Seized bolt on rear cylinder for exhaust.

I'm trying to get the bolt of the above so I can the exhaust off and get a new one one.

I think its seized, then the bolt has rounded off, its a 6mm, alan key fit. So I how to do I get this off? Why do the simple jobs turn into being a real pain in the ****

Use a Dremmel. Cut a slot in the head for a decent sized screwdriver bit and then use an impact driver on it. And lots of penetrating oil/wd40.

I reckon it's probably a 6mm socket headed bolt, other wise known as an Allen bolt - that's a brand name.
If you've goosed the head, it'll need cutting off, there is the slimmest possibility that you could hammer a slightly bigger hex bit into it and turn that instead - but I'm not hopeful.

'Cos you, like many others on here, don't have much experience of working with tools or motorcycles.

Right the good news is that I have got that bolt lose now, with aid of lots of wd40, so thats coming lose. Its a bit of pain but its lose enough.

However the bolt on the left side (nearside) of the bike that holds the exhaust system I aseume that you turn it left to undo no? (I have got the one on rightside off no problems) Thats dam tight as well, in the mean time I have sprayed with lots of wd40, gonna leave it to soak overnight.

Yup I'm a total novice, however more I praticse the better at I hope to become.

Don't need the bike tonight, my mate is driving and I'm drinking

Anti-clockwise = Undo/Loosen

Clockwise = Do up/Tighten

To paraphrase Sid Squid "'Cos you, like many others on here (myself included), don't have much experience of working with tools or motorcycles."

FFS throw away that can of WD40 and invest in a can of penetrating oil, don't go out tonight and save the beer money to buy some decent tools that don't knacker fasteners

Pro-Gas is awesome bolt-loosening spray. Spray copious amounts on the offending bolt then try a quick tighten to 'crack' the bolt - it should then loosen...

I have one problem that being, now the bolt which is 12mm, on the left handside of the bike(gear change/nearside) I got the bolt lose with a bit of effort after leaving it over night. However the bolt is now lose, but it will neither undo or tighten.

Its is spinning around inside, I can't get it out, hence can't get the system off. Why is it doing that? I'm totally stuck, don't know what to do. Any ideas? I have some deep prentating spray which I sprayed lots onto it, no difference made.

Umm I guess that means it needs to be drilled out right? Okay so I need to buy some new bolts. Next question is where do I buy the bolts from? I might buy all the ones for the exhuast system as one of the other ones doesn't look great. Sigh. All I do I was lossen it off, how can that make a a thread fubar?
