Hi everyone,My son has a 2008 cr150r it has 15hrs race time.I installed cp piston13:1 and Hotcam stage II.Pluse cleaned head ports ,stock valves and springs.DrD step pipe and JD jets.What should I expect Would you add anything else?It ran like a scalded cat before rebuild.I need to button up a few items before I start it.Thanks

you just did everything i would suggest, besides suspension and such.

did you check valve clearance and tolerances?

why not aftermarket valves?

ii would def. put aftermarcket valves with a high comp. piston

I not only agree, but this is what I did also

Hi everyone,I am very happy with the results with hot cam II and cp 13:1 piston.When I rering the piston I will do new valves.I did a little port work on the head.The bike runs better than great.my son loves it,Pulls the wheel out of berms like you would not believe.I am running Sunnoco 110 the bike loves it. forgot a new FMF 4.1.sold DRD pipe
