Ok, so I've been attempting to fit an 08 rear wheel on my 03/04 636 swingarm. Bill from Fullthrottle made me a spacer setup that fit 05/06 wheels for his latest setup, which is when I started to find out that the 07/08 where in fact different wheels.
So far I've learned that:
07/08 wheel hub is 2mm wider on the right hand side than 05/06 wheels. I guessed this because the 05/06 brake side wheel spacer is a 18mm, and the 07/08 is a 16mm. This could mean that the swingarms are a different dimensions, but I took a chance and took 2mm off the spacer and everything fit perfect on the brake side.
03/04 and 05/06 have the same cush drive part #, 07/08 uses a different cush drive (03-06 mounts, not sure if there is a difference in the thickness, I tossed my 07/08 hub as the bearings where bad and it looked the same as the 3 other 03-06 hubs had laying around).
So this is where I'm currently at. When I put on my 08 wheel with 03/04 cush drive and spacer, I have a few mm gap on the left side that goes away when I tighten everything down a bit. I know this won't affect me much, but I want to figure out exactly why I have this gap.
What's left to figure out is if there are any differences in the wheel hub on the sprocket side between the 05/06 and 07/08 and also, what the difference is between the 03-06 and 07/08 cush drives. If anyone has any information I'd greatly appreciate it.
Edit: Also, I realize some people may have mounted 07/08 wheels with some setups just fine. Most setups with a Nissin front caliper for the hb and stock rear caliper have a lot of room for slop. The Brembo caliper I'm using for my footbrake I believe has 6mm of clearance pad to pad, with a 5.5mm rotor stuck in between them, so there isn't much room for slop.
