Some people really can't read can they? Maybe my OP was a bit verbose and it wasn't clear what I was asking at first, but nobody suggested the oil SHOULD be checked when cold. It was checked when cold to confirm my suspicion that I was over filled.

Anyway it was indeed overfilled.

Pissed out the dipstick under pressure when I unscrewed it and that was about a minute after I switched the engine off. After it stopped pouring down my radiator I syringed a further 150ml out using a plastic tube before the level dropped to something acceptable on the dipstick. Thought I'd better have a look at the air box and that was swimming in oil too.

Now I know there was a real problem I'll name the dealer, it was Motorcycle Mart in Kidderminster. Probably some 16 year old YTS monkey that doesn't know the difference between wet and dry sump, who filled it to the top of the dipstick whilst cold.

Thanks Pleiades for understanding what I was asking and your advice.
