83' GSX750E Engine upgrades- bigger engine or rebuild?

[gearhead13]

My 2 cents:
The 80-82 750's can run a long time with proper maintenance, I took my '82 apart at 60,000 km and there was very little wear on the main and rod bearings, and the thing still had 140# compression, I rebuilt it with wiseco pistons and cams and porting and carbs and ran the **** out of it for a couple seasons, no problems at all
The '83 and up 750 frame is smaller and wont take the 80-83 1100 engine AFAIK. Only gixxer and oil cooled kat motors fit. My '82 frame took the '82 1100 engine real easy with only one motor mount needed, all the same electrical hookups.

Correct, I have had around 40 suzukis and about 10 others of various brands through the last 30 yrs.

The 83& up 750s wont take the pre 86 1100's too tight.
The 82 down we used to take the 85 and down 1100's and slam them in and leave the 750 markings in and own the street races.
of course they do the same thing these days too with the newer crotch rockets.
