Dear friend im pretty sure unless im mistaken the bore size is correct, we went through many obsticles not to mension the long procedure in putting in a different type of sleeve that no one in my state is capable of doing this type of job not to mention parts and tunning took awhile but weve succeded and turbocharged it. But if you are interested i could email you the paper works for the bore and piston information. i might decide to add it on ebay to let people see and read the info on it.
even if he changed the sleeves, what kind of connecting rods is he using and what crank.
Lots of loose ends. Not to mention putting sleeves that big would need block machining and I'm not sure if it would work even with that. One cylinder would be 800cc, its alot for a cylinder. Cant imagine a high redline.
