That actually sounds like the needle may be in the wrong position. Did you play with the clips on the needles?

I did not pop the tops, as the slides were working fine....carbs are stock, so I do not think there is adjustment besides what is stock, unless I try to shim it......I was thinking the same thing....

I don't know then. I'd have to check it out. Too bad I just sold those Mikuni flatslides. That would be a perfect fix
