    Race fuel in stock 13 crf450

    by Chazkline44 » Sat Apr 22, 2017 11:12 am

    So I went to my local race shop to try and find some VP MR12 race fuel and had no luck, they did have renegade 110 non ethanol race fuel instead. My bike is a 2013 crf450 bone stock, I'm assuming with such a high octane that I can't just run this fuel straight so instead of having to remap the bike would it hurt to mix the fuel with 93 pump gas to even the mixture??

    I buy Sunoco 110 and mix it 50%/50% with Non Ethanol Premium if i am racing , or 1/2 gal of Sunoco to 2 gallons of Non Ethanol Premium for practice or recreational riding , i never run straight race gas , just because its expensive , ($8.99 a gallon,vs $2.50 a gallon for Non Ethanol Premium) and i TRY to run Non Ethanol pump gas , because Ethanol id what clogs things up when bikes sit and even when you run it all the time it can still gum things up

    It wont really harm anything in the sense that it will run cooler , start easier , and give better performance , but without higher compression , its kind of a waste of money to run it straight , just 50/50 it and you should be fine

    And when you have that sticky brown gum in the bottom of the fuel tank, methylated spirits swished around in the bottom of the tank breaks it down. Pour on any weeds for their instant death. Much quicker than doing it with fuel.
