I planed down an old countershaft sprocket to about 1/8" thick and about 2" in diameter to use as a spacer to move the countershaft sprocket out for better alignment. I used the Gixxer caliper on a Katana 600 hanger to grab the Gixxer rotor. The torque arm is under the swingarm now. Just knock out your stock bearings and use them in the GSXR wheel. You also have to use a Katana bearing support in the sprocket carrier and your stock bearing support plus a small piece of steel tube the right size to equal the length of the Gixxer piece in the hub. Katana spacers on each side of the wheel.
To make the swingarm work I had to cut off the stock peg mounts on the frame and weld small plates to the outer edge of the frame for Gixxer rearsets. I'll have to flycut the frame where the pivot bolt goes through since the pivot point on the banana swingarm is about 1/4" wider than the stock swingarm. I can use my stock bushings and pivot bolt. The bushings will have to be shortened to fit the Gixxer unit. Then I'll have to weld on shock mounts for the new shock since the linkage for the GSXR is on the bottom of the shock. Swanny used the old centerstand tabs on the frame as a starting point for his lower mounting point. The top is no big deal.
