XR400 w/ Pro Circuit Pipe Jetting

Recommended Posts

Hi everyone. I bought an '01 XR400R a few years back and I've finally gained enough experience to know that the jetting is incorrect on it. The owner before me put an aftermarket Pro-Circuit exhaust pipe but never changed the jets to match it. I've noticed that while running on half-choke, the bike is extremely responsive and quick. Without choke, it runs like crap. I'm thinking the pilot jet is to blame - does anyone know what kind of jetting I should be running on it?

Thanks,

JuhCoby
