fuel help

Ok so I've got an 05 450r and it has a 14 to 1 compression piston and the main thing I'm wondering is what gas should I really be running I'm mostly just a trail rider. I have been running straight 112 but its getting pricey just to ride trails. Thanks guys hopefully someone has some good input :)

I wouldn't go any lower than 110 with 14:1. With race fuel, and gas in general as high as it is, I would opt for 12:1 and just run premium for trail riding.

Oops sorry I musta hit the wrong button I ment
13 to 1. But is that pretty much the same boat? I have actually had this quad for about 2 years and I thought he told me he would mix it half race and half 92 but I really don't wanna screw up my motor.

I wouldn't feel comfortable running pump gas with anything over 12.5:1. The power difference between pump gas/12:1 and race gas/13:1 is going to be very minimal. If you were racing it would be a different story. For trail riding, it's just not worth the extra cost in my opinion.

Ok so basically should just stick with the straight 112 unless I want to put a piston in is what your saying?

I know lots of people that have cut their race fuel with premium with no issues. I always preferred to run straight race fuel. But at that time, gas wasn't near as pricey as it is now.

Ya well I may just try and go like 3/4 race and 1/4 92 just to save some haha really for all the more I get to ride any more I shouldn't worry about being cheap but this day in age you gotta save all you can.

I'm running 50/50 (C12/91+ pump) on my 13:1 piston.. No detonation, and it runs like a champ.

you should be able to run run pump with like 1/4 race if you had to. no detonation is going to happen. two years ago i didnt run race gas at all unless i raced and i had a 13:1. if it makes you feel better then go 1/2 race, but especially if your racing trails, you can run mostly pump.
