Not often done with that engine - good luck. You will likely be looking at custom pistons, possibly 3mm over - 815cc?
They don't explicitly mention the latest gen 750 but I don't think that the motor is monumentally changed from the 11-14 from the 06-10 model motors, but as mentioned 815cc's is what they are doing. http://www.kwsmotorsports.com/s750.htm
To me the perfect bike after riding a 2013 gsxr 750 would be a ABS 850cc sportbike, for the street, no need no more..... Im currently riding a very fast gsxr 1000 and sometimes I find it 2 much.
I have done over 2 dozen + 750 big bores. Most time we do 2mm 792cc as the 3mm 815cc dont last long (split cylinders) a properly built 792cc on GOOD gas will make min 160 and i have hit 170.2 on one but all conditions were perfect and it was $60/gal fuel. Typically most mine run U4.4 and make 162-165. They vary depending on year too. The 06-07 will make most top end but the 11-14 really work well too. 06-07 are the strongest cases to use. Most my guys (90% of them) use at trackdays and very little issues. But again some after 2 full years will develop cracks in cases below output shaft or worse, between cylinders (mainly the 08-10 cases) Very cool build and piss off 1000cc guys a LOT on track, but dont build one cheap!! Spend the money and do it right.
ed, could you PM me a build price please based on 06-07 792cc motor supplied to your door. Top end is more important to me for this unit mate.
