Best bet is Rotella 15-40. Stuff is super cheap and works fine. If your clutch drags or bike is difficult to find neutral with engine running drain the Rotella and use it in the lawnmower. Switch to automotive ATF dextron lll non synthetic trans fluid. Stuff is the treat for old sticky clutches and it helps the gearbox shift slicker than greased weasel $hit. Also very inexpensive. Change trans fluid at 4-12 hour intervals of run time for best service. I change mine every 4 hours just to be super fussy.

okay thanks, when I bought the bike used I got Motorex SAE 15w-50 4T oil. Would that be safe to use considering its a 2 stroke? Sorry I just don't have the best knowledge of this bike yet. If its not any good I will use your recommendation. Thanks.

Sure. That's fine. That is the factory recommendation for those bikes. The Motorex is a bit pricey but it's good stuff.
