I've always used Bel Ray 80 or 85 weight Gear Saver oil but the local dealer is out. They did have some Yamalube 4 and 4R oils they pointed me to. I thought those were for 4-strokes. Can I use them in my 2-stroke or is there another Yamalube trans oil I should use?
yes you can use them your bike will be fine most two-stroke owners manuels state you can run gear oil or motor oil ether one will be fine a like the gear oil myself.
