I got really bad clutch slip on my M600 after using Shell advance full synth

My advice would be to steer clear of full synth on wet clutch bikes. Many have anti friction/wear additives in them now, which won't do a wet clutch any favours at all. I've heard of owners having to replace clutches on jap sports bikes after using certain oils. The additives can contaminate the friction plates making them useless. Good quality semi synth or mineral oil changed regularly, should be more than enough for an 800 monster. It also costs less meaning that more regular changes don't break the bank. I currently use Mobil 10/40 semi synth in the trike which I replace every 3000 miles, with a filter change at 6000 miles.
