Melted Microfibre cloth.

[Last Train]

I had a plastic carrier bag wrap itself around my exhaust header years ago.
It was a windy day and had just blown across the road in front of me.
I took a bit of shifting, I think I just hacked it off with a screwdriver in the end

I don't recommend that solution for you Bugsy.
There are far better methods listed above.

Thanks for all the suggestions. The bike's a minter so I don't want to mark it unnecessarily. I'll start it this afternoon and try the heat and WD40 trick. Cheers All.

Well, 2 lessons learnt. 1) Be more careful with microfibre cloths. 2) If heat got the mess there, heat will get it off. I ran the bike for a couple of minutes. Using a cotton rag soaked in WD40 I rubbed the hot pipe. The crap came off as a brown sticky mess (no, it didn't stink!). I repeated it once after the pipe cooled and the jobs a cracker. Cheers.

Is there anything WD40 can’t do?
