2012- ? Fuel injection MPG

We all know that these bikes are gas hogs, but does anyone know why? im getting about 25mpg right now on my 2015. I would think it would be a bit better than that being that it is injected vs carbureted. Thoughts? 

That is bad ours Wrs Carbs/or Inj  30/35mpg.Sometimes deep sand as bad as 25mpg.

After riding my 2015 WR450F 3 times I ordered the IMS 3gal tank. I changed my mapping and I'm getting somewhere around the 30 mpg to 35 mpg. If your running a map that is way up on fuel delivery >+4 it's going to drink fuel. The power feels great though.

What map are you running? I havent changed mine yet, still running what came with the comp ECU.

when I'm going for MPG / distance rides I run the "Bush" map which is lean and a 15t front sprocket. I can get 45 MPG if I'm easy on the gas.

I'm getting low 40s with 14-50 gearing and dual sport riding using the Aussie hard pack map

Looks like I need to try the Aussie map out. I ran 26 miles of road / forest service roads with a small amount of single track a little over a week ago with some buddy's and it burned a gallon.

I've been running the Motocross and Bush map and both are good though I think I like the Bush Map better.

Gas milage is equated to what happens with the terrian and or your wrist to a large extent. Where we ride I can get as low as a couple of gallons in 35 miles and that would be considered good milage in this nasty terrian with lots of monster hill climbs. That's on a 16 WR model.

If you want to get good milage obviously watch your wrist. I would also think a bit more advance and keeping the fueling low would help some. That's if no pinging is present and running premium fuel.

The amber led comes on at ~50 miles since last topping up.

I can squeeze in 5 L it that case.

 

Hence my '12 WR450F does 37 mpg,

e.g. I'd run dry after 70 miles.

(short rides, on road, this spring)

I need to get my hands on a tuner and try some different tunes. Local dealer said they could do it but at two visits to them the tuner would pay for itself. Not worth giving them the $$ in my eyes.

Numan,

I have a GYTR Power Tuner you could borrow anytime if you're anywhere near the Wenatchee area.

Ive got the 2012 model and while the aussie and bush maps definitely give it more punch, the standard map setting ie all the zero's is the most fuel efficient that I know of. I know a few fellas with them and they all say the same thing. I put an aftermarket exhaust on mine which gave me the punch I was looking for and then went back to the standard setting, because I generally do 140 -150 km rides.

So far, every FI bike I have owned has terrible MPG for the first 5 to 10 hours.

 

I believe the ECU's are programmed to be overly rich for a certain number of hours of 'break-in'.

 

My BETA 430 went from 20 mph to nearly 40 mpg with no changes to the bike, and at the same riding location,  at about 11 hours.....same with the 350 XCFW and the 500XCW.

From the day I bought my wr450f it has drank like a thirsty camel, and 150 hours in nothing has changed.

My 2012 WR450 averages 28 MPG (8.5L/100 Km's). My old WR400 had better range, and that was with a YZ250 tank on it.

Same as everyone else.. mine is also a gas guzzler. 2012 running the fmf map with powerbomb and slip on.. 35 mpg from supermoto duty... 

 

Gonna try a zero'd out map to see if the gained mpg's outweigh any punch I might lose. On a side note- it'd be nice if the low fuel light actually came on when I was low on fuel. A lot of times I find I still have a little under a gallon to go before I'm really empty.

As far as I'm aware the fuel light comes on when theres 3 litres left. So if youve got the stock tank thats not far off half full anyway.

Last mileage check on my 07 yielded 57mpg.

 

Easy trails and 45mph on roads.

 

Did an 83 mile ride on mostly trails a few weeks ago. 3.6 gallon tank was above the half way mark at the end.

 

Carburetors may be old school but sure do get good mileage.
