Stalling 2003 Wr450

Help please,

I have an 2003 Wr450, bog standard with a new JD Jetting Kit (blue needle 2nd clip from the top, 168 main jet).

Seems to stall when accelerating from idle, mainly notice it when doing a lot of tight single track. Increasing the idle speed seems to improve the problems, but then idle is to fast.

This was also happening before installing the JD kit.

Any ideas :banghead: ?


Try a 48 pilot jet and a #40 leak jet and the red needle in clip #5
