Dan: Don Grubee said he will have them in a month but I'm not sure if Jeremy at bird dog will be getting them right away. I haven't heard back. I did send him a message enquireing about them. I couldn't tell from the pictures if they have a garter spring or not maybe someone who is more formiliar with clutches has seen this design and knows. I also asked about a bearing design for the racer and bell fit together and he said it wouldn't be feasable and retrofit the the current gearbox design.

I drilled the 9 holes in my clutch spring groove and the chattering went away.
