Comet Duster

[p51mstg 520]

Here's a general snowmobiling question from my more formative years...  Back in the day, Polaris designed their own clutches (steel ones at first) that were so good that they set a standard to judge basically every other clutch.  There were engines and sleds that could compete, but clutching made a difference that few could compensate for.  That is, except for the Comet Duster.  It looked good and it worked good.

What I don't remember about those days is something that we take for granted now, and therein lies my query:

Could a person "tune" those old clutches, specifically the Duster?  Was that actually tunable with weights and springs like we think of tuning a clutch today?  Were they rebuildable?

I think I still have one sitting on a shelf..... It's just to look at though.  It's not going on a sled.

Yes, there are different springs for them and you added or removed weight with plastic pucks that go in the cover.

You can get all kinds of springs and weights (pucks) for them, and if you are like me, you'd get the heavy weights and drill holes to fine tune.  I must have 60 of those damn pucks and a half dozen springs.
