I'm riding a 04 REV 440 this winter - My first time on a doo.

1. Does anyone know if the older torsion spring secondary works with the new belt and TRA 111 primary? Or are there some sheave angle complications that go with that?

2. What's the drive shaft diameter 25mm or 27mm? Teeth: 15 or 17?

3. Does anyone know if the 10 tooth sprocket fits the drive shaft, or is like the old MX chassis where you had to drop and roll the case?

I would really appreciate some help. I'm shaking off the Polaris cobwebs and trying something new.

Thanks.
