gas oil mix

[ilovemybike]

Hey i just got my 87 kx500 sunday and i had to buy some 2 cycle oil at an ace hardware (the only place around where the seller lives). so the question is should i finish off the bottle, or switch to the yamalube semi synthetic??? i dont know what kind of oil he used when he had the bike, but from what ive read on here is to use one oil and not switch is this true?? any info would be great!!!
Thanks

I like to stick with what I know works for me.  I just bought a CR500 ('97) to go with the KX500 ('04).  The guy was running castor oil, the kind that smells like the gas we ran in our model airplanes.  I'm going to finish running the gas that's in it, then I will remove the tank and pour in about 2 cups of my gas to rinse out any remaining old gas.  Then I will run the Bel-Ray synthetic oil mixed at 40:1.

Yamalube 2-R is one of the best oils you can run in a 2-stroke engine. I ran 32:1 in my 500 with great results. Piston/rings and power valves were spotless every time I torn the top end down. But everybody has strong opinions about the oil they use. Currently running Yamalube 2-R in my 05 YZ250 and I'm getting the same results.
