I just bought my first scooter a week ago. It's a jonway sunny 50 cc 139qmb. I wanted it a little faster so i wouldnt be so slow in traffic. I didnt want to add exhaust or intake. i like it to look totally stock with no mods. so i ordered some leo vince 16x13 5.1 gram rollers. I've never worked on a scooter before but am mechanically inclined. i looked at a video on "how to replace your rollers without an impact wrench" on youtube. video was good. a word to the wise get an 18v impact wrench (i had to). it took me about 30 minutes to do the whole thing.
ALL I CAN SAY IS HOLY SH*T!!! it was unbelievable the gain i got. i weight about 230lbs. my scoot easily does 40mph. goes uphill at about 32-35mph.
i dont know if this gain in speed is common but for 16 dollars shipped to my door, i cant believe it. I also use 93 octane. my stock rollers weight 6.4 grams.
