Well, when the VN is good, it's a lot of fun. Low end grunt or high revs, and smooth all the time. But if yours is buzzing that bad, it's probably the dampers. Rubber in the oil screen is an indicator, but not conclusive.
The stator is purely your call. I suppose you could go through the tests to see if there's any weakness. We lost TPE, so most sources are unproven or have horrible records. I did find one source for a rewind, we need a guinea pig to try them.
If you don't go for a stator, at least you'll know what it takes to get into it.
You probably need a cover gasket, the three o-rings for the screws, and an outer cover o-ring gasket, but I re-used that last one. Also a couple drops of Loctite.
If you have a local source for large bolts, that's all the puller is, with metric threads. The size is around here somewhere. I bought a puller for $11/ebay, could get a whole box of the bolts for $20 if I wanted to wait for the order.
Left-hand threads on the damper gear bolt. Always remember, the largest hole in the damper gear, remains empty.
Mine shook so bad, the hand grips were a blur and she walked across the garage on the centerstand. Had the damper gear and weight assembled wrong.
I prefer the engine tilt versus taking it completely out. I left the bevel gear, carbs, throttle cables, and exhaust manifolds on the engine.
