Has anyone fitted the 86 model 200 piston in an 85 model ? I know the 86 model has some cutouts presumably for the powervalve, but it may work. Some one might know ?

Thanks,
tom

5 years late but here's some info...the 86 and later piston will fit BUT you need to grind off the bottom 3mm from the skirt. Else it will contact the crank. I have installed the '86 Wiseco piston/rings and the bike is running excellent.
