and the stage 2 is not available :mad:

for the timing chain,take one of a CRF450

and you don't need to change anything with your rockers or your valves springs with Hotcams cams

you will be fine with a old stage 2 or new stage 3 hot cam in the stock bore 11:1 compression piston. thats what i have with MX porting and it made a huge difference.
