I have an 05 WR450 all of the free mods, AIS removed,168 main jet, 48 pilot jet,YZ needle set mid way,Zip-Ty screw 1.5 turns out, baffle taken out, and now as I throttle up in neutral the engine runs real rough until about 1/2 throttle. What do you guys think fuel screw adj, or a larger pilot jet or something else.

I have a 45 pilot and 170 main with JD blue needle with an air screw between 1 1/2 to 2 turns out. Same free mods. My friends 04 same jets and stock needle, were at 3600ft. It says Cali so sea level for you? Might be to rich on low speed? check out jetting on this forum it has a massive amount of info!
