    Right due to an issue I had to get another engine for my bonneville, it should have been a 790cc but looks like it's an 865cc instead! Ebay for you? Right can I put the bigger barrels pistons and head onto original bottom end as the engine number was literally cut out of the crankcase half so not an option. Please help! Ta John

    I'd say yes.
    The bike's are identical except for ancillary equipment. So the engine Top and bottom would no doubt be same. The cam's are different between 790 and 865 , early motors were top end performance and later EFI motor midrange torque.
    But all the rest would be same same

    Welcome to the family. Not sure on your question but it looks like it will go. I have a friend who fitted bigger barrels and racing high lift cams so i recon it can be done.
