Racing Fuel
Can you run the high octane racing fuel in a 1996 Kdx.
If you had a choice to date supermodels for the rest of your life or ride dirt bikes, would you choose a 2-stroke or a 4-stroke?

Shure, but why bother.

Re: Racing Fuel
Pros, it burns clean,
Cons, it costs way to much money, it burns hot, it costs way to much money.....race gas is a waist in a kdx.

Re: Racing Fuel
I agree that burning higher octane than needed is usually much more expensive and therefore efficiently lightens the wallet.
But why would it burn hot?
Honest question.

Re: Racing Fuel
It wouldn't burn hotter, in general. Fuels are an extremely complex subject, and burn rate, engine temps, charge cooling, throttle response, etc etc all depend on fuel blend, not octane. You can have two 100 octane race fuels with dramatically different characteristics.

Re: Racing Fuel
maybe if you were to bump the ignition timing way up you could utilize a little more from it
on a side note, it would smell amazing!!

I do love that smell.

Re: Racing Fuel
Unless your going to cut the head for race fuel you wont see any gains. As for the smell, maxima 927 has a very simular smell.

Very true, a compression bump is most likely needed to take any real benefit.royadams wrote:Unless your going to cut the head for race fuel you wont see any gains. As for the smell, maxima 927 has a very simular smell.
Just throwing more timing at it doesn't do much unless you were limited by detonation previously. Many engines are setup running near MBT, or maximum brake-torque timing (or minimum best timing, or 13 other names it's often called). Advancing the timing further simply decreases power. If an engine cannot reach MBT because of detonation on a certian fuel, then yes, running better fuel and throwing more timing at it can help. The KDX is a very mildly tuned bike and simply doesn't require "race" fuel.

Re: Racing Fuel
I can see a major difference when I run premium then regular. I put regular in my bike last summer and it seemed way under power.

Placebo, unless it was knocking or some seriously bad fuel.

Re: Racing Fuel
So regular or premium shouldn't make a difference? I've used both and have never noticed a big difference, but I tend to go for premium.

Re: Racing Fuel
Regular is not a good match. The compression warrants premium, but anything more would be overkill.

Re: Racing Fuel
The lowest octane to avoid pre-ignition will make the most power for whatever static compression ratio. It will inherently run richer and therefore feel even doggier just by pouring it in the tank. Race gas will however provide better throttle response, and possibly some more off idle pull. Most who play with gas will just run a smaller percentage of it cut with pump, or use tolulene to get the same grunt. Be careful however, you must tune to take advangtage (lean the mixture), and don't go back to straight pump after the fact without fattening the jetting back up. In summary, Unless you're in the practice of anally tuning your bike to stoichometric A/F I wouldn't bother with it!!

Re: Racing Fuel
Needing to lean the jetting when going to race gas is a very general recommendation. There are a lot of oxygenated race fuels, as well as plenty with specific gravity less than pump gas.
It all comes down to testing with what you are running and tweaking as needed.
