hybrid chinese motors and performance tuning

[foureasy]

i thought i would start a new thread about cylinder kits that fit the chinese bottom end with modifications, and all of the associated tricks in assembly and tuning that i have personally tried, and maybe some advice on some things i haven't. i don't even know where to start, so there probably wont be any coherence unless you ask questions.

soooooooo how can you be sure that one of these kits that you pick out is gunna work
for a pistion port set up?

REEDS! they are very important for a fixed gear bike, since you cant slip the clutch to get going. all the kits come with a piston, most of which have a 12mm wristpin, so you can smash that crappy chinese piston with a hammer. our motors have a 10mm, so your rod will need to be bushed and reamed to 12mm. you have quite a variety of moped pipes to choose from, some of which may work very well, but i build everything i can so i have no personal experience.

i still have stock timing and have no immediate plans to change it.

[furament]
