Gas Mileage

I have a 1986 Interceptor 750F. Can anyone tell me a range of MPG (miles per
gallon) I should be getting? Right now I'm getting less than 30 MPG. Is that
normal for the year and engine size?
Thanks!

I used to own that same bike. I would consistently get 230 miles to the
tank. After I installed a full Hindle system and rejetted the carbs, that
value dropped to 180 miles to the tank...

Hi John,

My 86 700 gets around 40mpg most of the time.

30 seems quite low.

Is the bike stock, or have any of the following been changed:
- exhaust system
- carb jetting
- gearing (sprockets)
- wheels
- tire sizes

When was the last time it was tuned up?

Dan

I was getting mid to high 40mpg range with my '99. PCII tuned on the dyno,
TBR full system, gearing change, K&N filter. I'm getting like results with
my mostly stock '04. By mostly stock I mean no PC, or gearing change. It
has Staintunes, &a K&N. I've gotten as many as 260 mi. per tank with the
'99 leaving about a 10th of a gallon, and 230 mi per tank with over half a
gallon left over in the '04.

I have a 1998 VFR 800FI which gets about 44-45 MPG with a PC II. Without
the
PC II installed, I was told I would get about 49MPG....is this true, or
is
someone blowing smoke?
Normally I fill up my tank when I have used about 4.6 gallons and I
typically
get around 208 miles with about .8 gallons remaining in the tank. I use
Synthetic Mobile One oil, 20W40
Is there anyone out there that has some different data? What kind of milage
should I be getting with a 98 VFR 800FI

I seem to average about 37mpg on my 2000 VFR w/ PCII and Staintune. I'm
still using the default PCII maps, so in theory my MPG might change if I
used Staintune-specific maps or customized the map a bit.

The guy I bought my bike from claimed he consistently got 45-50 mpg. That
was when the bike was totally stock. Also, he did a lot of long-distance
commuting, which probably helped.

I have '00 VFR 800 with a power Commander.
I was looking for idle and mid range drivability.
When I first installed my Power Commander the fuel economy dropped
considerably. No improvement in the idle, but the mid range was much
improved.

I set up a wide band ego sensor and took samples while I was riding. What I
found was that the stock fuel map was very lean (so lean at idle the bike
would stall just sitting there). The PC maps did nothing at idle,
indiscriminately added a lot of fuel through the mid range and where tuned
for power in the upper ranges. This improved the driveability of the bike,
but is cost fuel economy. With much tweaking of the fuel maps I was able to
get the best of both, nice idle, tractable midrange and return to decent
fuel economy.

Originally I would get 325 to 350 kM to a tank. With the base PC maps it
dropped to ~ 275 km per tank.
Now I get 350 ~ 375 kM per tank, filling with 17 - 18 Litres.
This works out to 55 ~ 60 MPG Imperial, 46 ~ 50 MPG US.

Perhaps not blowing smoke, but maybe smoldering a bit 8-)

My '98 is stock and gets 50 mpg only under very specific conditions:
Minumum speed in top gear (around 50 mph), no wind, no hills. Typical
is around 40 mpg in normal freeway traffic/speeds, milege drops to mid
30s at high speeds or against strong headwinds at freeway speeds.

In slow twisties (30 mph, lots of hills) 40 mpg was typical.

Seems to me your numbers are really pretty good.

I was able to squeeze over 50 MPG out of my '97 a few nights ago, and
that included more than thirteen miles of traffic jams and a typical
cruising speed of 70 in clear conditions.

Throttle control, short-shifting, etc. all help!

Stock 5th gen = 45 mpg average!

I have a 5th gen (99) that is stock and I normally get right at 200 miles before the low fuel light comes on. Normal fill up is about 4.5 gallons which yields about 44 mpg. On an 8100 mile trip out west last year in June, of which 4000 of the miles were done two up (me= 210 lbs, daughter=110 plus 60 lbs of luggage), in the 25 days of riding I averaged right at 45 mpg in spite of numerous long runs at 80 plus mph. Lowest mpg – just above 40. Highest – almost 50. Elevation – sea level in San Diego to 13,200 feet in CO. Temp range – 104 in AZ to 34 at various higher elevations. Ethanol blend, which I avoid whenever possible, and winter blend gas reduces my mpg by 2-3. The lowest mpg I have ever gotten was riding in a VERY spirited fashion on tight twisties where I kept the revs up for most of a tank and, as I recall, I got 37 on that tank. In normal riding, my mpg is very close to 45 mpg. I ride with another 5th gen rider whose bike is stock and his mpg is very
similar.

Got out with a few buddies today to the tune of 275 mi. Filled up where we
met and filled up again at 186.9 mi. That figures out to be over 47.5 mpg.
Mix of twistys and gentle rolling roads. All done at a spirited pace with
the air temps in the high 80's to low 90's. Too hot and humid today to go
balls out but I get the same mileage balls out. The other 6th gen. on the
trip (not a lister) got similar mileage.

I got 44mpg the other day commuting in DC traffic mixed with a dash to Summit Point on Snickersville Turnpike...I usually get around 38mpg...that is until I cleaned all the dog food oiut of my air-box that a little furry brown creature had stashed in there...

Matt
 
So far I've been getting about 4mpg more than I was getting...
 
Denny is a freak by the way...but not for wearing perforated leathers and getting 44mpg+ on average...but I won't embarass him here ...I'd rather do it in person.

Denny,

I would think the balls out thing would be cooler, but adversely affect your
wind resistance. I'd be careful with that technique though it could end you
up on an offender's list.



Matt,

Does that freak thing have anything to do with needing to wear the
perforated leathers down to 40F? He doesn't have a penchant for burritos at
lunch does he? That with perforated leathers may account for some of the
better fuel economy.



On a more serious note (BTW, it was great seeing you guys at COTU :-)) I
used to get 42+ mpg all the time with my first '94 VFR. I get less than
that with my current one (about 36-38) but it is currently running rich
enough to smell. I expect it to get better when I get in to work on the
carbs.



And for you FI snobs, my '98 got worse economy and only showed a benefit
over carbs when over 5000' in the mountains. The automatic "rejetting" is a
nice feature, but the bikes still lack the sophistication of the car systems
and are only approximating the features built into carburetors for years.
