So I've done a lot of research and found a number of people running YZ250 GP Series #808M06640 single TiN ring piston kits in their RM250's. I've also read this was the set up that Carmichael and other top RM teams ran in their bikes. Obviously I am very keen to try this out in my RM, but I have some questions...My stock motor has a 1.45mm squish band, I understand the GP #808 piston is slightly taller? Will this potentially cause detonation? The bike has never suffered detonation before, running 98 octane UK premium pump fuel.I've never used a forged piston before, what is the running in method for these?How long will the piston/ring last? What is the recommended amount of hours on the ring/piston?
