I want to widen my rear wheel to 7 inches. does anybody know if it can be done and or who does it and how much it might cost?
I like the look of the factory 83 1100 wheels but want to widen the rear.
 
Like this?

It would take a custom swingarm and an offset drive sprocket of at least 3" to make it work. The widest you're going to make fit the stock swingarm is a 4.5" wheel with a 160 width tire.
 
Check out the 300 kit. http://www.tracdynamics.com/

Don't know if it'll fit a GS but...it is an offset drive like Billy's talking about. I'm sure if you have the dough, they'll be glad to help you spend it.

5.5x17" GSXR wheel will fit in a 1100 swingarm. I got a 5.5x17" 2005 GSXR 750 with a 180 radial on the back of my bike with a 520 chain conversion and 5/8" offset front sprocket. Any bigger than 5.5" and you'll run into problems with the chain fouling the frame.

You might want to talk to a drag racer regarding getting a 7" on your bike, you'll likely need a big offset front sprocket and need to run the chain on the outside of the frame. Those guys get car slicks on the back of their bikes so anything's possible.

The superwide rears are fine if you're into riding in a straight line all the time, but cornering agility will be shot to hell.

Actually I just wanted to get a wider look, and wanted to see how far I could go.
I want to use the stock rear wheel, how wide is the stock wheel?
There must be some company out there that will cut and widen the stock rim.
I do have a stock 03 bandit swing arm floating around, I read somewhere in here that it can be used with out many mods.
 
Sandy Kosman widens stock wheels. but you better be sitting down when you find out how much it costs. Just put kosman racing in your search engine and it'll come up

For what it's going to cost to do the wheel you can probably go with a GSXR front end and wheels.
 
Here is the link to Kosman!

They are one ones to talk to if you want to widen your stock rims to keep the factory rim look. I had my stock rear rim widen on my Roadstar Warrior from a 17 X 6 to a 18 X 8.5 to allow it to fit a 240 tire. Yes, they made it bigger and wider! I also just finished installing a set of 95 GSXR 1100 wheels on my GS1100esd yesterday to go up to a 5.5 wide rim for my 180 tire in the rear. It looks great!
 
Anything wider than a 180 and the chain will be running through the frame.

And even with a 180, you may still have to make some mods to get the chain to not rub the frame - 520 chain conversion, machining down the sprocket carrier etc etc.
 
Hitting the inside of the frame with a hammer to get some clearance for the chain.

I hope you mean over 200 series otherwise your statement is waaaaaaaaaaaaaaay off...what tires are the AMA Superbike guys running? 180-190 and they corner verrrrrrrry well.

Not really. Don't forget that they are running chassis' developed for the big tires and many of the riders still don't like what the big rears do to the handling. The only reason they are running the big tires is because they need them to cope with the power levels. For many years, the superbikes ran 180's because they handled better, even when stock bikes were coming with 190's on them. It is still typical practice to put a 180 on for track use with stock 1000's at the club level.

Regardless of how big the rear tire is, the greater the mismatch between front and rear widths, the greater the effect the rear has on handling. A 120/160 combo is pretty neutral. A 120/180 combo wants to stand the bike up somewhat, a 120/190 combo is worse again and a 120/200 would be terrible. The super fat cruiser tires are a joke and it becomes a serious handling fault that almost prevents the bike turning into corners at all.
