Two weeks I repacked my Big Gun silencer with MSR packing on my Cannibal. Yesterday(Sunday),it was my first long time riding it since the pipe was repacked. I was riding from about 2:30 until 7:00. At 7:00 there was no packing in it and the core fell down from the middle of the pipe to the bottom. How did the packing burn so quickly? Do you think I should buy an HMF pipe?

 

When you added the Big Gun, did you have the computer remapped?

 

I think, I got it at Marcum's ATV in Florida with the Big Gun on it. He was using it as a demo bike.
