The bore size and wrist pin id is the same on all sohc 750's mate, but the shape of the crown changed several times.
I don't think that's a major issue though, the Wiseco 836cc pistons will fit all but the F2/F3 (and they'll still work, but due to the larger combustion chamber on the F2/F3, will reduce the compression ratio) with the one dome shape.
I've just installed the higher dome F2/F3 pistons in an F2 engine fitted with a K6 cylinder block and head, and while it's running ok in my driveway, I haven't ridden it anywhere yet to give me the confidence to recommend it.
Bottom line, is yes, those EBay pistons will probably work fine. Cheers, Terry.
