Issue arrises from using non wet-clutch specific oils, most semi-synth / fully synth car oils have moly grease and other slipper aditivies in them to reduce engine-wear improve mpg but it causes a clutch that runs in oil to slip

How often can you wait between changes if you use fully synth?

Im not sure, I don't leave it in there any longer than i would a semi, just peace of mind that ive put the good stuff as the bike is at high rpm all the time. I know cars run long life fully synthetic, so it must last longer.
