I was told to relocate the limiting washer behind the variator to keep the belt inline with the clutch to prevent pre mature belt wear, what do you think?
also what weight did you buy? I was going for the 7.5g I think. Just relocating the washer on my scooter and using stock weights and polishing where they slide, My tach goes past 40, but its a little dead in the mid range. 32 to 40+ it's good though.
The belts are pretty inexpensive, and mine has lasted for over 11 years so far. Replacing it is easier than putting that limiting washer back on. So, I say the improved velocity and acceleration are worth the wear and tear on the belt, and the motor.
From the videos, I saw the shams or where the belt rides and the limiter washer is in the back and if you look in the manual until shit imports the warranty if your take out the limiter washer
Hi Mr Wrench ..i marked my variator with a sharpie and discovered a good 7 or 8 milimeters still left of the mark on the outer edge still not being used .any ideas ?ive got Dr Pulleys in and i even tried grinding out the alloy of the ramps to about 1.5 mill to the outer edge .nothing changed much.should i change the variator to a Polini one as this is the stock uk restricted model?btw the variator has 18,000 miles on it
I just removed the spacer nothing else. Plan on doing the variator next. i also have a two brothers racing pipe not sure if that could have helped with the speed gain. It was on there before i removed the spacer.
Mine runs 45 MPH on flats and accelerates twice as fast. I have over sized tire on back and upgraded dr. Pulleys, and the Intake tube pulled. It also has 16K miles and runs flawlessly.

Can I remove the rev limiter washer and not have to change out the roller weights? There was no washer on my 2018 zuma. Half throttle is all I got but it goes 40mph.

Man this brings back memories, I rode a 2stroke 50cc scooter in Hawaii as my only transportation for 2years. I took off that variator and belt a bunch of times. I liked those slider weights. You can use lighter slider weights for faster acceleration or heavier for higher top speed. It was called and Adly 50cc.

@@RollingWrench thank you. I don't think I'd mess with the rev limiter but I would like to take that washer off. With the restrictor mine does miles 38 miles n hour. Which is pretty fast enough for where I live. I recently purchased a 2021 genuine roughhouse because they just continued the Yamaha 50 in North America. derestricted the roughhouse at the dealership and I get 45 miles per hour stock.
So i just bought one of these and it will bury the speedo, if i had to guess id say it runs about 47. But the other day i went downhill and noticed it was somehow restricted. Is that because of that spacer or what?
complete guess, teh rpm rev limiter is at max on flat and limits the already max output downhill, it is direct drive (using the pully system) at that point.
Yo! Awesome video, just did this on my older Yamaha Vino 50cc, and for some reason if anything it made it slower! Any reason why this could be? Thanks!👍
just get the polini variator and use 4.5g weights with this and you will do 48mph gps downhill and 41mph on flat gps with zuma and c3.. i weight 185. if you weigh more use slightly lighter weights and if you weigh a good bit less go for a bit heavier weights. the kit comes with 6.9g weights which is too heavy unless you weigh 115 pounds.
I love my Yamaha c3, it seems like its pretty underrated, too bad there is not much aftermarket support. I need a way better shock and from disc brakes, I ride in a mountain area lots of curves.
@@RollingWrenchive took off the restrictor washer and there is no difference in top speed .ive read that putting the restrictor washer on first is the way to go.before i do it,have u tried this?ive put 6g rollers in btw
Keep the shim, swapping your rollers helps with take off, acceleration, and top speed. Your bike is EFI so you need to remove the governor from the CDI. The 2t Zuma's have no rev limiters.
Hey dude love your channel. You know your stuff! I have a vino now but it’s got a sketchy carb. I want a faster scooter. Thinking ruckus or a c3. What’s the better machine? Thx!

i just picked up this scooter with 50miles on it. stored in a garage. it’s 12 years old. i emptied the tank and swapped batteries. if i’m not getting fuel to the plug where do i look for a solution? thanks.

my 2015 4 stroke zuma runs neck and neck with my cousins 05 2 stroke zuma, down hills i pull away. plus mine isnt noisy and doesnt need oil to mix. oh and will last 3 times as long. 2 stroke is old noisy tech.
Then your cousins scooter needs a tune up! I put 27k + miles on my ORIGINAL stock oem 2004 Zuma cylinder. The only reason I replaced it was because the flange where the exhaust bolts up gave out.

In Ohio, scooters are classified as motorcycles and you must obey all motorcycle laws. So you'll be fine as long as you have it registered, insured, and have a motorcycle license. The 20 mph restriction is for motorized bicycles/mopeds (it has to have pedals).
@@supercatforever I figured out that I wasn't getting the main pully nut tight enough. I cranked it down with all the ugga chuggas and she runs fine now.
That’s correct. By removing it, you will gain more top speed. You can play with it. Try it with the washer and without the washer, so you can see the difference.
It is very interesting. I live in Japan.I have yamaha Vino 4T. These mopeds in Japan are not restricted.it reaches about 60kph. But Japanese mopeds' legal speed is only 30kph! it is too slow!
Redsorgum that may have been what your speedometer said but likely the actual gps speed is a good bit lower. My zuma 125 says its going 55 mph but gps says 49 mph top speed.
@@davidbabin4813 Yamaha speedos are well known to be off by 3 or 4 mph. I removed the washer two years ago and get 44 mph now verified by GPS. Speedo is buried at 40.
That is corect it is not a spacer it is a washer which spreads the load on the aluminum fan from the center of that slide when you take that spacer/washer out it concentrates the force of that slide on the back side of that aluminum fan pulley and will dig into it destroying the aluminum fan . This whole concept is done to move the 2 halves of the veriator closer togather to push the belt further out on the diameter of the veriator . Such a miniscule amount that that washer would take out will not take you up to that high of a speed gain Maybe one mile an hour if that . The lighter roller weights or slides will make a difference in how fast you pick up speed though Depending on the weight of the rider the heavier the weight of the rider the lighter weights you want to use it keeps the engines RPM band higher for longer Keeping the engine in the optimal power band before pushing the belt to the outer diameter of the veriator .
