So much for full main dealer service history!! The tech monkey doesn't know what a dry sump is.

Thanks. Any idea approx how much I need to drain? Does your oil level show at all at the bottom of the dipstick when cold? What I used to do with the XT600 when I did an oil change was measure the amount of used oil I drained then put the same amount of fresh oil back in.

Does it have a tendancy to piss up the breather into the airbox when overfilled? If so I'll need to check that too now.
