7/11 rear engine mount

[Upshotknothole]

So I’ve got a 750 that I want to stick an 1127 into, but I’m not positive that it’s going to stay a 7/11 in the long term. Might give the engine a rebuild over the winter and some new carbs if I can ever find a proper exhaust for it. Trying to decide if I should drill out the frame to fit the 12mm lower rear engine bold from the 1127, and sleeve the mounts later, or just run a sleeve inside the 1127 and leave the frame alone? 

If this was my only GSXR I’d just say fuck it and sell off the 750 lump, but I’ve got a 7/11 and an 11/12 that I need to finish and get back on the road and I still like the way 750s rev out and they’re fun to ride from time to time.

I think i'd go with a sleeve on the 1100 engine. then the frame is still standard.

Personally I’d probably go sleeve if you don’t think it’s a long term thing.

I have seen a de-bored rear mount with slim top hat spacers fitted from the outside of the mount but it’s not really ideal although it seemed to work.

Thanks, I’ll measure it up and order a sleeve then.
