yoshimura engines

[quadfmx]

I know there are 3 versions,
but the pro model the top one like borich runs as well as the other LTR yoshi riders,
are the engine the same
On yoshi's page it does not speift different cams etc for the pro motor,
I mean the porting could be different ,but the way it reads they are the same,
does anyone know?

the cams, porting, valves, everything is different in the factory motors yosh does. They also use a stock fly cut piston to fix +1 exhaust valves and deck the head and cylinder. The only thing the same in them packages and what borich runs are the sticker they put on your head.
