what is compatable between 700e and 750e?

That motor will not fit into your frame, without extensive frame modifications.

You need an '80-'82 GS750E to do a 7/11 mod.

little more detail. When you say extensive. Are the frame tubes in the way or do I need to fab a whole bunch of new mounts. I'm well skilled it welding and fabrication. If it will physically fit inside the frame tubes, then the rest of it is cake. or is the swingarm going to be in the way? either way, I'm still gonna follow this 1100 to auction and see if I can't pick it up for 300$ or so. Then again, it has to clear lien first.

I believe it is too tall.

I'll take a measurment. My 700 gave up the ghost this evening on my way home. gonna try and pull the head and have a look. waiting on the 750 cylinder and pistons I ordered off ebay. But if I can shoehorn an 1100 motor into the frame then i'm all over it.

89 GSXR 750 motor is probably the easiest "hop up" motor. GSXR1100 has been done as well but needed frame & tank mods from memory (again due to height).

Wish I'd known the 700 swinger was longer, depending on where that 1/2" is it could have helped me a lot in fitting that 5.5" wheel & 170 tyre...

Mine did that. Snapped a cam shaft in three, taking the cam chain and oil lines with it. Bought a head and used the lines and cams out of it, threw in a new chain and it's been healthy as a relatively healthy horse ever since.

Next time will most likely be a 1150 or new bike.
