May 30, 200818 yr I hope everyones suggestions help you. But if your bike was used when you got it and you only serviced the front and rear sections of the exhaust, the center is due anyway. Try burning it out as a last resort before you do anything major. I can tell you I did eveything that has been suggested thus far and burning out the center section is what fixed it. I would hate to see you spend alot of $$$$ and still have it knock when your done. Good Luck.
