Hi, new here. I have a 05 400 ex w/ a few small mods and having a problem when WOT.
It runs great all other times.
If im toped out in fifth and WOT for a little while, it will begin to cut out like its running out of gas. If I pull the clutch and give it a few revs,and it goes back to normal. I run no air lid, a k&n, a hmf sport series slip on muffler, and a aftermarket cdi. I jetted the carb to 165 main and a 42 pilot jet. I put a dif. needle in it and went one knotch down from orig.. What do you think the problem is? Is my main jet to small? I have not done a plug check yet when it does this. I will soon. As long as im not WOT for a while, it runs flawless. Any suggestions would be great,
thanks
