hi guys, i have a Jinlun jl125t-13 moped, now i know that the lighter the roller weights the faster acceleration and heavier the roller weights the more top speed..... now i want a little more faster acceleration on my bike and i just want to know which lighter size roller weights is recommended for a 125cc??? oh and im not sure what stock ones is already in there? any help please?
First off, heavier rollers do not equal more top speed. It's like changing gears in a car; change at low revs and theres no power, but you still crawl up to the same speed (too heavy rollers). Stay on the rev limiter for 10 seconds in every gear and you over rev and don't accelerate (rollers too light). And then perfect rollers would be perfect gear changes. The best thing to do would be to take out your current rollers and weigh them, then take off a couple grams. Should be a good starting point. Unfortunatly, Chinese factories use whatever rollers they have lying about so there is no certain weight as standard, hence the need to weigh them to see what you have.
