How deep into the head is the pipe I assume it locates in a bore,probably corroded now.

the pipe is a push fit into the head about 19mm with a o ring on the pipe ,,and using wd on the bolt made no difference on mine i ended up giving the bolt a whack down with the biggest hammer i could get in there ,then it came out ,,now its a stainless cap head with a spring washer and copperslip on the threads ,and a new o ring ,,,,hope this helps

Steve,
Cap screw removed easy enough the main prob is the pipe must be corroded into the head might need to saw it off yet

no need to saw it off, it will have jammed in there with corrosion ,just try and get some movement on it and it will come free,,it will be tight if its been in there a long time , i had to get a bar thats fits inside the tube and work it back and forth to get some movement on it and then it came free ,,, it will fight back though just make sure you win !!

Steve,
Gave it a good seeing to and your right I won

checked all the valve clearances and after all that their all within limits so you could say a waste of time but at least I know clearances are ok thanks for the input.

cut it off, buy a new one. The pipe is obviously dry as a nun's nasty.

When you go to install the new one, a THIN wipe of vasoline or high temp grease on the tube + fitting. Should make it fine. but THIN remember, you only need enough to wiggle it on, no so it shoots off soon as you start the bike !

And a ziptie if you wish below the ribbed bit so it wont pull off.
