ALso interested in a more agressive cam for my 140cc
does any one have the stats for the standard cam?duration?
maybe crow cams could knock some thing up

The 140 cam has a 6mm lift. Which is better than stock cams in the past. I'll figure the duration tomorrow. This is one of the improvements that the genuine new Lifan 140 has over the other 140's which are simply 138's fitted with a bigger piston.
