I just picked up a leftover 03 WR 450 last week and have a miss while riding at a constant speed. I was riding at 55-60 mph in top gear, with the throttle open enought to hold speed. Some times it runs fine other times it misses. If I get on or off the gas it runs fine. Pilot was changed to one size above stock at 1.5 turns out. Didnt like the glowing header I got with the stock pilot. I tried richer and leaner on the needle with no luck. Any suggestions?

I've tried every possible setting and found you just have to live with it. Using the JD red needle helped but didn't get rid of it.

I lowered the gearing and lug it slightly to get rid of the stutter at constant speeds.
