Took the top yoke off and, on another members experience, expected a fairly simple ignition barrel removal using an anti tamper torx bit. But no. The bloody thing is held in with a headless bolt. How do I get that out without damaging the yoke?

If you're careful, a small cold chisel and hammer.. Or drill the head off.. or drill a hole big enough to get an easi-out down it. Im my experience they're either just right or too fookin tight.. They start out life with a hex head on them which snaps off once done up. Clever idea, but can be a PITA to get off. Should be easy now you've got the yoke off.

If you use an easy-out, drill the pilot hole with a left-handed drill bit; that sometimes helps to loosen it.

If such a thing exists..

Sorry mate, as I explained to you my ignition barrel was held in by 2 anti-tamper torx bolts which I've since re-fitted on to the original top yoke. I didn't have any headless bolts to deal with, apologies for misleading you but I can't explain why my bike has these fitted and yours doesn't?

Got a set of said left hand drill bits, they tend to work better than easy outs.

Had a look.. And ye learn something new every day! Seems they come part of some stud extraction kits..

They do; I've used them. E.g. http://www.phantomdrills.co.uk/ShowProd ... ?CatID=516

You just need a left hand drill to go with the bits now then.

.... I think that everyone is trying to make this faaaaaar tooooooo complicated.

It's easy.


Cut a slot in the head of the bolt with a dremel-type-thingy and unscrew with a flat-blade screwdriver.

That's how I did it anyway

Sorry Will, you slipped in ahead of me.

Learned the LH drill trick from my Dad, who'd had to learn such things in WWII

Back to the OP: would it be safe to apply some gentle heat?

...... and they're still trying to make it too complicated ......

Then all you need is a left handed drill.

Nooooooooo - a Dremel-type-thing ........ FFS !!!!!

To go with the left-handed hammer
