welcome to the australian zongstars, the inofficial chinarider zongshen 200 faction, membership 3 (you and me, plus spud as honorary lifetime member - if he wants to
).
as far as conversions go, i d mention my three faves for functionality:
drill 3 holes in airbox, rejet carbie, lower needle one notch (richer)
OR
get a proper mikuni slide carbie. there s a guy in SA who sells them, they are around 300 $ from memory.
header pipe from moto bike pipe shop + cheapo racing exhaust from chinese bike shop near you
aftermarket clarke tank
sound, speed, range: these three i enjoy most every time i ride. u can do heaps for the looks of the bike.
IMHO the chinese attempt at getting the honda red right, hmm, well, it failed. the green model was the worst of all, though. black and orange work. but thats IMHO only.
