OIL MIXTURE
BigGreenMachine:
More oil will give you a better ring seal meaning more compression and will also reduce friction...both of which will give better performance.
kaw rider:
i'm shooting for 8:1 oil ratio.
FactoryPhil:
Let us know the results

I bought my KX500 new and was nervous about not using enough oil. I simply stuck with the factory 32 to 1. After two hundred fifty gallons of fuel through it, I took it apart to look at the rings and bore. Everything looked like new, but was a bit too oily to suit me. So I just went to 40 to 1 , plenty of oil for me. I have been thinking of dropping to 50 to 1 for next year. Now that the bike is no longer new, I am more confident to take risks.
Every one has an opinion and this is mine. John

Your motor will also run very hot. Oil burns way hotter than gas. Also, more oil means more spooge and clogged powervalves, along with carbon buildup, which also leads to overheating.
I ran 50:1 doing dragracing sometimes holding WFO for 1-2 minutes on the flats running a PVL which boosts the RPMS up about 20%. My motor ran cooler and jetting was easier after switching to 50:1 over 32:1.
