As above, whats the pitch on your china bike, my lifan i brought has a different pitch to the thumpstar and crf, they are 420 i had a mate that snapped his chain i he grabbed a spare off me but didn't fit his bike because my spare was a DID ER 420.

This is more a curiosity than anything , ive got spare front sprockets so im just gunna run a 16T on my new lifan
 
#420 on mine
#420 on the ST50
#428 on the PitproLE
 
Damn, sounds like yellow prox does'nt love you no more Sidney:D

This is gerneral rule of thumb
50cc 2 stroke = 415
65cc "" '' = 420
85cc " " = 428
or like a CRF 150 runs a 428

chain........pitch.............inner rolloerwidth...............................................
415..........1/2".................3/16.............................................................
420...........1/2.................1/4...............................................................
428...........1/2..................5/1..............................................................
a 428 = 5000lb tensile strength or upto 150cc or 40HP
BIT
