To fit the rear wheel it's actually quite easy. The axles are pretty much the same and fit the bearings. So the 360 axle is used.
On the wheel the Ninja spacers are used, but on the brake bracket on the outside (towards the swingarm) you machine off 3/16" to move the wheel over to the right.
The chain adjusters are different thickness between both the CB & Ninja, the Ninja's being a bit thinner. So you use the screw/locknut set up from the CB on the Ninja chain adjuster. This gets the wheel centered within an 1/8 of an inch or less. If you used the whole CB chain adjuster set up, then it would be pretty much centered, but you'll have to take an 1/8" off the left side wheel spacer.
On the wheel you'll have to take the sprocket & mounting studs out to machine off 3/16" so the sprocket will line up with the chain run. To get more clearance between the sprocket mounting studs and rear shock, just used hardened, shouldered bolts.
The rest is easy welding on tabs to hang the braking system bits.
