I'm no longer going to be ordering Race Fuel from Klotz since i found a place called Pro Fuels that is 20 minutes away from me and cheaper. They have a bunch of fuels but i am interested in 2, there is 1 called Mark 1, 101 Octane and it is an ethanol free, Non leaded, Non oxygenated fuel. Could i run that stuff straight in my 2013 ktm 250sx that is stock without rejetting? He said it might run rich, but what do you guys think? the other is Mark 2, 110 Octane it is slightly oxygenated non leaded and ethanol free, i would mix this at 50/50 with 91 octane ethanol free pump fuel, How would that work in a stock 2013 ktm 250sx?

Thanks guys!

Try them both, the oxygenated should make more power if you jet for it.

More than likely you will need to rejet for either one. I run VP 110 straight and had to drop down one size on the main and pilot when i started running it compared to what I had in it for pump gas. I rejet my YZ250's almost every time I ride based on air temp and humidity. At very least I adjust the air screw.
