What's the SECRET? Everyone always asks, "How do you put 05-08 GSXR 1k wheels on a Busa?" Well hopefully this will answer all of their questions. I asked on SEVERAL forums and I always got the same answer. "Mill an 1/8in on the rear brake hanger and BUY $30 wheel spacers from So-And-So... I talked to someone that bought the spacers and said they weren't the best quality, out of round and such. So I decided to do some R&D, measure everything myself and make my own. This is a Guide of how I did my swap.
REAR:
On the sprocket side you can just use an OEM 05-08 1000 wheel spacer (PIC 1). If you didn't get spacers with your wheels, that one is $15.10 on Bikebandit, or call your local dealer and maybe save on shipping.
On the Brake side, the 05-08 1K spacer is $18.73 on Bikebandit. You have to mill the rear brake hanger on the swingarm side .125" (1/8" or 3.175mm)(PIC 2 and 3). I am using a stretched 01-03 600 arm so I had to mill mine an Additional .125 for my application. I also had to grind off some of the bracing on the milled side so it wouldn't rub against the swingarm when the wheel is adjusted forward (PIC 3 and 4). But this may not be required on a Hayabusa swingarm.

I had 2 spacers of equal dimensions made by a machine shop with a lathe. I used the OEM 1k spacer to get the ID (PIC 5) and OD (PIC 6) (about .990†ID and 1.250†OD (The measurements in the pics may be slightly off, i'm not sure if my manual dial caliper was calibrated, just use them as reference for now.) put the wheel on with the OEM Busa nut spacer(Left), and threaded in the axle flush to the fork(Right). I slid the wheel from one side to the other and measured the distance with a Dial Caliper. It was roughly .25†so as long as the spacers are .125†EACH or wider (PIC 7), the wheel has room to be adjusted from side to side in the forks. I put the spacers in the wheel where the bearing seals are and installed the wheel and slid the axle through. (If the spacers were out of round, wouldn’t you think they would tear up your seals?) To adjust the wheel, I lightly tightened the Busa spacer down in the left fork and turned the 24mm axle until it was snug. Then I measured the distance with the fender mounting holes to the face of the rotors with the Dial Caliper to center the wheel. If it’s off center, just loosen the left spacer and slide it out a bit until you achieve equal measurements on both sides. After you get it centered, tighten the axle and 4 Fork Bolts to Spec and you’re all set. I’ll try to get more pics after I take some with a better camera than my phone. Enjoy!! =D
