o,k here is the deal, several months ago I purchased a set of spoke rims from a guy, had no more than 2000 miles on them, had them mounted on my 04 retro and about a month ago added Dunlop WW'sI  have put about 1500 miles on the rims. Lately I have noticed a front end bounce especially at slow speeds took the bike in and had it balanced agin, still have the bounce. Took it back where I purchased the WW's and told them the front tire muct be bad, they checked and it was determined that I had a bad rim, there was nothing wrong with the tire, question is, how prone are rims to going bad, could the machine they had the rim spinning on give a bad out of round result, any insight would be greatly appreciated.

You should be able to check that yourself. Just get the front off the ground and put a stationary object next to the wheel and spin it. If it is out of round you can tell. You can use a erase marker to mark a line as it spins. If it's out of round you can tell by the line on the wheel. I've done this with car tires and wheels before for warpage and out of round.

Hope this helps.

thanks for that info HG, actually at the tire shop, they removed the tire from the rim, put the rim on what I assume was a balance machine what spins the rim, once the rim is spinning the shop guy places a arm attached to the machine on the edge of the rim as it spins and the arm is suppose to stay consistent as the rim spins. I noticed as the rim spinned the arm began to bounce. and that he said represents a bad rim. I am contemplating taking it to another shop and trying to get a second opinion, its just getting a bit expensive to keeep remoing the tire and having it remounted. I am just having trouble thinking that this rim could be damaged to the point that it is uselees, I dont do a lot of aggressive riding, no major bumps that I can recall, have heard something about the spokes not be in true, that the rim spokes can be adjusted.

having the wheel trued should be an option... IF the rim was horizontal when it was spinning at the shop and just wobbling up and down. If it was vertical, then it could be out of round, but that could also (possibly) be fixed by tightening/replacing some spokes. We used to do it all the time with bicycle rims. let us know what happens.

I feel the same way.
You should be able to tighten and loosen other spokes to make them not wobble,
which ones I have no Idea , but I use to do it on my dirt bikes and bicycles also

a good dealer would have told you that and fixed it for a fee, unless they are the spokes you can't adjust and they are fixed and sealed when you don't need a tube, but these are $$$$$$$ rims

I have a basic wheel truing and balancing stand.  I use a dial caliper to measure the run out.  I’ve rebuilt several spoked rims before and unless the spokes are stretched or the rim is damaged you (or a shop) should be able to true the rim back up (without removing the tire).  Prop up the tire on the bike and spin the rim.  Use anything you can find as a stationary pointer up close to the rim edge (coat hanger wire works great).  Once you identify the out of round section use the plastic handle of a screwdriver to rap on the spokes and listen to the tone.  They should sound (for the most part) the same.  If the tone changes quite a bit then you possible have some loose or stretched spokes.  It takes some practices to learn how to true it back up but it can be done.
