2 cycle motor oil
NO, NEVER! YZF's are four strokes. 2 cycle oil is for 2 cycles...
2 cyc. oil is used in all 2cyc motors.
I don't have a Yamaha blaster.... but I did a little search and found out that it is a two cycle engine. I'm sure that you realize that in a two cycle engine, you lubricate the engine through the oil that is added to the gas, and not through a traditional oil reservoir system. As far as what kind of oil you can add to the fuel to create the proper mix.... their are specially created oils for two cycle use. I know of one Yamaha two cycle oil that was used in a Yamaha scooter I had... it was called "yamalube" ... good luck!

No, you can not use engine oil in place of two cycle oil.
It is a 2 cycle engine and therefore you must use 2 cycle oil mixed at the correct ratio with the fuel.
i believe they have an oil injection system on these engines
