Ok, here is what I got. 983 Price motor ported by Hauck. I thinking that the port timming is pretty much designed for low altitude. If I were to try and run tighter exaust system, (smaller pipes), do u think I could get this motor to build decent power at higher elevation. I'm looking at 7000' max 3000-5000 typical. I'm afraid it will proably just be alot of heat. Proably will make better than most but not any where near its potential.
Big Port Question?
