gas mileage

I have an 82 750 maxim. I bought it last summer and have put 4k on it. It only had 14k original miles on it when I got it. I was wondering what the approximate mileage per gallon I should be gettting. I am getting 37mpg att. Is that low? If so, any ideas what I can check? Thanks for the help.

 

Do you ride it like an Accountant going to work in the morning ...

Or, ...

A Fighter Pilot just launched from a Carrier's Flight Deck?

 

I rarely do better than 35 with my 650 Seca. Doubt there's much difference between the 750 Maxim and the 650 Seca. I suspect you're in the ball park.

High 30's when having fun, low 40's riding at legal speeds.

I once got 52 mpg on my 650, but knew it was a long way from the next gas stop, so I went through that tank of fuel pooping along at 45 mph in 5th gear.

Your mileage will vary with how much you twist the right grip.

 

I ride like a bit of both, Open road, fighter pilot, town...accountant. How much difference will it make

 

i guess then the 37 is about common. I should just be thankful

 

I don't know what mileage I get - but I KNOW IT ISN'T GOOD!!!!

HAHAHAHAHAHA!!

Sorry folks - the moment took me...

 

flashsnapshot, think of it this way, no matter how bad the mileage is on your XJ, unless there is something REALLY wrong with it, you'll never get as bad of mileage as I get in my Dodge Ram Quadcab (12mpg, 14 on a good day).

 

Mileage on bikes has always perplexed me a little. Of my bikes. The Goldwing with its 700+ lbs and 1100ccs gets by far the best mileage. It regularly does 45 and I've had tanks go over 50.

I think the key is aero. At least at speed. Around town weight is probably more important.

My Harley, not surprisingly, is the worst. I rarely do better than 30. I tend to beat it pretty hard though, always hoping to find some Seca like performance in there. Amazing what a little technology will do for you.

 

I got 37 to 38 out of my 82 750 last year. I put a small windscreen on it an it picked up another 2. After adjusting the valves and setting the float levels. I dont know yet. I know I have been 47 miles and it still says 3/4 tank. Riding style would be the biggest factor in my book. Generally at 140 miles I am looking for a gas station, wheather I need it or not.

 

Gas Mileage is a funny thing. My Maxim 1100 used to get me 190 miles a tank when it had the airbox and stock exhaust. That was 40mpg. But a rejetting and removal of air box for seperate K&N's and Kerker 4 into 1 and it is really more dependant on how I drive, at best now it might make 38 on highway.
But I'm averaging around 34, but my bike does a lot of running while sitting as I don't drive it all the time, but start and run it regularly. I advanced the pickup plate to see if this trick would improve mileage as it hugely did on my FJ1200. After I advanced the pickup on my FJ, that 1200 would actually get me 54mpg if I rode with elbows on knee's which was a perfect posture for my height on that bike. When not, it would do 51 around town. Before I advanced it, it got 41 so it picked up 10mpg on that bike, But the Maxim didn't improve from doing this change. It's mileage has stayed the same.

My Vmax gets 40mpg with Kerker pipe, I've kept the airbox and shimmed the (what they call the "Y") which is the top airbox feeder, and haven't changed any jetting just tuned it. I always find it interesting smaller bike engines don't seem to do any better on fuel mileage. I know the guys that went to full stage kits on their Vmax's the mpg really drops off.

I kind of think its common if you end up seeking changes for performance, you have to expect loosing some fuel economy which is something everyone should think of seriously if it's worth it to them, especially with gas prices now days.

 

I'm getting between 40 and 43 on my '82 650 Maxim. All it has is the K&N filter and I ride like a fighter pilot most of the time.

I appreciate all the responses. It is great to have a site like this where I can go and even ask stupiid questions. Ha! Now to fix the warning light problem! Thanks again-

 

I have a trip computer on my EFI XJ750.
It reads in Km / L.
110Km/h 19 - 24 Km/L depending on conditions
100Km/h cruse 22 - 24 Km/L
50Km/h round town 5th gear 26 -30 Km/L
70-80Km/h 27Km/l
Average trip 20 Km/l

 

sorry but I am metric illiterate???

 

Hey:

I don't think I will ever get the metric system but htanks for the info... BTW rickomatic i am in the emerald isle topsail beach area. Great place to ride year round. "Flash"

 

I've been filling my XJ650 Maxim from jerry cans, so I don't know how many liters I'm using. I fill it till it touches the bottom of the filler pipe.

Tank before last I got 177km before I had to switch to reserve. Today I got 170km, but that included a 10km climb on a mountainside outside of LittleFort BC where I was opening the throttle quite a bit to burn out any carbon in the cylinders. Other than that climb it was driving the speed limit, not aggressive.

How does that compare to the distance other 650 owners get from a tank of fuel?

 

On my turbo I am getting around 46 mpg. If I can keep it off of the boost and put it into conserve mode I have gotten about 51 mpg. However if I am on boost it has dropped into the low 30's
When I had my stock 550 when it was in cruise mode it was 54 mpg and my 550 race bike, in race mode was............... expensive!!!

My XJ1100 gets 38-40 , bone stock
XS1100 gets 30-35 , K&N filter and 4 into 1 exhaust with re-jetted carbs
The wost of the bunch is my F350 truck, gets 9mpg unloaded and as bad as 4 fully loaded with the boat in tow.

 

4 mpg? thats gas station to gas station! I bet thats a lot of fun with 3 dollar plus gas prices.

 

My last tank on my '82 650 Maxim got 45 MPG. The highest I've gotten was 51 and the lowest so far has been 41.

My 1979 DT175 used to get over 85 MPG but you couldn't really take it out on the highway.

My 750 Virago only got about 35-40 MPG and it had much less power than a either a 550 or 650 Maxim.

 

Well I got 45 MPG out of my last tank, with a passenger for the last 50km.

I was definitely driving gently, so this is a "best case" scenario, but I'm happy anyway...

 

just double it and add 30

 

40-45 MPG with my XJ750 Maxim MK

 

I think that applies to temperature only Time. IE 25Celcius = 80Farenheit (ish)!

 

Cheer up! OPEC loves you!

 

I get a standing 43 mpg unless I am acting like jet pilot.

 

Something is missing from this thread.
Who all has any type of fairing on their bikes?

My 82 750 YICS Maxim got 53 mpg on it's last tankful before i put on the Slipstreamer Spirit 02 windshield. (Fairly big shield)

Now i'm getting 45 to 47 mpg. I ride her about average. Sometimes putting along at the speed limit and sometimes using the fun handle.
If i hypermile, i can still push 50 mpg.

I suppose that's not bad for a 26 year old gal.

IMHO, this conversation is limited in value, if the fairing/no fairing question isn't answered.

I've never used the windshield for mine but I think i will for trips or colder weather, the problem with my 650 max isn't the milage it's the range I get from the sad little 13 liter (3.25ish gallon) tank not bad in the city but up north when it's 200+ km between stations??? the math just doesn't add up!

I thought I was accelerating pretty fast, cruising around about average of 55, but I was still getting an MPG of 50-52 on 100+ mile trips. No windscreen, and above 45 I lean down a bit.

I did have 1oz of acetone per tank of gas (5gal).

 

I have an 82 xj750RJ without fairing and I get 45 MPG on average or above, and I ride both hard and mild. I don't think I drive too mellow though, most of the time I'm driving sorta hard and still get 45+MPG.

 

Lucky. I'm currently getting 36-38 MPG on my 700. Wonder if thats normal for a 700 my age? I'm also 120LBS so You think i'd get more jsut for that! I ride pretty mild. Occasionally i'll go up to 6.5 RPMS but not daily. I try to stay below 5k RPMS.
Wonder if my new jets will help

 

I have a seca 900 and get 48 to 50 mpg no matter what riding conditions or maybe I just ride the same all the time. My Nighthawk 650 was 55 - 60 mpg. I can't imagine the mid 30's.

 

my last tank got 45mpg.

 

When I first got Arachne, the PO had her chugging out 32mpg...after a carb clean and other much needed maintenance (valve job coming up this season while i have the engine out) she ended the season doing 47. Ill be happy with 40 with what Im doing to her weight wise. Hard cases a trunk and fenders....

 

SLKid - I'm averaging right around 36 - 38 on my 700. This seems a bit low to me. I do tend to ride it more like a fighter pilot, but I rarely rev her over 7k unless I really need to.

I'm going to play with my colortune, as I believe I am losing a lot of gas when doing city driving and sitting at lights. My mixture may be a tad too rich.

 

.62K/3.785L = M/g (edited)

So 20K/L would work out to
20 * .62 *3.785 = appox 46.9 mpg

 

Seca 900 - 49 MPG on 4 tank back to back test (sport fairing)
Seca 750 - 32 MPG when I got her, just did 46 MPG last week (s/t fairing)
V-Star 1100 - 50 MPG unless I'm really hammering it (small shield)
Honda Silver Wing 500 - 45 MPG (full dress)
Elite 250 scooter - 85 MPG (no shield) And I might weigh 300 LBs.

 

I consistently average around 45 mpg, with full vetter IV fairing and lowers, hard saddle bags and trunk..... 1983 XJ650 Maxim

I get 47mpg on a bone stock 1983 XJ750 Maxim. It even sprays a little gas out of the petcock so I would probably get a mile per gallon or two more if I fixed the minor leak.

I typically shift up conservatively, at 15, 25, 35, and 45, unless I'm aiming for quick acceleration.

I ride mine pretty average, mostly conservatively, occasionally I'll get on the throttle. Get about 45-50 mpg on average.

 

hehehehe
I'm usually comin outta second at 45, don't use 4th and 5th much at all.

 

Most of my riding is in an urban area so I typically have lots of cars around preventing that type of acceleration. There have been a few occasions where I accelerated hard, revving both 2nd and 3rd up to about 9500 rpm or so, with the throttle wide open. But often, I am rolling down a 25 mph road in 4th gear ... and about 2000 rpm ...

 

SLK,

I get about the same on my X but All of my driving this year has been in town stop and go, stop, creeep, stop, go no runs longers than 1.5 miles to even relax a bit. I usually hit the low fuel light about 95-100 miles. with this in town crap I hit it about 70miles and usually put in 2.2Gal of fuel per stop give or take .10 of a gallon.

 

I get 27 to 30 weather I'm drafting semi's @55 or by myself@70.

My valves are a little tight. Does anyone think that will hurt milage?

 

first ride this season after cleaning carbs and going up one tooth on the rear sprocket. first tank was 165 miles 2.7 gal. for a nice 61 mpg. hopefully this wasn't just a fluke, lol.

 

Sounds about right; I got 56mpg with my '83 on its shakedown run and we was ROMPIN' at times. 16T front/45T rear (stock for the Seca.)

I regularly get around 52mpg with my '81 commuting, in more mixed traffic.

 

cool, that included idle time for the carb sync and i rode kinda hard for the last half tank. wasn't sure what i'd get cuz last year i got about 55 as an avg. but up to 58. this year i added windshield and saddlebags and went up to a 46T from a 45T and left the front sprocket stock. but hey, i'll take 61 or so. nice to have fun and it's easy on the wallet.
