you could, but i don't know if it would be worth the trouble without a highcomp piston....

my buddy did with a 10:1 406 wiseco rated piston. so who knows what the actually compression was. he bike was noticably quicker than a piped 400ex. the key is leaving it in gear longer even though it feels like it needs to shift. i would actually consider the new stage 2 hotcam, even with a stock piston. i would consider installing a thinner head gasket at the same time. when my buddy went from a slip on to a full hmf, he had drastic gains again.

i installed a stage 2 and a lrd full system at the same time with the stock piston and there is a big difference! i have a lot of gains through all the gears. i am really happy with the cam and the full system.
