The preferred mod for your bike (and mine) is the '83 1100E aluminum swinger. It's about an inch longer.

BTW Introduce yourself in the owners section, place your location in your info and lets see some pictures of this machine.

But it is NOT a bolt on and go mod. The 1100E swingarm pivot is larger in diameter than the 750s, so it will require either custom sleeves for the swinger bearings or the frame bosses for the pivot in the 750 frame need to to be drilled out large enough to accept the 1100 pivot...

Sadly true. If you go with the larger (16mm) pivot bolt and ream the frame you also need to shorten the bolt and cut new thread a little ways. The simpler and therefore preferable route would be custom bearing spacers. Also, you'll need to add 3 or 4 links to the chain either way.

thanks for the advice. i am also having carb. problems. i have taken the bottom bowl off and took neddle valve out and make sure the float works properly put it back together just to have one of the four to leak gas out of the overflow. i was wondering if it would be better to take the carbs off and soak overnight like i have read some people have done and if so how hard is it to get all four in sync with each other so they work properly. does anyone know a simple way or something im missing? i havent took the top off the carbs only the bottom am i missing something in the top? thanks for your time lee.

Check out BassCliff's site for which GateKeeper has provided a link. There is a guide for cleaning the VM carbs, float bowl heights and carb syncing. It's all there - take your time, do some reading and then get to it. There'll be plenty of help on the GSR to assist you as you go. The leaking carb is probably a dirty/sticky needle valve, but it's likely the carbs need a proper cleaning.
