drewpy302 Posted September 22, 2017 Share Posted September 22, 2017 So, I got an FZ-07 a couple weeks ago for my first street bike of my own, and I love it. I just had a quick question about the mileage. According to the bike, I've been averaging between 12-13 mpg since I got it. I've been riding it pretty hard, but that still doesn't seem right at all. Plus, I got around 100 miles on the first full tank I put in it, running 93 octane. I've searched the forum, and it doesn't seem like anyone else has a reading of 12 mpg. Is there maybe a way to reset it that I don't know about yet? Link to comment Share on other sites More sharing options...
chiburbia Posted September 22, 2017 Share Posted September 22, 2017 12 is horrendous.. even when I'm getting on it I still get around 4X-5X as the lowest. Are you watching on current mpg or long term averaged? Link to comment Share on other sites More sharing options...
shinyribs Posted September 22, 2017 Share Posted September 22, 2017 12mpg won't get you 100 miles to a tank. If you used the entire 3.7 gallon tank at 12 mpg you would only be able to travel 44.4 miles. I flog mine pretty hard and stay around 42-45 mpg. That's with me staying at half to wide open throttle and using 75-90% of the rev range. Unless I'm straight up highway cruising. My mix of playing/flogging and cruising is 50/50. Any chance you've somehow got it reading metric measurements by accident? Maybe it's reading liters/ 100km or something? Link to comment Share on other sites More sharing options...
afatrat Posted September 22, 2017 Share Posted September 22, 2017 It says how to reset your average mpg in the owner's manual. I think you just cycle through the display and with the average mpg's blinking, hold the right button until it resets. Either way that read out is rarely accurate for me. I just calculate it at the pump. Ringing it out I still get 45-50 mpg ('murican). Link to comment Share on other sites More sharing options...
mecmar44 Posted September 22, 2017 Share Posted September 22, 2017 The lowest that I've seen has been 52. I use mine mostly for commuting ~40 miles a day. I can usually get upwards of 200 miles out of a tank. Link to comment Share on other sites More sharing options...

Metric would be ~13km/L = 30mpg, so that's believable if really getting on it and never cruising. Link to comment Share on other sites More sharing options...
shinyribs Posted September 22, 2017 Share Posted September 22, 2017 Liters / 100km? WTF did I write? lol. Yeah, I think he's on metric readout, but should he also be seeing kilometers on the Speedometer readout then? Link to comment Share on other sites More sharing options...
rick Posted September 22, 2017 Share Posted September 22, 2017 I accidentally switched my speedo to read km/hour. Have no idea how I did it and man was I scratching my head for a bit on that ride when I looked down and it said 100 - wtf! - no way was I going that fast. lol. Yep, it's gotta be reading liters. But I pay absolutely no attention to that mpg gadget. It's only taking a guess based mostly on the throttle position sensor. As long as my car is moving, when I let off the gas pedal completely, that feature will read 99 mpg on the dash. If only my Subaru Outback could get that kinda mileage. What's more important is how much fuel it takes to fill at whatever mileage. But if the thing is only getting 100 miles with a 3 gallon fill, well, I believe in a fairly vigorous break-in, but that might be a tad too hard. BTW, 93 octane fuel is just a waste of money in this bike. The book says 87, mine will run OK on this, but I usually up it to 89. Link to comment Share on other sites More sharing options...
drewpy302 Posted September 22, 2017 Author Share Posted September 22, 2017 Thanks for the responses guys. It may be reading kilometers, for sure. That makes sense. And I'm not sure if it was a full 3.7 gallon fill-up. It was on the last blip on the E, and I put gas in the tank till it clicked and was about 2.6 gallons or so that I added to it.

johnakay Posted September 22, 2017 Share Posted September 22, 2017 the only way to check accurately your mpg is to fill up before your ride. when the times come to fill up write your mileage down and keep your receipt. theres 3.78 ltrs to a us gallon.so if you did 105 miles and used 5.6 ltrs 105 divide that by 5.6 =18 miles x 3.78 = 70 mpg etc Link to comment Share on other sites More sharing options...

Don't think anyone's gotten Yamaha's claimed 3.7galloans in. 3.3 is probably more realistic Link to comment Share on other sites More sharing options...

Global Moderator tavisb Posted September 23, 2017 Global Moderator Share Posted September 23, 2017 Still trying to figure out the gas thing myself. My first full tank got me a low fuel warning at 103 miles. Filled it back up at 107 and it only took 2.3 gallons. I'm going to have to fill up a fuel bottle and run it until it dies to see how much range it actually has. youtube.com/tavisbogue Link to comment Share on other sites More sharing options...
Premium Member norcal616 Posted September 23, 2017 Premium Member Share Posted September 23, 2017 when the last bar starts flashing it means your on Reserve... 2015 fz-07- Hordpower Edition...2015 fj-09- 120whp- Graves Exhaust w/Woolich Race Kit- tuned by 2WDW Link to comment Share on other sites More sharing options...
Global Moderator tavisb Posted September 23, 2017 Global Moderator Share Posted September 23, 2017 So is the reserve like 1.5 gallons? youtube.com/tavisbogue Link to comment Share on other sites More sharing options...

Maybe even more. 😁 Link to comment Share on other sites More sharing options...
shinyribs Posted September 24, 2017 Share Posted September 24, 2017 I thought each of the six fuel bars represented a half gallon each. So, using up all six fuel bars ( 3 gallons) puts you on "reserve", or the flashing fuel bar- meaning you were on your last .7 gallons of fuel. So is it a known fact that the tank doesn't actually hold 3.7 gallons? I really miss petcocks with a reserve function. Such a reassuring feeling...

dmoney Posted September 24, 2017 Share Posted September 24, 2017 You might be on a km/l setting which would give you about 8L/100km which translates to around 29mpg. Still high usage but that'll give you about 100 miles for the tank. Take a photo of your dash while on that setting so we can see whats going on. Failing that, when you take off just shift the left foot pedal up and that should put it in 2nd gear. Repeat to go up more gears 😜 Link to comment Share on other sites More sharing options...

I regularly see 120km with all 6 bars still there. Havent quite worked out which bar is how much. I just work it out based on avg l/km and go from there Link to comment Share on other sites More sharing options...
rick Posted September 24, 2017 Share Posted September 24, 2017 Fuel taps, lol. Gone the way kick starters on street bikes. I don't think I've ever put more than 2.8 gallons in with the light flashing and trip meter counting up - btw, I hate that feature. Because the tanks are relatively small and almost always have an odd shape, think you'll find that most motorcycle fuel gauges are not very linear. My Aprilia's is no better, but has a 5.5 gallon capacity. Think you'll also find there's some variation in each fuel level sender inside the tank. The float moves a variable resistor that the ECU converts to a level. So there's gonna be some mechanical variation from part to part. And because it's measuring resistance, maybe even variations in the fuel can have an effect. But think about it - if you could overfill the tank to the top of the filler neck, the gauge will read Full for more miles than it would if the fuel level was right where the float tops out - and that's not likely right at the top the tank anyway. So yeah, ya ride and ride with the thing saying 6 bars - sweet, it'll never run to of fuel - and then all of a sudden, it starts to drop quickly. So think of that flashing last bar as your old fuel tap in need of a reach to flip to reserve. That old R90/6 in my avatar had a fuel tap on both sides. i don't miss having to reach down mid turn or to finish a pass. Oh, I've also been carrying a small fuel bottle since new. Haven't needed it - yet. Link to comment Share on other sites More sharing options...
