I would not recommend it, stick with the straight 30W.
30w, 10-30w or 10-40w
5-30w
Most commonly 30W.

Stock motors used 30w.
5w30
5w30
5W30
5w30 if you live in a cooler climate or time of year, 10w40 if you live in a hotter climate or time of year, 30w if you can't decide. Pick your favorite brand.
5w30. the oil fill cap usually will say but all newer vehicles require 5w30.
10-30w. most common oil used in almost every modern motorcycle
