Re-jetting is required for optimum performance, even with a change in atmosphere.. letalone changine engine parts... Check to see what jets are in your carb, and then reference that with the tuning tips on the just kdx website

Hey dashound:
Straight from the "Every KDX rider should read this link:

>>1997 to 2003 KDX220

Stock run a 42 pilot jet,the stock R1173L jet needle in the second from the top clip position, a 142/145 main jet and fine tune the pilot circuit using the air screw.

With a performance pipe/expansion chamber, air box mods , the factory or after-market silencer and the stock 33mm carburetor run a 42 pilot, the stock R1173L jet needle in the second from the top clip position, a 145/148 main jet and fine tune the pilot circuit using the air screw.
