Not to mention, Aftermarket forged pistons are heavier then the stock cast pistons. You'd slow your revs down.
I wouldnt have gone with bigger pistons either, but my cylendars were scored, so I had no choice, but to bore.
Even with high compression pistons and head gasket you can map to run 93 on the street. That's what I'm having to do. The bike runs better on Race fuel and a leaner map, but I do just fine on 93 octane and a rich map.

It also saves me from having to split the case etc..
That's right about where I'm at, 13.25:1. Out of all the stuff I did to my bike, The head work was the most noticable with the most gains. The head gasket isnt going to give you a whole bunch of HP. Maybe 5 if your lucky. You should consider getting the head ported while you have it off.

Cool! Good luck with that. I'm curious to see how it does.
