Not an FZR, but posting by request...

A while back I ditched the stock wheel and slapped in a 1992 Suzuki GS500E rear wheel.
I didn't so much like the tire width, though...not enough meat on the ground. Plus, I just wanted a wider rear wheel...and I wanted something that matched the front wheel.
So I built this:
Widened 1.5" (give or take a few mm...). Trued it up and welded the thing solid...and yeah, I had that gap in the middle filled (my guy did a fantastic job...looks like it was always this way).
I had a YZF600R rear wheel so I based most of my build off of that.
I had a HUGE problem with sprockets...the YZF600R came with 47-tooth sprockets...plus or minus a few...and that just doesn't fly with the GS750. I ended up having to go to the Wera forum and someone happened to notice that WR250F sprockets had similar dimensions....SCORE! I had to take a WR250F sprocket and drill the bolt holes out to 10.5mm and it slipped right on!
A gentleman on yzf600r.com (nu600rider) hooked me up with a great deal on the carrier above as well as an axle, caliper, caliper carrier, all the spacers, cush, brembo master, brake line...even the brake pedal. In the end I was able to put this all together:
I should have got a good before pic because I put it all together backwards the first time.
Slipped that bad boy in there...
...then I had to pull it all back apart because I forgot to put the caps on the end of the swingarm pivot...then again because I forgot to put the bearings in there...argg.
In the end this is what I ended up with:
My chain is about 2mm off...I'm having a spacer cut for it today...just have to keep my ride time tame until then.
I did have to put some shims behind the upper strut bolts, but they're long enough to be more than accommodating with my shocks. I also had to bend the push rod on my master cylinder a bit to get it to clear my swingarm, also had to shim my muffler out about 1/4". Only real frustrating thing was a brace for the brake caliper. I ended up drilling and pressing a stud through the swingarm main spar and I tweaked a dogbone from an FZR600 to fit...haven't tried it out. I'm going to go beat on the rear brake here in a bit and see how it holds/stops...I'm probably going to have to do something different, but I guess we'll see.
