Really nice knowing that the gear pitch is correct on the gears. I've built a few motors in my days and used gears that are not correct and they always wear out the cam chain. I will keep Graves in mind for my next engine the R1

I purchased a Graves racing services spec race bike with these camshaft sprockets already fitted. The perform like expected FLAWLESSLY!
