As many have said you would need an e85 compliant fuel system. You want to replace your entire fuel system to save a few bucks on fuel? Not to mention you would need an ECU to run your new injector(s)...
Again fuel costs, MPG, is a factor with cars not so much with MX bikes.... I may could see it in a street bike...
I would take the 450 injector and roll a 450 under it missing its injector, install ,power problem solved
2 reasons guys run out of gas at an outdoor national. Highly oxygenated fuel, and big bores. Both use far more fuel.
Alcohol runs great. It's not hard to remap for it. Learn how to pickle an engine.
And use some 2 stroke oil that mixes with alcohol or something like this.
E85 is marginally cheaper here, and by the time you go out of your way to buy it, it's not a bargain anymore. And after the mileage loss, it is really NOT a bargain at all for street rigs.
Liter as reg fuel. That is why the mileage sucks. Yes it runs great but if you need 25% more to finish a moto where is that storage coming from? Offroad even worse.
Well this took off a little bit more than I anticipated...with some typical vitard comments.
If you had any experience in running ethanol, you'd know that shit leaves the inside of the engine spotless! Better than most race fuels.
The "right gas" is dependent on what is done to the motor and what octane it requires. Clean E85 has been proven to make more power than the majority of VP race fuels...With exception of MR12 and crazy shit like that, but that stuff is $26/gal
There is more energy in E85.. because you need to burn it at 8:1 instead of 12:1. Your burning MORE of it to make the combustion process work. Fuel is fuel people..yes gasoline containing more BTUs per lb, but you need to keep apples to apples here. Methanol burns at 4:1 for max power, so your burning WAY more and getting more BTUs.
Alcohol, which is what is considered OXYGEN in any oxygenated fuel, has this neat little thing called latent heat dissipation. As alcohol evaporates it gets cold, cooling the intake charge and making it more dense.
E85 is a good fuel and would work just fine in your bike if you got it mapped right.
The motor in your bike works in the exact principle as your car. This isn't rocket science..
Alcohol is just a headache for every day use.
IndyCar doesn't use methanol because it makes more power.
I use ethanol every day in my car.
Honestly, the 2 main draw backs for me anyway are the reduced fuel economy and the need to change the oil a LOT more often as it gets contaminated with ethanol pretty damn fast...which are actually pretty minor, im just a lazy ass.
The main advantages for me are the cost #1 its ~$1.90 per gallon vs $3.00 per gallon of 93. and E85 is 105-110 octane. Race gas on a fking budget...it's amazing.
dirt is for racing asphalt is for getting there
well,
alcohol is for drinking ,gas is for getting you to the liquor store
Pit Row
It's never caught on out here really. And usually the pump is off to the side somewhere. And who knows how old the shit is. They don't have a big turnover of it. Other than that, if you want alcohol, you just gotta buy pure methanol at one of the local hot rod shops.
There are only like 50 stations in all of Northern Cal with it. I can't even remember the last time I saw a station with it.
We literally had to drill the needle and seat, drill every fuel orfice in the carb and make a needle. I showed up to 1 race and people just complained about burning eyes and obnoxious smell.. the bike was gnarly. After about 10 minutes the nitro methane separates in the float bowl and without going into a huge story, my bike ran away.. it was dieseling when I started it and we couldn't shut it off. Had to yank the carb out of the boot, pulling the plug wire did nothing. It was embarrassing, and people pretty much knew i was cheating.
I had the bright idea of running this stuff at a national qualifier to get a good start, but the idea ended quickly.
I'll say it one last time, it's easier to buy pump gas and work on going a LITTLE faster through the ruts or corners. It's a lot cheaper too
Call NorCal KTM, talk to Eric the owner and he will give you some info if you really are interested.
Not just shit stirring for the hell of it.
The big improvements in power running E85 are on forced induction set ups.
This idea is a big dud for a 450F to gain 1.5 rwhp imo unless you are hill-climbing or something.
