Gap your plugs to .28
Gap your plugs to .28
Back to being stock and slow
Do this first and see what happens. If it doesnt get better go to .24 gap. I am not saying to leave your plugs gapped that low but it will tell you if you have a weak ignition system. If the gapping doesnt improve anything then it may be tuning, a bad wire, bad dizzy, etc. There are a ton of things that can go wrong. If you cant figure it out feel free to bring it by for us to take a look at.
