YaMaha Vino @ 75 MPH!!
Chad Whitehead
I replace the exhaust with Metrakit SP, added a metrakit 70cc big bore kit,
17.5 MM carb. new rollers and gears. I used the stock airbox just drilled a
two extra 5/8 holes, one on each side of the factory inlet.
I cant say exactly what the top speed is but I passed my wife on the
freeway and she said she was going 70, I can beat about any car light to
light. This thing is a blast with a little tug on the front end you can ride
wheelies no problem.
I have a 2001 Harley Davidson and I have more fun on the stupid little
scooter, Dont ask me why I did this, I just did!! but its fun.
By the way I am 34 years old and wiegh 200 pounds, it is fun having
someone pull up to you and laugh, and then leave them in your little
scooters Dust!
Anyway I was so impressed with the upgrades I have decided to carry
them @ my car dealership so if anyone is interested in getting more bang for
their buck, E-mail me and I will let you know about it.
I also realize there are bigger scooters that go faster but I am in
Oregon where you dont need an endorsement and can license this beast as a
moped.

hmm... feasible, but even after i install the cylinder kit i woul donly do
that if i fell down a cliff.
with those tiny wheels,that would be suicidal.... any speed wobble?
good news for the power hungry child in me, but i wouldn't want to ride it
that fast without a windscreen...

that was snappy and I could ride on the Interstate if I had too.
As far as the wheels go they are way off balance and I am going to see
if I can get ther rear one balanced.

almost match an Italjet Dragster (the 50cc champion in the USA as far as
I know) in speed?
First, why...I've seen the suspension and brakes on a Vino, and the Zuma
is better prepared for those speeds, though I wouldn't suggest it. The
Dragster, on the other hand, is very well equipped (again, by USA
standards...you folks in the UK/EU have other options).
Even taking the larger wheels into account, it still doesn't
jive...60mph I'd buy, maybe even 65, but 75?
Then again, maybe I missed something...is the Vino liquid cooled? If it
is, then I might be more willing to believe it.

I might add that the stock power of a Vino is actually less than most
50cc scooters, around 5 PS. I've never seen one doing more than about
50kms/hr to be honest.

and that is with a 70 cc cyulinder kit this guy mentionned he had...

to the local Italjet dealer. Mind you, this guy has kitted everything
from his Viper, Mini-Streetbike, Go-Peds, and all his Dragsters (50,
125, 180).
He tells me the 50cc Dragster will push 75mph with kitting (and mentions
that it's finicky about airbox modifications). The 180cc, on the other
hand, will push 90+ with proper kitting.
And all "modern" scooters are "big tired" by the standards of old Elites
and Jogs, so I'm not sure what you are referring to. The Zuma has higher
sidewalls than say a Dragster, but about the same width contact area.
Heck, both the Dragster and the Zuma (among others) have more footprint
than a Helix or Elite 250!
So I still don't understand how you managed 75 mph from 70cc's when a
scooter specifically engineered for such speeds can barely manage it
with similar simple modifications.
Perhaps you can explain, since I'm a bit confused.
(In all seriousness, BTW...if you say you can, explain it. I'm still
waiting to hear back from Taffspeed...they dyno these things. I'd enjoy
know what tricks you used, they're probably applicable to other
scooters.)
As for leaving my Zuma in the dust, sure you would...I've tuned mine
more for low-end acceleration and long-term reliability...faster parts
existed, but I opted not to. Examples being expansions chambers (the
LeoVinci SP3 is more modest), torque drivers, and the more powerful DR
Racing 70cc kit (I have a Malossi). I could fit a 20mm carb. and conical
air filter as well, but that would just inhale too much fuel for my
taste.
You see, I may not be an expert, but I've had an expert helping with my
scooter for 18 months. So whatever you can pass on to the community at
large would be a boon to all of us.

The small wheels aren't a problem in themselves, as long as they are properly
balanced, after all even classic scooters with their relatively primitive
suspension achieve speeds of 100mph when racing or drag racing.

I had some radio controlled airplane 2stroke engines that would make 1.5 hp
and run at 30-40 thousand rpm all day long and trust me, they were nowhere
close to 50cc (actually 7.5cc)... but i see your point, and it's valid when
one coniders there 50cc engines are pretty cheap
the second point is more interesting to me as i'd been planning to mount a
temperature gauge on my vino.
I assume i should mount the sensor on the head somewhere? can you confirm
please?
thanks a bunch
John Smith
you'll have a hard time accelerating these 18" wheels to get them to rotate
and will loose more power to road friction.
also, you're changing the final gearing, and won't have enough torque to go
very fast. mechanically, your top speed will increase with larger wheels,
but you will need much more power.
for example, my racecar has a 290km/h theoretical top speed (transmission
limited)
of course, my engine will only allow me to do 240 because of lack of juice
(only 200 hp)
but with 24" total diameter tires, i can't make it past 200. with 20"
diameter tires, i reach that 240 without breaking a sweat.
the physics are more complicated than you make it seem....

around 12 bhp, the uprated components from the race series are well within
their design limits, so 80+ mph machines are possible with excellent
reliability." the link is

would remain unchanged as the point was about the weight of the wheels not
the size. You're right in that it would be harder to accelerate heavier
wheels but the top speed would still be the same assuming the drive ratio
didn't change. The only impediments to top speed are friction in the form of
road/tyre, bearings etc and aerodynamic friction and the power you're
putting out to counter that friction.
I'm coming from the bike racing world here and the first thing you do with a
new race bike (even a HRC GP bike) is put on light wheels of the same size.
It doesn't have any effect on top speed but increases the suspension
response (reduced unsprung mass), allows a quicker turn-in to corners (lower
polar moment of inertia) and gives better acceleratio off corners (lower
overall mass).
hope that made my thoughts clearer

measure the coolant temp and you know that will be pretty consistant but for
an AC donk the location of the probe and the design of the head will have a
huge effect on the measure temperature, I've seen some probes that measure
under the spark plug washer which would probably work, depending on the sump
size you might be better off measuring the oil temperature but it doesn't
give you all the same advantages. If you only want to know when it's up to
temp or when it's overheating oil temp will be OK but it won't cut it for
tuning and jetting by temperature (but that would be overkill for a scoot)

I expect to hear about your scooter blowing up soon here. Better check

Yes, and I just heard from Terry...he said if I give him more details,
he can evaluate the veracity, but he says with just a couple "road"
parts it seems very unlikely.
However, given your quotation above, then I can assume your mods at
least included an Expansion Chamber and an Aluminum 70cc kit, along with
roller adjustments and a bigger carb. (assuming it has a standard 14mm
carb., usually need 17.5mm on performance enhancements).
In any case, I'm assuming also "race series" components (as per the
Taffspeed quote above), along with race-series reliability (i.e.
complete teardown and parts replacements on a regular basis). This is
not unlike the Zuma and many other 50cc scooters...even a Spree can go
fast with the right parts (but do you want to?). Terry said he's raced a
Zuma that touched 80mph.
So all I ask is for you to post the parts list of your modifications. If
only for curiosity sake. Any air-cooled 50cc that will do 120km/h
(74mph) is quite impressive and sharing the parts list would help
others, including myself, do the same thing.
As for those accusing me of being jealous, hardly. Vino didn't exist in
this country, nor did the Dragster, when I bought. I've seen the Vino
and I wouldn't push it past it's stock speeds on those brakes and
shocks...too dangerous. I'd be more jealous of a Dragster owner
(especially the 180cc!) or a Runner owner (I understand they may make it
to the states), and if I really wanted to go 70mph I'd just get a Reflex
and be done with it, since you can't do 70mph on city streets and you
need 150cc to go on the freeway.
I'm not jealous, I'm just a bit confused about the numbers since
"simple" performance mods on almost *all* 50cc get about the same
speed...60-65mph (more likely 55-60mph). A 250cc Helix can barely sneak
into the 70s as I recall, for example (sure, it's heavier, but it's
250cc!).
So that's all I ask. Okay, so "I don't buy it may have been
harsh"..."don't believe it" is more polite, or "please explain how"
would have been better, and for that you have my apologies.
So let's see that parts list, "inquiring minds want to know"...

Well, I really didn't want to get into this, since all the points made
here are good ones, and on my initial reading of the originating post
I figured "No way" myself. However, after getting my Yamaha Jog, which
to the best of my knowlege has the same power train (if you can call
it that) and motor as the Yamaha Vino, I have to at least pass this
along...
Mine came with the restrictions removed (it's a 2001, bought in the
States) and until I got it broke in, I never much tried running it
wide open except for a very few times, and then only short distances.
Granted, it's practically brand new, but after putting about 200 miles
on it, I started running premium gasoline in it (93 octane, U.S.
standard.) Previously in this NG I had stated that it would "peg" the
40 mph indicated on the speedometer. At the time, I didn't realize
that it didn't have a peg to stop the speedo. Well, it goes quite a
bit faster than where the peg ought to be, as a matter of fact, I kind
of worried about breaking it. But to get to my point, suffice it to
say that I feel like it could run 70 easily with only a change in the
gearing, that is, if RPM were the only factor. If it took more gas to
maintain that speed at the same RPM's that I'm running now, then maybe
not. But the RPM's I'm getting now coupled with only a small gearing
change (unlike the 70% improvement as stated on the Taffspeed website
that was quoted here) could presumably put my Jog into the 65, maybe
even 70 MPH range. I'd never ride it that fast, because as it is, I
have to keep a close eye out for ANY road debris, but that's my
opinion, anyway. To use a familiar usenet expression that seems quite
fitting here, YMMV. Sorry I'm so late on this thread, I've been too
busy working and having fun on the Jog to post!
candeh
P.S- Hey, by the way, I saw a 2001 Jog on a show called "The Tourist"
on the Travel Channel (a cable television channel in the U.S.) I
thought that was pretty cool! The host of the show was riding it
around in Quebec Canada, by the way... I'm in the Southeastern US.
