oil type?
20w-50 seems a little thick for a bike with decent bearings in it. Thick oil is usually reserved for worn out bearings or bearings with huge tolerances. Thick oil is just harder to pump and fits into less places (like your wrist pin and cam bearings). Unless your manufacturer says to use 20w-50, I'd stay with 10w-40.

He is talking about a 2 stroke. The 20w-50 oil is only for the 5 speed tranny not for engine lubrication,the premix or oil injection handles that job.

Yeah, I was thinking 80w-90 for gear boxes, but I didnt know enough about 2-strokes to comment. I know in cars and trucks, it used to be regular ole 80w-90 gear oil in the diffs and manual gear boxes. Now they've changed to ATF for the manual gearboxes,,, still 80w-90 for diffs though.
