Having become acquainted with my Falcone on short trips and having been
confined two months, yesterday was at last time to go out and ride.
A 120 km round trip was planned with my wife on her Laverda 500. Out to
Notre Dame de Lorette, the largest French military cemetary outside Verdun
and back home via the Canadian memorial at Vimy.
The ride out was lovely. At long last I could let the Falcone off its lease
cruising very ably at 100 km/h in the sunshine.
We stopped off at Lorette where we took the photo and then headed towards
Vimy, 10 km away. I got a bit lost and pulling into a lay by by the side of
the road, there was a horrible screech. The bile was ticking over fine,
just a rumble from the engine block and the occasionnal screech.
End of ride.
I took the Laverda, rode home and came back with car and trailer.
 
The rumbling sound is there when I turn the engine over on the kickstarter,
in neutral or in gear. Clutch appears to work ok.Noise seems to be
transmission related since no tell tale knock indicating a big end gone or
a rumble from a main bearing though that would need checking.
I intend to pull the side covers off, to have a look at the clutch and
gearbox bearings and main bearings before, if I find nothing, taking the
engine out and opening it
 
I hate these "I have a noise, what could it be" questions, but are there
any known things which could be responsible for the noise? Clutch basket
nut? or bearings?

Sounds like a gearbox gearing? Never had that before!
 
Dirk Van Ussel <vanuss...@gmail.com>: May 19 12:48AM -0700

Meant bearing of course

Screeching noises usually come from dry running bearings,. Check
dynamo/magneto.

>>> I've got the feeling it's a bearing.
I hadn't thought about that magneto but surely, no ignition if a magneto
bearing packs up?
To check, I imagine I'd need to turn the mag over by hand?
 
Plus the fact that a certain roughness can be felt when turning the engine
over on the kick start.
 
I'm just hoping that it's nothing to do with me having washed out the
clutch with diesel fuel this winter and washed the oil out of the mainshaft
bearing.

My first inclination is towards the clutch.  I have seen clutch pressure
plates unscrew and scrape the cover.  Also seen them go the other way
and get so tight you can't release the clutch.  When you take off the
covers look for scrape marks on them.  Generators also howl when  their
bearings fail and the armature starts rubbing the field coil.  Bearings
are generally not a problem in Guzzis.  I've never seen one lock up to
the point where you could spin one in the crankcase.

> Thanks for checking fellas,
 
I did remove the coils on my generator, no sign of a third (red) wire.
There is also no tell tale sign that a rear brake pedal light switch was
ever mounted. The tail light has two fetsoon bulbs assuming one is for the
brake light, one black wire and one white wire but white wire was cut off
inside the tail light shell.
 
I wonder if this bike ever came with a brake light switch or a third red
wire from the coils??
 
The decal on the front fender indicates this was a domestic Italian bike,
did they require brake lights?

The only red wire I could find was from the rear/right side of the upper coil to the condenser. I have a green wire coming out of the backside of the flywheel directly to the brake light switch and nothing else attached to that wire. My bike was very original prior to the restoration but I know over the past 60yr someone had to have their fingers on the harness???

Thanks Dave
 
Does your Cardellino generator have two or three wires coming out of the
case?
 
Thanks

Three. A green one with a plastic insulation, what appears to be a yellow w/cloth insulation and a faded red one with cloth insulation

Thanks again Dave
 
So if I understand your previous response the red wire is attached to the
wire that joins the upper (ignition) coil to the condenser?
Dave Knaack <fastgu...@gmail.com>: May 18 08:49PM -0500

Yes, as best as I can see with the flywheel still in place
