the forum has moved itistheride.boards.net/index.cgii have a stock peace sports 50cc retro and i was wanting to change out the roller weights to gain a little more speed. can anyone tell me what the stock weights weigh in this scooter? and if so what would be a good size to get to gain some more speed? i know the dimensions are 16mmx13mm just dont know the weight of the stock ones. also would i need to do anything else besides just swapping out the weights, like adjusting anything else? thanks |

Roller weights will not change you top speed, they just determine how quick you will get there. The correct or ideal weights of the rollers will be based on your body weight more then anything else and will require trial and error tuning based on how the rest of the scooter is set up.
You can get a good guideline though but to dial them in requires testing.

You may have 8g stock. You can switch to Slider weights. If you want top speed, get sliders about the same, around 7g. Sliders have a different shape and supposedly can push the variator out further, which is your top gear. you can mix 6g and 7g sliders to find your perfect weight.
You could also purchase a performance variator. The ramps are curved and are supposed to allow a smoother operation.
Have you installed a larger main jet yet?

Start with 5 gram and go from there. Or, instead of paying $10+ for one set, you can buy a set of 36 variety rollers for $30 on eBay to find what works best for you. I wish I had just done that instead of buying one set at a time.

Start with determining what you actually have in there stock. Take them out. Go to the post office, or buy a cheap set of HF scales.
Then purchase a few different sets of rollers to play with. What you or everyone else, "thinks" they should be.They are cheap compared to Sliders, and those are you're main investment.
Once you have the roller weights that work for you, +1gram and order the correct size Dr Pulley sliders.
If you change to a different variator, it will change all of that, so if you decide to do that, do it first, of course.
;D or just do what he said > ltdhpp

So higher rpm's will not give you a higher speed due to lighter weights?....did not know that...so heavy weights that load your engine and bog it down...will? |

Proper weight tuning simply keeps the power band, in the proper place. You are looking for at best a happy medium.
That's why your variator weights generally go up with a BBK. Now you have to torque to throw the heavier weights out at lower rpms, and the weight needed to climb the belt all the way to the limits of the variator, to minimize top end loss.

Lighter weights only give you better acceleration, and may hurt top speed if they are "too light" and don't let the variator pulley open back up for a better top-speed 'gearing' , whatever you call that in CVT lingo.
Some people are happy in the middle, some go light and take the hit on top speed. It was minor in my case, and I don't need to go over 40 on mine anyway...
What some one "should get" depends on what they want, how the scooter runs, how often you see hills, how much you weigh... the only correct answer is: experiment! Throw a torque spring in there too, and experiment some more.

Yeah, I would go with a stiffer torque spring first. Will act like lighter rollars, but keeps you in a more predictable rpm range, and is the only thing that helps with hills. Keep your stock rollars and get stiffer torque spring, it'll work way better on hills and improve acceleration.

I had 5 gram rollers on my stock 2012 tao tao atm 50-a1 top speed was 28 to 29 and took forever to get there if there at all, but most of the time i cruised around 25 which sucked. I recently decided to try changing my rollers to 4.5 gram ones and i have much better acceleration until top speed and im actually going over thirty easily. Why so slow you ask when other people are going faster on stock scooters. Well I am 260 pounds and i live in reno Nv which is over 5000 feet. My advice is to remove your stock rollers and weigh them if you are a heavy guy try going down to 4 or 4.5 gram rollers if you are under 175 pounds try 5 or 6 gram rollers just remember 49cc engines do have limitations and can only do so much on the power department so you wont do too much past 30 unles you do tons of modifications. hope this helps and please ask if any questions.

Hi Welcome aboard Pleased to meet you And that's not all ways the case with 50 cc scooters as they are all not all equal in terms of performance. My Puma angel in stock form could hit a high of 40 mph and after the upgrades a little over 50 My new aprilia SR 50 in stock form has hit a high of 51 so far and that's running her below her maximum rpms If i decide to upgrade her i can easily expect speeds of 60+ mph So its not wise to generalize these scoots as they all perform differently. Take care and ride safely Yours Hank |

Hank, I totally agree.. My 50cc 4T would hit 45 stock gps verified, and I way over 200lbs.. But my 50cc baja, will only do 40mph verified.. There are differences even when looking at 4T's.. You have to fine tune each individual motor as if it was ur first.. No "general" tune will work on even two scooters of the same make and model.. See what it has, go up or down accordingly, and then start your tune.. It might cost a bit more to buy weights, but in the long run you will be much more happy with it.. Good luck..
