The guy who is building them was there the whole time.It's Benson's new primary clutch. For those of you that have been around a while you will remember that he tried doing a drive clutch years ago. It weighed quite a bit more than the stock Polaris clutch and it wasn't real clear what would happen if you put twice the spinning weight on the end of a Polaris domestic twin crank.
I looked at it, didn't really have anyone there that could give me any info on it. No info on weight or supposed advantages or anything really.
