What is the oil to gas ratio for a 1993 Yamaha blaster?

Usually between 32:1 and 50:1 are most common. The mix ratio will depend on jetting, engine configuration, ridding style and premix oil used.

I run 40:1 in all of my 2 strokes mixed with Dumonde Tech DTP. Dumonde did just come out with a new oil, I have yet to try it. Maxima Super M is also a good oil (if you are on a budget)

I would recommend running 40:1, If excess oil is dripping out of the exhaust try 50:1. on the other hand, if the exhaust is completely dry try 32:1. Most likely 40:1 will be sufficient. 16 oz of oil mixed with 5 Gallons of fuel will achieve a 40:1 mixture.
