Hi. This last fall I cleaned my top end and used a Moose gasket kit on the install.I thought twice about using the rubber exhaust gasket but had no patience to wait for a oem gasket(it's a metal crush ring).Bad move.Pulled my pipe today to replace a lower pipe mount and you guessed it......no rubber gasket.The small piece I found in the pipe was chewed on.I found no pieces in the silencer(TCII)This leads me to believe the rest is in the crank and everywhere in between.Has anyone else had this happen to them and did you pull the cylinder to clean up the mess?Thanks for your comments and it's ok to laugh.I'm trying to right now!
