i think 40:1 would work, but I run my bikes hard, no racing just trails but the kids use them and sometimes rev high and dont always shift on time. I need reliablility more than anything and something that can take the 100 degree plus weather, it was my impression that the oil helps cool the motor too, I know alot of racers use 20:1 so that was my thought process was if it can be used hard in a race it should be fine out in the trails, plus I want longer time between rebuilds. It was more of a to much is better than too little, and I use semi synthetic lucas oil, its low smoke and i feel the synthetic blend is better and can be ran a little harder.
Recommended jet size?

The absolute best oil that you can use is Castor oil, or a blend of.
Higher oil concentrations will add power and provide the lubrication nessessary to keep the motor healthy.
Any motor of around 200ccs needs 32:1 or better to be lubricated properly.
If you change the oil ratio you need to change the jetting to compensate.
