GSXR 6" rear

[GVH]

I have a 1999 GSXR 6" rearend from another project. Any idea how easy it might be to fit this on a GS

[JamesG]

Won't.

There is barely enough room between the swingarm to fit that wheel. not to mention a tire.

You would have to graft a bigger SA on too.

[GVH]

I have the full swingarm, brakes, axle and all. I will need to measure it up to see it it comes close.

Even if you get the swingarm, wheel, tire, etc. to all fit, I seriously doubt you'll be able to get the chain square between the countershaft sprocket and wheel sprocket. It was a Buddha Loves You lining the chain up without rubbing the 160/60-17 tire and 4" wheel on my bike.

[GVH]

Fair enough. I have a 1977 GS550 project in mind.

Servus,

I have a 6,25" with 200/50-17 Tyre in my GS.

How'd you get the chain aligned Jim?

I believe they use an outboard bearing on a short stub floater shaft or some like that. The idea is this... extend the countershaft spline by welding a similar (or different spline to it). Mount the countershaft sproket to it, then that shaft almost makes contact with the case but its got a bearing that's slipped on and the bearing is seated in the sproket cover. The real limiting condition is when the chain has to run through the middle of the frame... which it will real soon... at which point you can cut the frame off... cos well if you need a 6.25 inch rear tire... you dont know to ride. OK OK let the killing/flaming begin.... Ok never mind but they run the chain sorta tilted and pretty soon the sprokets are looking like a wood saw blade. So new sprokets every race. Atleast for a while Cedric Smith's bike was that way.
Cool.

What did you mean with : How'd you get the chain aligned Jim?

Fatter wheel will push the rear sproket further out. So the rear sproket needs to line up with the front sproket. Usually they move the front sproket also out by the same amount. How dod you manage that with sich a wide rear wheel.
Cool.

Servus,

in the front is a offsetsprocket with 8mm further out and then you have the same amount.

that wheel/tire is awsome

[werase643]

slight overkill but executed nicely


nobody mentioned anything about what looks like a cast aluminum subframe...R6 may-B?
