I just Did my motor a few days ago. If you do the piston and cams you will need to remap your powercomander. It is well worth it! All I did was a 13.5 to 1 piston and stage 1 hot cams. I also built a custom intake. The bike already had a sparks pipe. Well the thing sounds like machine gun now and outpulls my friends 08 honda with a piston and a HRC kit! Before in a drag race he would beat me 3 out of 4 times. Now its not even a challange. The JE piston is just under $200 and you can find hotcams on ebay for around $160-$180 each. Stock gaskets run about $30 for head and base.Do i need hot cams if i install new high comp pistons? And how much power will i gain with just pistons, and just cams, and finally how much power with both together?
Wait also need prices?
