thanks Jaffa, G put me on to one on Ebay that I think will work . waiting for it's arrival. While I got her up might as well do that clutch .....

To summarize (late to the discussion) all of the sprocket carriers are the same starting from the 907 on up, except for:
- Bearing size (easy enough to change)
- New versus old pins (RH Vs, LH thread ) (although the pin into the wheel are the same size)
- Carriers for 4.5" wheels are machined a bit more on the sprocket side to bring the chainline inboard more than the 5.5" rims. (5 speed transmission compared the 6 speed transmission) But they started as the same casting as indicated by the numbers on them.

E-bay or used is your best deal as few people want them. If you run different gearing for trackdays or such, its a lot easier to have a spare sprocket carriers with different sprockets and just swap them out.

Get one from a 900 Monster or SS and you should be fine.
