WR400F Jetting Question?

Recommended Posts

I've got a 2000 WR400F with a FMF Q Series Muffler and a TwinAir airfilter. I've recently purchased a YZ throttle stop to get full travel and I'm going to do the grey wire trick when I install it. I was wondering what kind of jetting mods will I have to do once I do this. I ride all over Colorado so my altitude is roughly 5,000 to 8,000ft everytime I go out. Are there any other Colorado or high altitude riders with similar setups? If so what kind of jetting do you find to be efficient? I'm just looking for a starting point when I go to get it all dialed up after the mods are finished.
