WD40, is not a penetration oil. A liberal squirt of of Plus Gas or similar would be far more effective

...now you tell me

Thanks for replies.

The bike is a 650 K1, first registered june '03. It had done 7k seemingly dry miles, was immaculate - and handled like a drunken pig, which probably accounts for the 5 previous owners!

I got it in sept 2006 and sorted the handling by aligning the wheels properly and more importantly fitting Hagon progressives and Mich PR2's(which are still on and got tread left)

Now it's done just over 16k miles and been through two riding winters. The nuts look OK, if a little bit rusty. I've got a 6 point deep impact socket which fits OK. I don't really need to take the nuts off but being seriously obsessive, I thought I ought to check them out sooner rather than later

cheers.

Well to me it sounds like your will come out much easier then mine did, as it just looked like a brown lump.

grinch,

did the rost ice help?

It's worth getting some real penetrating oil for this sort of thing, WD40 does all right considering but Plusgas will shift bolts WD40 won't touch frinstance.

Did you get the stud out then?

Just checking prices of plus gas.. Should I get the 250 ml aerosol for about £4 or the litre tin for about £7? Spray on or brush on? I 'won' a 1/2 pint can of releasing oil when I was an apprentice; it was called Releasol or Lusol or sth like that. Probably used it 4 or 5 times in 35 years. Best get the squirty container?

I got a couple of the wee aerosols, still on the first... Like a lot of good products you end up using much less

Unless they come out easily at the very first attempt I wouldn't even try to undo them, get a hacksaw and cut through the nut along side the thread of the stud - it takes a few minutes only. Spread the remaining bit of nut with a sharp tap, easy with that of course, and it will come off very easily.
If you don't have a die, get a suitable nut and put the saw blade through the hole, cut three or four full thread depth notches into the nut and use it to clear/trim the thread of the stud with.
