get your torch, plug one end up tight, i use a cap that is the same diameter as my pipe because i happened to have one laying around. make sure it is plugged on tight, and if you use a metal cap, press it against a surface while you insert the torch head into the pipe to insure that it doesnt blow off and knock someones head off. when the torch is inside of the pipe, aim it at the edge of the dent, not the center, as it will gradually pull the pipe back to its original form. on a 125 pipe this may be more difficult on the front section as the pipe is MUCH narrower, but on our 250's pipe this has worked great, multiple times. saved us about 10 pipes so far.

Just to play things safe, I'd also take a close look at the exhaust flange on the cylinder too. I took a hard hit from someone (broadside) and it dented my pipe. Upon closer inspection, I noticed a fine crack in the flange. As I ran my fingers over it, a 2" long piece of the flange broke off in my hand. I had to take every nut, bolt, rubber, and plastic piece piece off the cylinder so the whole cylinder could be preheated prior to welding it back on ('96 KX125). The little load that hit me on the trail just disappeared and left me with the bill! Anyways, it might be wise to look in that area if you haven't already.

What if you have just a small dent in the expansion chamber the size of a quarter?

You can get it repaired if you really care about it, but if it isnt within 6in or so of where the pipe meets the cylinder, you dont need to worry about it as it really wont affect power very much.

If it's not that bad and it's not bothering you leave it alone, you'll be fine!

If it is minor like you say don't worry about it. Look around at your local track some day I wouldn't expect that there are to many bikes there that don't have a ding of some sort in the pipe.

I usually find that if I put something new on my bike it is usually dented, bent, scraped or twisted within a couple of weeks anyway. Go ride your bike and have fun.

A little dent like that wont take away any performance that youll be able to notice. Dont sweat it and ride on.

If it's just a little dent, it does not have that much of an impact. Just wait till you really jack it up.
