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
Dane
