Along with my Rocker C a nice new Danny Gray seat came with it. It's only now I realise why it wasn't on the bike. Two of the torx screws that hold the pillion bracket to the frame have had their heads stripped in an attempt to get them off. Any suggestions would be appreciated. One of the heads is a real mess. Looks like someone has taken to it with a chisel. 

Go to a nut and bolt shop and get some stainless ones

Either:
- Drill a hole through them and then try a screw extractor to remove them
- Weld something solid to the head (like a nut, but weld in the middle of the nut so you can use the outside with a spanner). The heat may even help free up the thread.
- Cut a slot in the head with a dremmel and then try using a standard flathead screwdriver (this has worked for me in the past)

Or try and knock In a larger torx socket or hex Allen key

Thanks guys. I had a bad experience with an easy out once and swore off them. So I will give the welding a nut a go. Torx screws are a god awful invention and will change them all to Allen heads I think!

If there is enough room try a vice grip first before u get into welding shit on.

No room for vice grips. After a little bit of research I've grabbed some Irwin bolt removers, there designed for hex bolts but will work on round torx screws as well. Will give them ago first.

Impact driver with a good torx bit (kincrome or better) will do it, or get a dremel, cut a line in the head and use a flat head screw driver. I wouldn't be welding shit near a seat.

I agree Bonkerz, welding is my last option, would remove the seat first, probobly take it to a pro as well.

hit it on da head  & on its side if ya can a little gas flame , just in case it might have some loctite on it like perthog say's 

Thnaks guys for the good suggestions. Took the bike down to mechanics near me. Had the two remaining bolts out in seconds. Wouldn't charge me for it. Danny Gray seat is fitted and looks and feels much better than stock tractor seat!

This happened to my forty eight . I cut a piece of rubber glove. Put it over the tool bit then stuck it in the hole . Turned and kablamo it loosened up. A bit late i know but happy to hear you got it out

I have in the past gotten the next size up torex and wacked it in with a hammer. Once its well and tryly in there the bolts normally just come out easy!

I recently had the same problem while fitting a backrest
the screws on the chrome bracket were tight as and burred
I managed to cut a slot in them and the used a chisel in the slot to tap it til it moved slightly
breaking the hold, then grabbed it with a stilson wrench.
bit of messing around but eventually removed them successfully and without damage.

last option would have been to weld a nut but I really didnt wish to do that as it would have damaged the chrome work

Stevef what route did the machine shop take to solve your problem? I had a sheared bolt in a c*@t of a spot and took it to an engeneering joint and he used a sparker to zap it out till the 1/4mm of thread that was left could just be bent away with a scribe point. He also charged me next to nothing for well over an hours work (closer to 1hr 45min). In retrospect what I would have done would be to drill a hole as far as possible and then sink a snug-ish old round steel piece that can be heated with a touch till red hot and then pull it and chuck the easy out in and see how that goes as mentioned above the heat will help expand the seal and melt any loctite that may be in there. I've had some bad experiences with easyouts snapping on me in the past (thus my trip to the engineering joint) but have found that there are some pretty good ones out there now that will have an even better chance with the heat. Glad to hear that it's all sorted now though. 

NR. 

This info is for stripped hex bolt, but would work with stripped torx bolts as well ... There is always a few ways to skin a cat, as in advice given in above posts.. !!!!

 

Jesus Christ!!! Was there loctite mixed with ramset801 and superglue on a spot welded thread or what?!?!?!?! Man that's one hell of a lot of torque for a seat bolt!!!! Lucky you didn't have to hook a chain to a tow ball and gun it by the sounds of things!! 

Yeh have now replaced those bolts with stainless hex bolts and just a dab of blue locktight instead of a litre of red!!!!

You got me thinking I might do the whole bike now where possible. Thanks for costing me more money and work stevef ????

Exactly Ballofski. Any Perth guys that are looking for replacement fasteners, Searles in Willeton (High Rd behind Bunnings) are great. Mild steel, stainless and high tensile they have it all in imperial. You can buy one bolt or 1000 bolts. Can't recomend them highly enough.
