Hello all...First let me say that this is a great source of information on all things BANSHEE! Now, on to my question: I am interested in buying a NOSS head to increase compression ratio (the stock setup just isn't enough squeeze). The need for race fuel is no concern i run it in my car anyway. But, I do need to know how much is too much for the unwelded factory crank? Does 175 psi sound about right? If not, then how much? I'll weld mine or get an aftermarket when I'm due a rebuild, but my bike is only a few months old. One more thing, I'm still up in the air on pipe selection, but I have my eye on Pro Circuits. Do they respond well to porting on down the road? Any help will be appreciated. Thanks.
