Which VFR750? RC24, RC30 or RC36?

If so then that might just be water vapour. My GSXR does that when its been sat for a while and I start it up. My SV used to do that on cold mornings to until it had warmed up.

White smoke is normally water vapour, blue smoke is oil. Well in my experience anyway. Not sure what the cause of the oily smell is though.

maybe your right fizz, i wont get a chance to cheack again till friday but it was only running for a few mins. thing is it started up fine then became smokey ( smoke didnt linger though )

Early or late RC36? (not that it really matters, I'm just curious now).

Anyway white smoke is normally coolant, do the usual check for oil in the coolant and mayonnaise in the oil. Could just be the amount of condensation in the exhaust though.

WRT leaking gaskets only head gaskets to worry about, cylinders are cast into the 'block', taking heads off isn't that big a deal and can be done with the engine in the frame. No cam chains to worry about which makes life easier.

ill run it for longer next time, probly changed coolant out anyway and check to see if the thermostat has had it...could just be a loose sender unit.

ill report back tomorrow actually as im home for lunch.

If it has a rattly clutch that goes away with clutch in it most likely needs balancing.

No, the carbs. The crank doesn't rotate at a constant speed at low rpm, when the carbs are out I think it accelerates and decelerates quite harshly causing the clutch to rattle.
