long time there might be oil in the sump. If necessary to drain the
    sump, just remove the short, 90-degree oil line below and behind the oil
    pump. You'd have to be REALLY anal to remove and blow out all the oil
    lines. The risk to compression threads is way more than the risk of a
    small percentage of old oil. Oil is cheap in comparison to parts and
    labor. If you are concerned, just do it more frequently and the
    contamination from oil in the lines becomes diluted and inconsequential.
     
    > 4. I do open the small drain bolt almost behind the exposed

    That is only for draining the clutch chamber. Some oil gets out here
    and there is no way for it to get back into the motor. Eventually it
    will leak from the crankshaft hole in the left cover. Time to drain and
    clean.

    One hole is for adding mineral spirits to wash off the clutch parts.
    The other is merely an access cap for the crankcase breather. The
    breather consists of a steel ball bearing. Under pressure, the ball
    lifts and relieves. Gravity drops it back down. If you pull its cap
    you will likely see a very shiny 'ding' in the middle of the cap to show
    where the ball is occasionally striking it. See the further tutorial below.
     
    > 6. Recommendations on lubricating the front forks? Does lubing it
    > through the grease fittings suffice?
     
    Go easy on the grease. Use a heavy formula but not much of it. It
    eventually will degrade and leak down the stanchions. There is also
    internal oil but that is for damping, not lubrication. Unless you have
    tipped the bike upside down, the damping oil is still in there.
     
    > 7. Anything else I need to be aware of (besides the obvious items
    > like greased and adjusted drive chain, tire pressure, etc).
     
    The original design used a crossing passage from the clutch chamber back
    over to the chain. Mist created an automatic oiler. Now that quality
    sprays are available, most consider tapping and blocking that passage
    hole to reduce chain mess.
     
     
    BUZZ, here is a pictorial tutorial I did several years back. This is
    for SuperAlce. Some of the parts shape and orientation will be slightly
    different, but the engineering design idea is consistent among the
    models. The pictures are still active.
     
    ----------------------------------------------------------------
    Several people are currently experiencing noisy gear change action and
    poor clutch performance on cold starts. Time for a refresher on the
    clutch design and the required periodic method of bathing the parts.
     
    The Guzzi-Single clutch is composed of a stacked sandwich of 5 steel and
    5 bronze plates. The steel plates are connected in their center to the
    clutch fixed body hub on the primary shaft of the transmission. The
    bronze plates are connected at their perimeter to the gear-like outer
    body basket. There may be one or two friction material rings installed
    at the base of this stack as well. The outer body basket may run on a
    continuous core bushing or it may have a packet of loose rollers. All
    of these options depend on which model and year you have, but the
    multi-plate design and basic operation are all the same.
     
    Here are pictures of a used plate stack and a fresh stack already
    installed into my SuperAlce.
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-719X.jpg
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-718X.jpg
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-720X.jpg
     
    When the clutch is bound by its spring, the stack of plates and all of
    the clutch components rotate as an intact, unit mass. When you pull on
    the clutch handle, the spring pressure is countered or relieved and the
    various pieces are released and allowed to move independently. In
    theory, the stacked sandwich parts should all slip smoothly over each
    otther so that the outer body remains spinning with the motor, while the
    inner body remains stationary. This allows you to remain in gear with
    the engine running.
     
    In addition to these parts, there is a small passage at the top of the
    crankcase which allows for a fine mist of air and engine oil to pass
    from the crankcase chamber to the exterior clutch chamber.
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-723X.jpg
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-724X.jpg
    (the zip tie is in place just to demonstrate the oil passage route)
     
    This mist of oil lubricates all the parts in the clutch chamber,
    including the plates, and eventually condenses into a puddle in the
    clutch chamber. It is a total loss system. There is no way for this oil
    to get back into the engine case. Eventually, this condensed puddle
    grows to the level that the bottom of the clutch parts are sitting in a
    pool of oil and any further excess starts to leak out behind the
    flywheel where the crankshaft passes through the clutch chamber. There
    is no seal for this passage. This blue tape represents the maximum
    depth of oil puddle within the clutch chamber before it will simply pour
    out the crankshaft hole.
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-722X.jpg
     
    Guzzi didn't want to waste this oil mist, so there is also a
    crossing passage which goes from the clutch chamber back to the right
    side in the vicinity of the chain drive sprocket. Some of the oil mist
    works its way out over here and drips onto the chain as an automatic
    oiler. Clever, but messy. Many of us plug that cross passage to reduce
    the mess and we then relay on modern chain sprays. You can see my plug
    here.
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-717X.jpg
     
    Warm, thin, clean oil is a very nice substance to put onto the clutch
    plates. It lubricates everything for smooth action and minimizes wear.
    However, cold, dirty oil acts more like a glue than a lubricant and
    prevents free action of the plates. The various clutch pieces all bind
    together and fail to slip as intended. It can become very noisy to
    shift gears, especially down into first gear. The noise also produces
    damage to the tips of the gear teeth. The COMPLETE CURE is to fully
    disassemble the entire clutch package and clean all the parts to new
    condition.
     
    The INTERMEDIATE MAINTENANCE solution is the BATHE the clutch parts to
    remove any oil or dirt or wear material and restore original action.
    Here is the procedure. It will be a VERY messy job so protect your
    floor and be prepared for hazardous disposals.
     
    First, at the lower rear curve of the clutch cover plate, there will be
    a small, slotted screw-plug. Remove that to drain away all of the
    condensed puddle of oil. Here is the drain plug at the lower rear of
    the clutch cover.
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-721X.jpg
     
    Flipping the cover over, you may be able to see the interior tip of this
    drain plug at the lower left.
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-722X.jpg
     
    Second, at the top of the left side crankcase you will find an engine
    breather tube which returns crankcase pressure and oil mist back to the
    oil reservoir tank. Adjacent to that breather tube is a slotted plug
    which leads directly to the clutch chamber below.
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-723X.jpg
     
    http://i157.photobucket.com/albums/t61/pehayes/superalce/MVC-724X.jpg
    (the zip tie is in place just to demonstrate the oil passage route)
     
    Third, introduce a pint of 'paint thinner' into the clutch chamber via
    the upper plug. If you put too much, it will simply run out the opening
    behind the flywheel.
     
    CAUTION: In America, paint thinner is also known
    as mineral spirits. It is a good solvent, but not particularly volatile
    or harsh to painted surfaces. In Europe however, the term 'paint
    thinner' refers to something Americans call lacquer thinner. This
    latter material is highly flammable and an instant paint remover and
    should NOT be used for this cleaning purpose. In a pinch, you can use
    gasoline. But please don't smoke while working.
     
    Fourth, push the kickstarter repeatedly. While doing so, pull on the
    clutch handle slightly so that the engine does not turn over but the
    kickstarter does go through full throw. In this way, the kickstarter
    will be rotating the inner body and steel plates, while engine
    compression will be holding back the external body and bronze plates.
    The paint thinner will remove oil, grime, and wear contaminants from the
    clutch parts and drop them into the bottom of the clutch chamber cover.
    Do this kicking and feathering for several minutes.
     
    Fifth, remove the plug at the rear lower corner of the clutch cover and
    drain away the contaminated paint thinner. Although dirty, it might be
    useful for other rough part washing tasks around your shop. Let it
    settle for a week so you can decant the liquid off of the settled sludge.
     
    Sixth, repeat steps three through five, perhaps a total of three rinse
    cycles.
     
    Seventh, clean up your mess and go for a ride. It will likely be
    several months or a year before you need to repeat this procedure
    depending on your miles driven.
     
    As a TEMPORARY AID before you have an opportunity to perform the more
    involved bathing or disassembly tasks you can assist the releasing of
    the cold clutch plates. You will generally find that shifting from
    neutral into second gear is a lot easier than shifting down into first.
    So, on a cold started motor, shift into second. Gently rev the motor
    slightly, and, while holding the hand or foot brake, feather release the
    clutch handle a few times so that you force a slippage of the plates
    several times. Do this almost to the point of stalling the motor. This
    will quickly heat the oil film which is binding the plates and the
    underlying components. You may now be able to return to idle and more
    quietly shift into first gear.

    Buzz......most of the guys use a straight wt. oil from what I've gathered.
    I use 20w50 because it's more available in my area and I'm cheap. There is
    the filter or screen inside your oil tank that screws out you may want to
    check. And you can flush the tank out better with that removed. When I
    change oil I remove all lines and drain any residual that might be left behind.
    And I go as far as to tilt the bike to the side to drain as much as I can
    from the crankcase.

    The small bolt behind the flywheel is there to drain any accumulation from
    the misting that chamber gets from the crankcase. Usually only about a
    teaspoon or so comes out if any.The manual says to wash out the clutch plates
    by putting some mineral spirits in that top hole and kick over the engine
    at the same time to wash off the plates. Then drain out that from the small
    hole behind the flywheel. The manual contradicts it's self in one breath
    says it should be a dry clutch and then says add an ounce of oil when done.
    I don't add any, I let the breather do it for me. I have only washed my
    clutch when it starts to get grabby or feels like it's slipping.

    I have yet to do a full fork service. There are fork seals so I'm only
    guessing there is fork oil of some kind. I have cleaned my concentric blocks of
    there old grease though to keep them happy. You can pull the covers off
    easy enough to check the condition of the grease.

    Other than the normal wear & tear maintenance you know about this is all I
    can think of for now. Others will chime in to fill in the blanks and or
    make corrections.

    Because it is helical cut, it is going to have to push in against the spring in
    order to move circularly within the slop. I doubt it is a factor. I don't
    know if a design spec exists.
     
    I don't know either. It's just a dog coupling and these things are not
    terribly tight in the first place. I'd think that 0.3-0.4 mm is OK in this
    application. I suppose you could Google "dog clutch backlash" or "dog
    coupling specs" and you might find something more.

    It is my view that bikes without oil filters should run with straight grade, non-detergent mineral based oil that is changed frequently. I run 30W in the winter, and 50W in the summer. When I bought my Astore with a failed big end, the cause of the failure was apparent. The sludge trap and oil ways in the crankshaft were packed solid with a material that resembled hardened clay. No oil was getting past that blockage.

    Some of my thoughts on choosing an oil…..
    I like to base things on whatever the manufacturer recommended. Reasons are simple. That is what the engine was designed for and despite what modern oil technology has come about, the engine, unless rebuilt to modern clearances and materials hasn’t changed in what it needs to survive. In 1955 I don’t believe multi-vis oils had been developed yet and as such the engines were not built to run them. Doesn’t mean you can’t run them but the advantages of a multi-vis oil had not yet been taken into account. Most likely if the manufacturer had designed the engine for straight 40w, a 10w-40 may not necessarily be good.
    On the other hand a straight 40w or 50w in an engine designed for a 20w-50 may also be detrimental. A month or two ago there was a discussion on the Ducati Bevelheads list where I know some of you also reside at. A member posted something about how a heavier grade of oil than what is recommended could actually cause ball and roller bearings to skid. Much like how a boat has to push its way through the water a ball or roller bearing has to push through oil. It’s not hard to visualize how too thick of an oil will try to keep the bearing from rolling.

    Wonderful info. After reading through this I now have a MUCH greater
    understanding of the oiling and clutch operation. And I can stop trying to
    fill the clutch chamber through the small top filler :-)
     
    No wonder I was getting so much oil out of the small drain behind the
    flywheel. I plan to try Patrick's method of cleaning the clutch plates with
    American paint thinner. It might help the shifting smooth out.
     
    Thanks to all.
     
    This modern Moto Guzzi sure is different in design to the old Harleys and

    Just a short note on oil.
    I tend to use either Silkolene Donnington straight 40 non-detergent or Morris Golden Film 40 Classic but both seem to only be available in UK/EU.
    .
    The rationale for non or low detergent oil is nicely written upon the Morris website:
    Golden Film Classic Oils are recommended for use in veteran, classic and vintage cars, motorcycles, commercial vehicles and tractors, where engine design and tolerances prohibit the use of modern multigrade, high additive level oils. Modern dispersant additives keep combustion chamber contamination suspended in the lubricant, allowing full flow cartridge filters to remove it. Early oil filtration, usually in the form of a mesh gauze or strainer, is not efficient enough to remove this suspended material. Golden Film Oils are low dispersant oils and allow the suspended matter to drop harmlessly into the sump. 
     
     
    Cheers
    Gordon

    Wonderful info. After reading through this I now have a MUCH greater understanding of the oiling and clutch operation. And I can stop trying to fill the clutch chamber through the small top filler :-) 
     
    No wonder I was getting so much oil out of the small drain behind the flywheel. I plan to try Patrick's method of cleaning the clutch plates with American paint thinner. It might help the shifting smooth out.
     
    Thanks to all. 
     
    This modern Moto Guzzi sure is different in design to the old Harleys and Indians I ride and wrench on most of the time.

    >Buzz......most of the guys use a straight wt. oil from what I've gathered.
    I use 20w50 because it's more available in my area and I'm cheap. There is the
    filter or screen inside your oil tank that screws out you may want to
    check. And you can flush the tank out better with that removed. When I
    change oil I remove all lines and drain any residual that might be left behind.
    And I go as far as to tilt the bike to the side to drain as much as I can
    from the crankcase.

    >The small bolt behind the flywheel is there to drain any accumulation from
    the misting that chamber gets from the crankcase.  Usually only about a
    teaspoon or so comes out if any.The manual says to wash out the clutch
    plates by putting some mineral spirits in that top hole and kick over the engine
    at the same time to wash off the plates. Then drain
    out that from the small hole behind the flywheel. The manual
    contradicts it's self in one breath says it should be a dry clutch and then says
    add an ounce of oil when done. I don't add any, I let the breather do it for
    me.  I have only washed my clutch when it starts to get grabby or
    feels like it's slipping.

    >I have yet to do a full fork service. There are fork seals so I'm only
    guessing there is fork oil of some kind. I have cleaned my concentric blocks of
    there old grease though to keep them happy. You can pull the covers off easy

    here.  Jerry Kimberlin might know.  There is quite a bit of linear
    spring force behind that gear once the flywheel is installed. Because it is
    helical cut, it is going to have to push in against the spring in order to
    move circularly within the slop.  I doubt it is a factor.  I don't
    know if a design spec exists.
     
    >>>I don't know either.  It's just a

     I'd think that 0.3-0.4 mm is OK in this application.  I suppose
    you could Google "dog clutch backlash" or "dog coupling specs" and you might
    find something more.

    Please Help Me Better Understand My Airone.
     
    I have a 1955 Moto Guzzi airone militaire. I have the owner's manual but do not speak Italian. I have been working on and riding my bike for a couple of years (including two Moto-Giro USA competitions)  but still have many questions about how best to maintain it. 
     
    1. Oil recommendations? I am told straight weight 30 or 40 mineral oil. Does it really matter if is it 30 or 40 or a 10-40 weight?
     
    2. To change the oil I drain the oil tank under the gas tank. Is this sufficient or do other recommend draining the oil lines too?
     
    3. I add the fresh oil to the oil tank filler. I have been using 10-30 or 10-40 mineral oil and it seems to be OK. 
     
    4. I do open the small drain bolt almost behind the exposed flywheel.
     
    5. Please explain to me the two small filler bolts above the transmission, just aft of the flywheel. Do I add oil to either or both of these? I believe I was told one or both of these are for cleaning the clutch plates. How would this work - details please.
     
    6. Recommendations on lubricating the front forks? Does lubing it through the grease fittings suffice? 
     
    7. Anything else I need to be aware of (besides the obvious items like greased and adjusted drive chain, tire pressure, etc).

    About fifteen years ago i bought a 30 gallon steel drum of Elf 50 W oil from a local distributor who was closing out. I am still working my way through that. I also bought some cases of semi synthetic oiI at the same time. I never thought i would get through it all, but it is now getting low. it turns out to have been a good investment.
    I believe that PureGuard still sells 5 gallon pails and I am pretty sure that I have seen a heavy duty diesel in-house brand of non-detergent motor oil at Canadian Tire. It has been some years since I have been in a Harley shop, but I recall seeing some straight grade oils on the shelf at that time. They may not carry that sort of thing anymore.

    It is my view that bikes without oil filters should run with straight grade, non-detergent mineral based oil that is changed frequently. I run 30W in the winter, and 50W in the summer. When I bought my Astore with a failed big end, the cause of the failure was apparent. The sludge trap and oil ways in the crankshaft were packed solid with a material that resembled hardened clay. No oil was getting past that blockage.

    Hi Patrick
     
    Just a quick question about the front forks for my 1958 Falcone.
    I have greased the forks but when I drive over a bump in the road it bangs
    when the forks drop down.
    It is quite a loud noise and it concerns me.
    Is there a reason for this and what is a possible solution?

    Have you checked the oil level in the hydraulic dampers?

    Aeroshell makes straight mineral oil for aircraft engines in SAE 30, 40, 50&60 weight, with alleged no additives what so ever. One wonders, but of course aircraft engines live most of their lives turning 2000-2800rpm., but still air-cooled.
    Normally if something is aviation related, you add $$$$ to the cost, but this isn't bad.
    http://www.aircraftspruce.com/catalog/eppages/aeroshelloils6.php?clickkey=9079
     
    I'll ask the guys in the maintenance shop, one of whom, has older bikes and get his take.

    I've been messing with my forks recently and had a similar problem. At the very top of the forks there's a secondary spring. it sits on a nut on that long damper bolt. According to the manual diagram you need to hold that spring between the fork caps and the nut. So if the nut is too far down there's more play and the springs bang around while you're driving.
     
    I'd be interested in other's experience, but I can't find any way to check the fluid level without getting the forks apart and out of the bike. And you will probably mess up your seals doing this so have a set handy before you start. As far as I can tell the whole idea of easily measuring the oil level with a ruler while the forks are inside the fork tubes is fiction.

    Nick,,,,,,,, most modern bikes now have a tool with a rod on it you adjust
    that measures fork oil now. Not a measured amount number listed in the
    manual like in the old says. So I used a length of wire and keep poking it in
    until I see oil on the wire. Then measure the wire. With the forks empty
    pour oil in until it hits the wire again. Keep track of the amount poured in
    for future reference.

    What I'm saying is that you can't measure the oil level without removing the damper. And you can't remove the damper without disassembling the forks, and that messes up the seals. The manual make it look like you can just unscrew the top cap and check the oil level. You can't.

    Hello Denis,
    Remove the acorn nut at the top of the fork. Unscrew the fork cap and remove it with the rebound spring. If the rebound spring has separated from the cap, that could be the source of the noise. It is held in place with an internal washer and a nut on the damper rod. You will need to make a tube spanner* to unscrew the internal plug and slowly unscrew the damper body so that the oil does not spill inside the fork leg. When the damper body is out, you can measure the oil level with a stiff wire. It should be 26-28 cm from the bottom of the sliding leg in the Astore, i am not sure if it is the same. You will need a piece of tubing to e add the oil to ensure that it does not run between the sliding leg and the fork tube. Slowly introduce the damper body to the sliding leg so the oil does not escape.
    I am going from memory here, so it might not be in order, but when you get going on this, it will become obvious.
    Regards, Alan in Vancouver
    *The tube spanner can be made by cutting some small tabs of the appropriate size and depth into the end of a pipe that fits into the fork tube, and drilling a hole at the other end for a tommy bar. if you shine a light into the fork tube, you will be able to see the pattern. I made mine from a 1-1/8" deep socket using a Dremel tool.

    Is there a source in the US for a 17" 32hole Radaelli rim for the front
    of my Stornello? Motocicli Veloce has one, but I thought I'd ask around
    before committing to the $40+ shipping fee...

    Just a short note on oil.
    I tend to use either Silkolene Donnington straight 40 non-detergent or
    Morris Golden Film 40 Classic but both seem to only be available in UK/EU.
    .
    The rationale for non or low detergent oil is nicely written upon the
    Morris website:
    Golden Film Classic Oils are recommended for use in veteran, classic and
    vintage cars, motorcycles, commercial vehicles and tractors, where engine
    design and tolerances prohibit the use of modern multigrade, high additive
    level oils. Modern dispersant additives keep combustion chamber contamination
    suspended in the lubricant, allowing full flow cartridge filters to remove
    it. Early oil filtration, usually in the form of a mesh gauze or strainer,
    is not efficient enough to remove this suspended material. Golden Film
    Oils are low dispersant oils and allow the suspended matter to drop harmlessly
    into the sump.
     
     
     
    Cheers
    Gordon

    Wonderful info. After reading through this I now have a MUCH greater
    understanding of the oiling and clutch operation. And I can stop trying to fill
    the clutch chamber through the small top filler :-)
     
     
    No wonder I was getting so much oil out of the small drain behind the
    flywheel. I plan to try Patrick's method of cleaning the clutch plates with
    American paint thinner. It might help the shifting smooth out.
     
     
    Thanks to all.
     
     
    This modern Moto Guzzi sure is different in design to the old Harleys and
    Indians I ride and wrench on most of the time.

    Please Help Me Better Understand My Airone.
     
     
     
     
    I have a 1955 Moto Guzzi airone militaire. I have the owner's manual but
    do not speak Italian. I have been working on and riding my bike for a couple
    of years (including two Moto-Giro USA competitions) but still have many
    questions about how best to maintain it.
     
     
     
     
    1. Oil recommendations? I am told straight weight 30 or 40 mineral oil.
    Does it really matter if is it 30 or 40 or a 10-40 weight?
     
     
     
     
    2. To change the oil I drain the oil tank under the gas tank. Is this
    sufficient or do other recommend draining the oil lines too?
     
     
     
     
    3. I add the fresh oil to the oil tank filler. I have been using 10-30 or
    10-40 mineral oil and it seems to be OK.
     
     
     
     
    4. I do open the small drain bolt almost behind the exposed flywheel.
     
     
     
     
    5. Please explain to me the two small filler bolts above the transmission,
    just aft of the flywheel. Do I add oil to either or both of these? I
    believe I was told one or both of these are for cleaning the clutch plates. How
    would this work - details please.
     
     
     
     
    6. Recommendations on lubricating the front forks? Does lubing it through
    the grease fittings suffice?
     
     
     
     
    7. Anything else I need to be aware of (besides the obvious items like
    greased and adjusted drive chain, tire pressure, etc).
     
     
     
    Thanks,

Stornello rims should be 2 & 1/4 x 17 inch 32 spokes.  This equates to 1.60 x 17 in modern sizes or WM1 in old money.
They are available on ebay.it  Check this search:-

 
Another option is to use 1.40 width rims off a kids Motocross bike such as a Yamaha YZ85, Kawasaki KX85 etc.  They tend to be drilled for smaller disc brake hubs and so need the spoke seats adjusting with a countersink drill bit or you end up with curved spokes (Guess how I found that one out!)  1.40 width rim will still accept a 2.75 width tyre.  A 1.60 width rim will take a 3.00 tyre.
 
For the spokes, I found Honda C50 / cub or step through spokes to be the perfect size.  I think they are 165mm from memory.

Since they're coming from Italy I think Mac is trying to say that the shipping fee is $40 and up. Cheapest radelli rim they on that site is 50 euros, so it's an investment.

If I were looking at another supplier, what's the width on the Stornello rims? I haven't yet cut my tires off to investigate.
