can't you use lock-nuts to remove the studs?

Good call Mauri, bit radical but if all else failed well worth a shot.

How about........if you're in the u.k.tonight Take out spark plug fill up bore with water replace plug and leave bike overnight in this freezing weather,expanding water might just push off head!!!..........only joking although I did once pop every core plug in an engine once that didn't have any antifreeze in it. Hope you get it sorted!!

I have no knowledge of this model but one thing did occur to me, there's not a bolt coming from the barrel into the head is there.
If you still have a problem try smashing an old spark plug untill all you have left is the metal piece. Screw this part into the head then get an air line and attach this to the plug, first wrapping a cloth or something around the nozzle to give a seal and then turn the air on. You'll be surprised what a few pounds of air can do. Good luck.

Some ideas here - but follow them at your peril

I would still persevere with the indian rope trick - it worked for me anyway!

[papasmurf]

mustaphapint, it is very obvious from that video it is not the cylinder head sticking to the barrel that is the problem, it is interference and corrosion between the studs and the holes. (It has even dragged a thread off and left it behind in that video.)
I had the same problem on my BMW K75S removing the front mudguard bolts. The steel bolts had reacted with the aluminium of the front forks and made it a solid mass. I had to CAREFULLY drill the bolts out, by hand and by eye. (Realistically it should have been a machine shop or spark erosion,I would never suggest anyone else try it by hand as I did.)

Thank you very much for the tip about the rope trick. I've just used it myself and it worked a treat.

Here in the states we have a miracle product called PB Blaster. Frees anything. A penetrating catalyst Something similar and just soak the heck out of the studs, fill up the stud bores and let it stand a few days. A long drift hit with a hammer to gently shock the ends of the studs..not so hard to deform the studs mind you, so don't grab a sledge hammer. Gentle love taps as someone yanks on the head. That's what I would do.

PB blaster is a rust dissolver.



hence rendering it useless in this case.



as the washers are of a very mild steel they get pinched tight on the studs.



as rust is not the problem.

no matter how much rust dissolver you poor on them it will not get them un pinched.



i am not an advocate of the rope trick, for the simple reason that you’l be forcing on a aluminium rod connected to a piston that has a 1/2 sliced dome.

there in no way to equally distribute the rope/force applied.



i’ll spare you the detail howe i found this out.
