Hey guys, greetings from Puerto Rico, I'm new to this forum so I will begin. I have a 66cc motorized bike, I have done the mods on the motor, including: port match, a little of cylinder sand, NT speed carburetror, removed piston skirt. I wanted to share with you this two pics, I just did that to the piston crown, I have read that those crown mods give to the bike more top end . What you guys think? Right now I have a broken tire sooo as soon as I fix it I will post the results.
PS: I'm thinking of buying a 39T sporcket.... any advice will be greatly appreciated.
Thank You!!!
