Hi, was wondering if it is possible to fit a YZ426 engine of the same year onto a WR426, both 2001 models.
I know their is a slight difference in cam timing and gearbox but is their anything else that could cause issues?

 

Thanks

    As with any retro fit,    exhaust mounts /route, and engine mounts are the big point, B)

    it should be a straight fit, they are the same engine with a few internal changes thats all.
