A 0.0005" run-out variation is pretty small and could easily be attributable to measuring technique.

Maybe temperatures of all components when measuring, or using different measuring tools? :nix:

You do realize that you're making a lot of people jealous by having a stock flywheel assembly that's got 40K miles and only .002" runout.

I don't think he was worried, I think he was just bragging!

Yes, .002 runout, i'd say run it. We checked mine on my 2011 RG and it was under .003. I proceeded with S&S 110 drop in. Anyone see there 110 drop in come in with the pistons down in the hole and if so, how much?

To kind of put it into perspective, Feuling says you can run their pump and plate with 3 to 4 thou runout, and their stuff is very precise and picky.

Like Hoss says, I'd be bragging too if my runout was that good on a stock flywheel assembly after that many miles.  Your bottom end appears in very good shape, in my opinion.

My 05 was .005". I used a conversion cam setup.

It's within service limit. Nothing to fix at this point.
