best mod for 03

Recommended Posts

If you own an 03 and have not yet installed a stage I cam, do so NOW ! There should be a post that reads things you should do without hesitation, and this is one of them ! It gives the bike its motor back. It now feels like my 02 did with a WB pipe on it. For 140 bucks its a complete no brainer. Non patiently waiting for the 05.

:thumbsup:YEP!!!! I just installed the HotCam Stage 1 also and it definitly woke up the bottom and mid-range BIG TIME! It is the best mod on the 03CRF.

Most of my riding is both sigle track and motocross. Anybody on the fence for more of this type of power should get this mod.

KIrk out.

How will this effect the valve issues? Some peoplw say the ramp speed of the stock cam is what's causing the valves to slam into the seats and causing the wear issues. Ron Hamp, any suggestions on this?

If it hammers the valaves out I don't care , it's worth it. You just need to keep an eye on them. It only takes 20 minutes to check and be done. I'll keep track of hours and keep it posted.
