    If so what size jets are you using.

    I'm running 135's and I think they may be to big.

    OK, when I was running 135's mains the bike had a flat spot above 5K so I put in some 114's and the flat spot was just above idle so I was running lean all the time. I put in the biggest jets I had (no number on them but they are alot bigger than the 138's. I think they may be 150's). The flat spot is almost gone at max rpm and only happens for a split second now. So I'm going to raise the stock needles and see if it goes away.
