FECK! There shouldn't be anything in the exhaust to actually burn if it's a metal exhaust (which it looks to be, Scorpion[1]?). Only thing I can think that might burn is the rubber strap and I've got my exhaust very hot (trackdays with a road silencer) with no signs of anything going wrong.

At a guess either the fueling or ign has gone wrong and an amount of petrol has entered the silencer and burnt off.

Could the packing in the exhaust have been the cause of the fire.

Even if not I would contact the manufactures as they might be interested.

It doesn't really burn, unless your motor is soaking it in oil for you? More of a 2 stroke problem that though.

I say remove the can and see how it runs.

fire brigade guys (think they appeared cause a passing ambulance stopped to check i was ok and hadn't come off) reckoned that it was the packing of the exhaust that was on fire - flames were coming from inside and around the metal bracket from inside.

I was amazed - and restored some of my faith in people - by the amount of people that stopped to check i was ok whilst i was waiting for the breakdown to appear.

Mmmh could have happened to any bike then, though strange if it was the packing. How old is the can, and how many miles do you get to a tank?

Unless it's been re-filled with something strange there just shouldn't be anything to burn. The rock-wool won't burn so the only thing is if it's been soaked with oil or petrol.

If the packing was on fire it is one of two things;

1) Wrong material has been used in the packing (only applicable if it was recently repacked)

2) A flammable substance has entered the silencer and soaked packing causing it to ignite.

So who packed it with loft insulation?

Sounds like a good reason not to have any packing to me

Bad luck mate. Lissa told me that the packing burnt out of their art can, which I now have on my bike.
