Oil

Looks like oil, smells like oil, tastes like...don’t know, didn’t try. Should be good stuff. My experience with past bikes is that motorcycle specific oil is better for the wet clutch. Just make sure the weight you get is appropriate for your conditions.
 
Around here it should be 10w-40 full syn. Did use 15w-50 for couple of years. Harleys use 20w-50 mineral oil.

My 1990 Suzuki DR 650 likes (Exxon)Mobil Delvac 15w-40 mineral truck diesel oil (or is it semi-syn???). Go figure....????
