Hey guys, I took an auger this weekend on a nasty rocky uphill and low-sided right on a rock and put a decent sized dent in my headpipe. It's about 1" in dia., and I'm guessing i'm flowing about 75% ? The bike seemed to run fine, but until I can find a used replacement pipe (I got no desire to spend $340 on a new one). Should I not run the bike ? Can You possibly burn a valve and or piston when you have an exhaust restriction ? BTW if anyone can hook me up with a clean 2007 OEM headpipe I would appreciate it ! Thanks!
