The proper way to check them is to dissassemble them, put them in v-blocks and measure the runout with a dial indicator. .2 mm is the maximum runout. If they are bent but not crimped, they can be straightened.

 

First gear 10'O clock wheelies and I weight about 240lbs, I doubt it if the front forks can be bent by a few wheelies, but excessive wheelies will not do any good either. Just curious to see what other people think.

I think the first symptom of excessive wheelies is fork oil leaks, correct me if I'm wrong. I’ve never seen people bend their forks by simply pulling wheelies, usually crashes, or running into something head-to-head.

 

If you're bending your forks from wheelies then your ***** are black and blue too ! Ball Sac'n Tank slapp'n !

 

I use a metal ruler to check them. You'll want to take them out of the triples because they usually bend right at the bottom of the lower triple. If the ruler doesn't lay perfect against the tube then you've got trouble. If it's not too bad they can be straightened, as mine were.

 

how much did they charge to get them straightened out?

 

I used the Frame Man in Sacramento California. They charged me $75 to straighten one tube. It was totally disassembled, I sent them just the stanchion tube by itself.
