Gas Mileage- Is your a Sipper or iz it Sooopazz, yo!!

[kamikaze]

i'm getting about 48mpg (4.9l/100km), but since the break in I've been riding it like i stole it

edit: on a side note, anyone with an iPhone/ipod touch looking for an easy way to track mileage, get AccuFuel. That's what I'm using, and it works great. takes about 30 seconds to input the mileage, amount and price of fuel when you're done filling.

[wayanlam]

definitely not a strong suite for my bike, last calculation i did (dont remember sactly how many km, lol) was around 220~240 KM when i filled up the tank with 16.4L of fuel, thats like 13.4 to 14.6 KM/L = 32 to 35 MPG....

how do ppl get over 60miles to the gallon! O.o must be them darn long straight roads with the 70mph speed limits over there in the civilized worlds!

[highpsiguy]

I think height and weight should be listed with fuel mileage results as well. I had an 07 that still got around 60 during its break in time.

Just sold an 09 Versys 650. I averaged 50 mpg with it.

I have just purchased a 02 Ninja 250. Have yet to ride as I am having 15t front sprocket, new tires and carbs cleaned out 1st.

My height is 6ft 4 Weight 245. I feel size/weight should be considered.

i am 5ft 7, and weigh 137 pounds... and i still get almost half your mpg

wonder if i'm running way too rich ...

[want1sobad]

52-53mpg, i always get 210-220 miles to a tank. 15t sprocket swap, stock can, shimmed needles, snorkel pulled. 99% of my riding is highway commute at 75mph - when accerlerating onto the highway i shift at 10k. 5' 10" 182 lbs.

[srsly]

Just filled up yesterday with 150.x on the odo and put in 3.5gal for 42.8mpg. No change from before I got the yoshi full installed. This was 90% in-town/commuting with not much slab time.

[ztrack157]

My mileage sucks. Not fun when it costs $100 a tank.

[capt_bugaloo]

I find that my 2008 250r consistently gets about 45 MPG in the city. Frankly it is a bit disappointing. I used to have a Honda XR200 (air-cooled 200cc single) that got over 90 MPG. Mind you, it didn't have anywhere near the same top speed or acceleration as my Ninja... :-|

Did you install an aftermarket Chevy Suburban gas tank on yours?!

[ztrack157]

nope

[wayanlam]

hes using jet fuel, NOS and a pinch of gold powder just for good measure and its BlingBling factor... or... Matt put a 35 gallon fuel-tank on his 2fiddy for a non stop cross country ride :P

rofl...

[highpsiguy]

Well I see too late that this post was for 2008 plus bikes...

My bike is an 02, but will post anyway.

Just got back from 700 mile round trip. My fuel mileage for first tank was 56mpg, second tank I tried hi test 54mpg. The third tank I was running interstate wide open in 6th gear and got 44mpg-yuck. The last tank when I got home and filled up was 48mpg. I probably averaged around 65 mph when not traveling interstate. My rpms averaged between 7 and 9k.

Again, this is with fresh tune up, new tires, new 15tooth sprocket. My weight 245lbs height 6ft 4.

I was hoping for 75mpg....didn't happen. Not sure what to do to make it get that. Bike is stock except for the above. My 09 Versys 650 gets this mileage almost exactly with tons more power. I am still happy with my little ninja though.

[Ytse Frobozz]

I'd say I get about 55. When I do longer rides, I'm definitely up around 60, but my 8ish mile each way commute eats into that a lot. For comparison, my Dodge Magnum doesn't even come close to being fully warmed up by the time I get to/from work, and thus I average about 14mpg on that commute.

[HorizonXP]

Man, I'm 200 lbs without gear or my backpack, so maybe 250lbs with it. I'm barely hitting 40 MPG. My bike is bone stock.

I need to sync the carbs and swap the air filter. Would that be a culprit?

[kkim]

what kind of riding is the majority of bike use comprised of?

[HorizonXP]

Mostly highway commuting lately. So anywhere from 100-140 km/h, but mostly averaging 120 km/h.

[kkim]

hmmm... I would think you would get great gas mileage with the bike in 6th and having the throttle at a constant, cruising speed.... you are in 6th, correct?

are you sure your choke is adjusted properly so when it is in the "off" position there is free play down by the carb slider bar thingy <highly technical term ?

[HorizonXP]

I'm in 6th unless I have to gear down to pass a semi.

I have not checked the choke free play. This could be a culprit, as I do find that when I use the choke and start it, the bike does rev to 4k rpm quite readily, and idles at 1500 with the choke off. Will look at it tonight.

this sounds normal, but check the choke anyway.

also, when you push the bike around in the garage, does it feel like the brakes might be dragging?

chain lubed and adjusted properly?

Brakes are not dragging. Bike feels fine when pushing it around, and the tire rotates freely when I have it on the rear stand when I'm lubing the chain, which is after every gas fillup. So the chain is properly lubed and adjusted, with the appropriate amount of slack. Had that done by a mechanic, who did it while I sat on the bike to ensure the rear shock was compressed to the point where the chain had max tension.

Things that make you go hmm....

Averaging 75 or more mph isn't going to get fantastic mileage. There's of course nothing wrong with checking to see if there is a culprit on the bike that is hurting mileage, but before you spend a lot of time and effort, try one more thing. Go at least 50 miles (*quickly does conversion*) 80 kilometers at a constant speed closer to 100 km/h. Start with a full tank, and calculate your mileage right after when you fill up. If the mileage gets closer to 50+ or even approaches 60 mpg, there's nothing wrong with your bike. At high speeds on the highway, the mileage just isn't going to be that great.

[kkim]

I assume you're doing accurate calculation of your mpg and not by the "I'm gettin' X miles per tank before fillup" method.

mileage since last oil change? I know I'm gonna start a holy war over this next comment, but you might try switching to a synthetic oil, if you haven't already. Not saying it will miraculously give you 60mpg, but every little bit helps.

next time you have the opportunity, remove the spark plugs and see how they look.

yeah, I missed that... the whole km/h vs mph thing. Still, 40 mpg sound a bit low, doesn't it?

Uhhh... I'm going by my trip meter, and the amount of gas I put in the tank based on my receipt. I didn't realize that wasn't accurate.

I just recently switched to synthetic Rotella T6, it didn't seem to help a whole lot. I have new plugs that I am planning to put in, but I did take a look at my old ones when I did my valves, and they had a little bit of blackness on the element, which as I understand, means I'm running rich. Sometimes, when I turn on the bike, or I'm at a stoplight, I do get a strong gasoline smell.

I will try Alex's method of measuring MPG this weekend when I have a bit more time.

That's the way to do it. It's accurate.

I'm similar weight, ok 25lbs less but i bring a big heavy chain, a big heavy camera and a big heavy laptop most places so it probably adds up to the difference.

I do similar commutes during the week. According to gps when the bike says 140km its doing 120km(75mph). Have run it up to 165km also (on a closed road of course )

I'd check tire pressure before I'd check anything.

I'm getting worst case 60mpg and best case up to 70mpg. Although I think UK Gallons and US Gallons are not the same? Which one are you measuring too?

From handy-dandy google: 1 Imperial gallon = 1.20095042 US gallons

So you're seeing 50 mpg to 58 mpg in US gallons.

[bob706]

I've tracked my mileage from the day I got the bike and I'm getting 56mpg(average for two years). My highest tank was 62mpg and lowest was around 50.

I prefer UK gallons then

[caferacer]

I get 50-52 mpg...I have a full yoshi pipe (without the quiet core), K & N filter,
dynojet kit, kleen air removed. I rev to redline most of the time up until about 60-65 mph unless getting on the interstate. I guess 50 is not bad but my last bike was a 955i triumph daytona and it got 42-44....go figure...

[srsly]

I ran out of gas a couple days ago with 186mi on the tank. Still have the yoshi, still jetted up. I'm 6'1 @ 160lbs. I think I'm running rich and/or leaking somewhere. My buddy brought me a gas can with maybe a cup or two in it and when I filled up the filler read 4.7g. I've had a heavy hand lately but there's no way I could go from mid 40s to under 40 without some kind of problem...

[slolane]

I'm 170lbs, on my 2008 (Pipe and jetted). I commute 2-4 days a week and do some weekend twisties/light touring depending on the mood and riding group. On the highway I stay right around 65mph and I'm 30% highway/70% city. Per tank I average 60-65mpg on the stock gearing. Chain is always lubed and tire pressure checked/corrected. I just purchased 15/42 so I will try that gearing and see how it rides and if the mpg's change.

[scotty]

I'm in the mid 40's now. When it was stock I was getting 55-60's mpg. Now with intake mod, jetting, and exhaust I am in the 40's. Im still pleased with it. Also, its colder where I am at now so that could play with what i'm getting. Maybe when it gets warmer it will go up to the low 50'.?.

[JMcDonald]

I've got 44-45 on every fillup since the first two, heh. Though almost all of my riding is either short commutes or long, quite spirited rides .

[CZroe]

Got 39MPG last time and I wasn't too bard on it either. Remember, I'm at 15:41 too.

[JMcDonald]

My mileage stayed exactly the same when I went from stock to 16/41, even. Also, even after I changed the jets and added the pod filter, it didn't change. I've been toying with tuning a bit more since I recently finished my exhaust system, and my fillup today was like 45.5mpg.

[kenji_808]

When i first got my ninja250 i was getting a constant 54-55mpg
after installing a yoshi full carbon slip-on with silencer insert my mileage went up to 58-59mpg

Besides the slipon bike is all stock engine wise...
with full gear on i weigh about 150-155lbs

My riding style is all high rev shifting around 8-9k consistently, what can i say didnt geta bike to go slow use my car for that lol. I'd say i ride about 50/50 between highway and city.

IMHO i love my ninja 250 i dont plan on selling it ever, even after i upgrade to a 600

[brezim123]

After reading some of these posts I am loving my bany more and more. About 60% of my riding is in town mostly flat land. Although it may take you 20 minutes to go 10-12 miles due to lights and amount of traffic. My driving sttle driving style depends on amount of traffic but usually in a hurry, lol. The baby weighs 347lbs and I add about 130-135 in full gear so the 2 of us do not make 500lbs. I get about 70 mpg. If I do a trip to Key West (180 miles) I get about 75mpg but that's running down #1 and thru all the Keys. My bike is '05 and all stock.

I have been getting in the upper 40's. Most of my riding is freeway and highway-65-75mph. I have the Roaring Toyz hanlebar risers, so that makes my big fat body sit upright and catch more wind. I'm going to plan a trip with mostly 50-55mph riding and see how much the mileage increases. Also I ordered the 15 tooth sprocket-hope that can get me into 50mpg.

[wyckedflesh]

Since I am now sharing mine with my son:

2009 250R Two Brothers Slip-On, DynoJet jetting kit, 3rd Ring from Bottom, 112.5 Jets and Uni individual Pods, drilled slides, stock sprockets 140 Sport Demon Rear tire.

Me: 5'7" 220lbs in gear if I haven't eaten 50mpg 65-80mph Freeway 55+/-2mpg City, mostly 5th gear riding.

Son: 5'2" 135lbs in gear sopping wet with fishing weights in his pockets so far mostly City with very brief stints on the freeway to not get a good idea...68mpg

Ordered Vortex Sprockets F: #3202 15T R: #435 42T

Will be interesting to see what effect it has.
