I had 20,000+ miles on mine when I replaced the dampers, and not because they where bad, but I was in there doing a stator.. they can last a long time, and we dont know why exactly some last longer than others. maybe its the maintainance schedule (oil changes specifically) and type of oil used during changes.

That's what I thought, acidic oil and maybe some excess heat. Have seen a few stators come out all coked up with sludgy engine cases. Once those bushings get hardened up, they probably don't hold together much longer. It's either two or three of them that have those little ridges that probably break right off.

I used the penny method. The penny held, but it was difficult to remove. I am assuming 400 ft lbs, as that's what the torque wrench is rated for. Nothing looked damaged.

In the grand scheme of costs, the dampers are pretty cheap, and important.
I'm just running into budgetary issues and trying to cut costs. I'm up to about $800 (honing cylinders, rings, new camshaft and rocker, engine mounts, all the gaskets).

I am strongly considering skipping reworking the heads/valve. That's $200 in parts and $500 in labor (I don't have the tools for that). Another $400 if I buy new valves.

If there's still a good margin on the valves, it won't need new ones. You could just remove the carbon, lap the valves to the seats (keep each valve in it's original position), and be sure to clean any varnish from the valve stems (and remove varnish from valve guides).

I used a rag instead of a penny. It locked up the gears fine. The Clymer manual got this one right. It says the threads are left hand. Where did you get a torque wrench that goes up to 400 lbs.? We had those at work. You needed something that big to compress the springs on air brakes. But the biggest one I have at home is only 150 ft.lbs.

I am a motorcyclist, NOT a biker.

I believe my manual also said it was left-hand. I just got ahead of myself.

The specs on the wrench say 400 lbs. It's not that big or expensive either.

Didn't realize it was an impact gun, that baby would knock the bolts off without blocking the crank.

Mistakes will be made! I aced the left/right threads and moofed the gear placement. There's even pic in the manual.
