Just wanted to share my buggy. It's a 2008 gk-06 with a 2003 GSXR1000 motor swap, power commander, custom cage, welded differential, fox shocks, sparco pedals and steering wheel, 1.5:1 steering quickener, yoshimura titanium header, yosimura muffler, custom front control arms with heims, reinforced spindles, custom paint, beadlined frame, removable doors and more. Its done 90 mph in 4th gear. I haven't found the fortitude to hit 5th yet lol. I finished this build up about a year ago and have really put it through some hell since then. I've broken some things in the gearbox along the way but its surprisingly handled the motor better than I expected. Its eaten the open differential so I welded it solid making it a locked rear and it's been good since and now goes just about anywhere I point it and I've done some pretty nasty hills and holes with it. I also broke one input shaft during a drag race with a turbo maverick (I was smoking him before it broke shifting to third) but i believe that was my fault the way I initially attached the hub which weakened the shaft. I replaced it and just welded the hub directly to the new shaft and everything has held up fine since. I love this thing and have a heart attack everytime I drive it. Let me know what you think.

Cool build man! Do you have any pix of how you set up the gearbox to run a chain? Getting ready to sway mine and the gearbox in the only real mystery

I used the factory motor output shaft (gearbox input shaft) whatever you want to call it. Purchased a 3/4" bore go cart sprocket hub and mating 530 chain 31 tooth sprocket from Ebay I then installed the gearbox and marked the input shaft where the hub should sit to line the new sprocket up with the gsxr sprocket. I took the hub and shaft to a local machine shop and had them turn down the input shaft just a tiny bit on the motor side to create a ledge which the hub would sit against and had them open the sprocket hub accordingly to create a light press fit between the shaft and hub. Finally I installed the hub and welded it directly to the shaft on both sides of the hub. I only have one picture of the hub installed on the shaft before I welded it on my phone but i can try to get a couple more pics for you this weekend.
