    7/10 conversion questions

    Wasn't sure which thread to post in, so going with general. My '78 750 engine bit the dust, and I'm looking at putting in a '79 1000 engine in the frame. I've seen this engine swap around the internet, but can't for the life of me find what possible frame modifications I would have to do to set it correctly. I've seen a little bit that at least the bottom part of the frame will have to be adjusted to get the sump to fit right, as well as the brackets, potentially. What other modifications would I have to do? Thanks.

    I have been on this site just shy of 10 years. I have seen many posts on the 7/11 upgrade, but can't recall a single one on 7/10. Also, I seem to recall that they were always Kat-to-Kat (Katana).

    2016 XL883L sigpic Two-tone blue and white. Almost 42 hp! Status: destroyed, now owned by the insurance company. The hole in my memory starts an hour before the accident and ends 24 hours after.

      I too have seen lots of stuff on putting a 16valve 1100 engine in a frame that previously held a 16valve 750. But I don’t recall any 8valve 1000 engines going into an early 8valve 750 frame.

        I appreciate the input! That's kinda interesting, I'm fairly new to engine swapping and I happened to stumble upon some threads about the 7/10, one guy on here and a couple threads on OldSchoolSuzuki.

          2V GS1000's, 4V GS750's, 4V GS1000's and 4V GS1100's all bolt right in to each other. I'd think the 2 V GS750 would be the same, but never remember anybody mentioning trying it.

            I suspect the 2V 750 is longer in the cases. It's the only one with a kickstart Never personally measured it.
