Default Re: 100:1 Mix

Great internet debates that never die:
Best 1911 pistol
Ford vs Chevy
Motorcycle oil vs Car oil
Pre-mix oil and ratios

Here is a nice long thread on mixing 60:1 for KTM 2-stroke motorcycles. If you read it, you will see how running 100:1 is actually making the fuel mixture richer (more gas to air) and that might be why running 100:1 brought out more power on the two identical bikes. Perhaps those engines are jetted a bit lean from the factory. For motors that are screaming, the consensus is to use more oil. I've been running 50:1 on my 200SX, but I'll probably drop down to 40:1 after reading this thread.

60-1 ratio, really? - ThumperTalk
