Yeah page 4-14 of the Top End section in the manual. There are also compression values there that should be what the motor puts out.
Head gasket is an engine out job for sure, i know one or two members here can do them in a day or so but thats going to depend on your experience and tools. Taking to a mechanic you probably looking at a couple of hundred qud at least. You could have yourslef labour cost by taking them the engine.

Re: Redex causing issues ??? Or just a coincidence ???
Seems to be fixed !!! thanks for all the help.
Checked the compresson ratio (after finally tracking down a 10mm compression tester (QB bikes in Quarry Bank - god bless em) all 4 cylinders were firing out at 100 psi - which is just within the limit ! so dont think its head gasket - thank god. Figured the compression would be higher in reality, was trying to get bike warmed up but next door neighbour come to ask not to make noise as they had a "dieing child trying to sleep" suffice to say i didnt keep the engine running, so figure compression would pos be a bit higher ???
Anyway - started to look around radiator etc.. for issues, giving the fittings a good yank, did it to the thermostatic fan switch, and it just came off in my hand ! had completly corroded and one of the plugs had snapped off. went to cradley for a new one (£34 with the 10% members discout - nice one baz) fitted it, and drained coolant. Took the bike on a 10 mile razz and no issues at all with overheating, stayed within the first two white lines, no issues
weirdest thing of all is the odd rattling, that i thought was cam chain (between 4-5K revs) has now also disappeared. Dont know if this is anything to do with the thermostatic valve - or if its a loose bolt or similar on fairing - as i went out on it yesterday without re-attaching the fairings !
so thank good its all done
ready for bulldog in a couple of week
thanks all, especially baz and rob for all the input / help

hmm, interesting you mention that. Dont forget to check the tank cover at the front of the tank. I recall having the bits at the side vibrating against the tank, used a bit of blue tack between the two and it sorted it.
