big bore info for sx r 700

[Shail800]

how big of a big bore can you get for a sxr 700 i know of the 780 big bore from hauck but its for racing on asphalt strickly race sled nothing else

problem will be when you get too big the skirts get too thin and the cylinders will want to crack at the exh ports and the bottoms of cylinders wont have much strength. I have gone bigger then 780's(73mm) before to 74mm but it starts to get THIN!! Honestly if you wanted bigger youd need to make custom sleeves for engine or get aftermarket cylinders for that engine base.

The 760 (73mm) is a very nice package.

Who does the 760 cylinders & what kind of HP are we talking?
Reliability good for drag racing on asphalt? 9000 Rs or higher?
