I just added a HMF slip on and DynoJet Kit bike is running great but at what I think is redline it starts to cut out. It did not do this before the upgrades. Does that sound normal that the upgrades gave me a little more pull range that I hit the limiter or is there some tuning left to do. What does the limiter act like when you achieve the cut off limit? This new territory for me.

when you hit the rev limiter it cuts off the spark so it will just stutter. with teh mods you have, your bike will rev faster and pull hard so it is a good posiblility that you are hitting the rev limiter unless you are not jetter correctly and that could cause a stutter.

With the mods you put on it will make it easier to get to the rev limiter, if you are jetted correctly i would suggest a rev box.
