Found a great thread on thumpertalk. I would like to pull out all the most useful information and consoldate it here...
http://www.thumpertalk.com/forum/showthread.php?t=331196There are 2 engine models:
- 163FML uses a 63.5mm-bore X 62.2mm-stroke.
- 169FML uses a 69mm-bore X 53mm-stroke.
Companies that rebadge Lifan and Zongshen bikes...
KPX, Jetmoto, Yamoto, Roketa
LF200GY-5 or LF200GY-2 are Model 163FML and are OHC. Any true Lifan bike will have a VIN # starting with LF.
Some Lifan engines are pushrod and some are OHC.
