    Welcome to the forum. A little more info would help us help you.
    Is it backfiring? Cutting in and out? Hitting the rev limiter? How high are the rpm's? Did this just start?...........etc, etc.

    you could be running quite rich, have the push rods set a little too tight, have too much overlap twix the intake and exhaust.:newsmile093:

    Do you smell alot of gas? If you are TOO rich it will cause this, what bafles do you have?

    I'd say your floating an exhaust valve if it's right near the rev limiter.........next question would be why in the world would you wanna rev it that high? ............but then again, that's none of my business.:shock

    Probably Normal with the pipes you are using. SHORTY & Python suggest it is what it is...

    Have the inserts/baffels been removed?

    Lots of gas and fire at 5500 RPM...
