I've been looking at MSD and Dyna. MSD is what we use on our race car's and they have many upgrades for small engine and motorcycles. Dyna is mostly for motorcycles. But I have not found anything that would seem to work. Maybe somebody with more knowledge will have better luck then me.
Do any of you guy's remember the Answer Roost Boost? It's basically a amp for your ignition. I'm sure I could get one to work but they stopped making them 10 years ago. I've looked for one like crazy but have not found one.
Dyna has one, but it is for 4cyclinder motorcycle.
