I found a few threads but couldn't find anything to directly answer my question. How exact should I be when I am doing this. I have gotten the wheel true within 2 millimeters (maybe less). Is the only acceptable deviation 0mm? I worked at it for about an hour last night and worked on it a couple hours a few nights ago but can't seem to get the wheel to stop wobbling that 2 millimeters. I'm going to be selling the bike as soon as I get this wheel fixed. I'd like to do it right so I have a good conscience when selling it.

I found these posts that was pretty informative but didn't quite answer my question. Hoping you guys can steer me in the right direction.

Are you trying to "true" a previously bent wheel ? Bent is bent, you're not supposed to use spoke torque to straighten a bent wheel. When I re-lace wheels, I try to get near .060" of axial or radial runout. No need for tighter tolerence with a dirt bike wheel IMO...

It's often necessary to loosen some spokes in order to move a segment of the rim left or right. Once the spoke tension gets high enough, just tightening the spokes pulling left won't be enough to pull the rim left; you'll have to come off the spokes pulling right a little bit first.

Also, you'll find that you need to work with sets of 3 or 4 or more spokes near the deflecting spot, rather than one on one side and one on the other.

Once the wheel is straight, round, and on center, you can even up the torque a bit more.

And of course, as PB said, you can't fix bent with a spoke wrench. 2 mm is .080". That's not too bad, really, even on a street bike.

If the rim is not bent and the wheel was built right, you should never have to loosen spokes your just asking to mess stuff up. I mean they dont tighten themselves! Im comming from extensive bicycle experience and ive never had the pleasure to work on a dirt bike wheel that was off that much though!

Thanks guys. I've got the wheel true and round and back on the bike. It wasn't as far out of true as I thought it was.
