Any tips on removing the two security bolts that hold the ignition switch to the top triple clamp?
I'm thinkng i'l have to drill them out to remve the ignition then pull what's left out with vice grips.

Sugestions?

I think you got it

yer the drill them out method is the only way i could get them... such is life really

Unfortunately mate as the others have stated you have to drill them out.

When i done mine i used a pillar drill so you can drop the rpm,s right down on it and get 100% accuracy, hand held drill is a bad way to go as it takes alot of downwards pressure on the drill to get through them and you can only achieve that on a pillar drill.
I reckon they made the bolts out of feckin granite or something!!

Once the heads come off its plain sailing from there on.

My mechanic mate does these all the time and his technique is using a long socket that just fits in the hole. He then taps and turns at the same time. Use an impact driver if you have one or a pin punch. Good luck.

Dont forget to post some pic's when its all back together

Besides the fact that they are made out of "feckin granite or something" ( ), they're also bonded in there with the stuff they glue the space shuttle together with. A little heat has been know to help break it apart (no disrespect intended to the Columbia astronauts) but I'd use a hot air gun and not an open flame.

let me tell you a little something max about that space shuttle glue as thats what i build for a living.
once that stuff has air cured for 48 hours its not fun getting it to unstick again, heat may after a long long time do it but theres only one thing we use in the trade and thats a nasty little substance called ardrox.
that stuff is the devils work and will eat its way through anything if you spill it including titanium!!

available at the space equipment section at Bunnings?

Interesting.

Ardrox, what you need to get out that nasty little bolt AND whatever it's attached too.

Thanks for the tips guys!

Now if I could just get back to my garage in Brisbane for a while I can get it done.
p.s The hotel staff weren't happy I changed the entire front end in the middle of one of their rooms........ (Who'da thunk it)

I think I welded a nut on top and unscrewed them.

It wasn't as straightforward as that might sound though.
