I building a bike for a friend.. These drive sprockets really need some imrovment ...
1st I know my chain is alligned
2nd when its kinda of loose it better then tight
3rd when its tight not too tight it acts like it want to come off the drive chain sprocket
4th I have my chain tensioner on the top. Does this matter. The frame is round , it seems to be a better fit..
I think its the cheap chain that came with the kit..Gt5 66cc.
Any insight would be greatly appreciated thx.. Your friend. Flounder
