Help Jetting needed for crf450 with athena 488 kit!

Recommended Posts

I have installed a athena 488 kit with ported head, power now and factory four exhaust in my 03 crf450. Where do I go with the jetting?

That's a tough question in itself, added to the fact that your location, altitude, etc. aren't stated. I did the same with my CRF and had to go to one sized smaller pilot and main, and my fuel screw was out 1 turn. Put in a Hot Cam, and now I'm starting from scratch! I'm sea level 85 degrees, high humidity.
