hi all, after a long straight i let off the throttle from being 75% open to fully closed and my friend behind me said sparks where coming out the back. any ideas what this is? i have a remus can and a smart TRE resistor i didnt feel anything happen and if it wasnt that the fact he was behind me i wouldnt of known.

If it's running alright, be right. Probably your exhaust packing dismantling itself. Just bits of hot fibreglass and carbon.

"Sounds" like the packing is breaking up during high temperature run within the silencer, may need re-packing with new material????
