I can't say I care too much for the looks, but I am interested in this 201cc 4 Valve of yours. Do tell.

Its a beast. yx160 with the 4 valve head then i fitted a bigger liner and a 67mm yamaha R6 piston. making it 201cc.
The aim was to make a 100mph c90 but still a way off it yet. working progress.
working on a 68mm piston at the mo.
no substitute for CC's

Hello mate, how you doing
I already have one of your Yoshi mufflers and ss pipe fitted to my 12v C90, but I have now acquired a 6v C70 that could do with a new system, are you still making them. Would be nice to have a system that would fit a Lifan 110 if I slipped that motor in later. Would either of these systems fit the Lifan 110??
