I have a 2006 crf450. It has a stock head pipe and a PRO-CIRCUIT T-4 SLIP ON.

I need to know if anyone has some jetting numbers for
2,700 feet.

Right,and is it an R or an X ? How's it running now ? Doug

It is a 450R. and I failed to say it has a Boyesen acceralator pump too. I don't think the pump makes a difference in the jetting, does it?

This'll do it. Any questions, you e-mail or call JD and he'll help you out.
It has recommended settings , just follow them.It comes with a bunch of jets,and two needles with custom tapers especially for your bike. The second needle is for high altitudes.

Most find that with the Boyeson you run the fuel screw out a little more, and the manual for the QS says that. Doug

JD Kit! Mines stock header and exhaust, but this kit was right on! Money VERY well spent!
