It sounded like such a simple job! The bike was suffering from a lack of compression, though once running the performance seemed good enough. I guess over time this could have deteriorated without me noticing. Anyhow, I thought it would be as well to take a look at the decompressor, and so set about removing it. Like a twit I pulled the small split pin thinking this would help get the cable out of the way. I heard the clunk and realized what had occurred. That's what led me to remove the cylinder head. I had done this job successfully a couple of years ago while attempting to cure an oil leak from near the pushrod tube. At that time I assumed the original gasket to be at fault and so got a new composite gasket from our hosts, and fitted this on re-assembly, keeping hold of the old copper gasket which was in good condition "just in case". Presumably by using the original copper gasket this time round I shouldn't have a problem with the fire ring? Or would it have compressed during it's time in service. Thanks for all the enlightening comments so far.
