I picked up some VP C12 today from the one little shop i know. For anyone that doesn't know C 12 means 112 octane. He told me it is save to run in my yfz that the newer four strokes can handel it with out having lots of engine work. He told me to just mix it 50/50 with some of the 92 sheetz gas. I have the Cam mod, Curtis sparks full system, k&n, and it's rejetted. You guys think it is safe to run? Also i payed $8 a gallon you think that's a good price for it?

Yes, the C12 means 112 Octane.

$8 per gallon is what i'm used to seeing.

Not sure on safety, probably fine with the 50/50 mix. I'm used to seeing people run it straight, but most of my buddies all have serious, high compression, motorwork...not sure about a hardly worked motor.

i ran that stuff in my 400ex when the piston was stock (9.1:1) and it ran fine. smelled better but that was it.

like said its pointless to use in ur motor. you actually might even lose a small fraction of power

and $8 is kind of a rip off, but that is average price if you buy it by 5 gallon cans. I pay $6 a gallon buying 55 at a time....

Where do you get it at??

The local yamaha store near me sells C12 for 10 a gallon:eek2:

man... if your bike is stock, i would probably mix like 1 gallon of race with 4 of pump, or at most 2 to 3... other than that you are wasting some serious money... thats the beauty of a stock bike...

It would be safe to run 50/50 but my question is Why? It won't give you any power gains

My buddies stock 450r with White Brothers E2 ran best with a mixture of leaded 110 and 93. I could even tell it ran better whenever I would ride it. That is what he runs in his LTR now.

The dealer around here tried charging my buddy $70 for a 5 gallon can of C12. So, he gets the 110 leaded stuff from Sunoco for 5 bucks a gallon.

no point in running it in a stock motor. You will not gain anything from it, but will loose money lol

I ran VP c 12 in my 250r, it had a fully built motor. And i was paying 5 bucks a gallon he he :devil:

Without a high compression piston you are wasting your money!

The guy talked me into it so i payed $8 for a gallon just to try it out. I don't plan on buying it all the time way to much money. But seense i bought it i wanna run it. SO what would be a safe mix to run it with and will it do any damage to my engine? The dealer said it would make a difference and some of my friends run it and say it does to. Probley won't make any seense my engine is stock. But all i wanna know is what should i mix it to and is it safe.

vp c12 is 108 motor octane not 112 octane and a lot of people mix pump gas with it 50/50

C12 is only 108 octane. Yo will not notice anything by running it in a stock motor, and no it will not make less power. It will in fact make more power, but very little. There is more to fuel then just the octane, There is its burning speed, energy value, and cooling effect(which really does not matter that much). I have a 450r with a 12:1 comp piston and a stage 2 hotcams, and I run it on 93 pump gas. It runs fine, but i started to look into race fuel but the place that i was going to get it from wanted like $11 a gallon for it. I have also been told that when you run a leaded fuel, it will make your motor last longer because the lead makes a cussion for the metal, but i do not know how much I beleive that.

LOL, im just too lazy to go to the gas station and fill up my jugs, so thats why i use C12 in everything:) Ive got quite a few drums around here too. Its kinda funny, you can always smell me when im cutting grass, the neighbors say it smells like they are at the track

like already stated, you will not get the most out of it unless you have other engine mods than you listed. High comp. piston, different head mods, porting, etc. Most guys will run it straight, but honestly for your situation pump gas will be suffice.

run it straight (well with klotz mix) in my blasters every tank love it compared to pump gas but then again mine is bored .80 over with a high comp piston and head mods

well i have run it straight in my predator thats bone stock.... i can say that it definately isn't worth it, i only ran it because i had a friend who gave me a few gallons for free so i've just waited till it was bone dry then put a couple gallons in for the hell of it. i can say that my predator did accelerate a little faster but its definately not worth the money without other mods.

now from what i've heard in a few different places U4 does help but its so expensive its not quite worth it either by the sounds of it

In a stock four stroke running C12 50/50 will give you better throttle response and cooler operating temps. Running it straight you will lose power. U4 and U2 are oxygenated not C12, with C12 you really shouldnt have to change jetting. If you are on a completely stock bike with U2 and U4 jetting from the factory should be close, if you have any changes you will need to jet up!

i ran it in my 416...and it ran great....im thinking about mixing it 70/30 in my 440...i rebuilt it with less compression.....but the higher octane seems to make it run cooler.....and as it is now.....she gets really hot......you should be fine.....just dont expect to see any real power gains from it.....until you get into the motor anyhow!
