Hi guys,I was thinking my new old 1992 fj was running rich and using more fuel than normal.I rode a mixed ride today city, hiway  and  achieved 170 km on a half tank of gas(tank was full).
Does this seem like normal or bad fuel economy?If I run at 160 kph on the hiway for a while you can watch the the fuel gage  drop 1 tick every 5 mins it seems.
thanks
1992 fj1200abs  75,000 kms  bikes runs fantastic.

Sounds about right to me. I will get 300 -350 Kms a tank depending on how hard I push it.

Cheers

With my bone stock 86' on original carbs I was getting an average of 49.3 MPG, tracked from mid 2011 through 2012 (yea, I track every fill-up). Then I re-jetted and put UNI pods and Suppertrap slip-ons on. Now my MPG is averaging 45.3. I hope that helps you get a reference...

I would do back flips if my '84 got even 40mpg...that 1350 is thirsty. 36-38mpg is the norm for me.
#45 pilots and 127.5 mains will do that to you....along with drawing in 22% more air and fuel.

What can you expect from an Over Achiever and polishing freak. Imagine how much more you would lose if you failed to keep it all clean...????

I've got you all beat for shitty gas mileage.. :lol:

It's a stretch to get 160 miles out of a tank on my bike...  My folks live 165 miles from me..door to door.. Leave with a full tank and have to stop before I get there and fill up again.. 5+ gallons each time..  Plugs look good..

Stock engine, uni-filters, upped jetting, 4-1 exhaust.. and some really worn out slide needles and E-Tubes..

I know the slide needles and e-tubes are the problem.  Carbs have been totally cleaned and new guts installed.  Now.. if I hadn't fubard one of my floats while putting things back together, I'd be riding..  :dash2:

34-41, probably average about 37. Haven't touched the carbs yet. Stock everything 86. Lately my averages have been higher for some reason, getting more 40's and 38's than usual.

I stop every 100-125 miles to fill up pre-emptively, however, as my petcock has monkey's syndrome. :(

Not everyone understands what a completely rational process this maintenance of a motorcycle is. They think it's some kind of a knack or some kind of affinity for machines in operation. They are right, but the knack is almost purely a process of reason.

Mark(monkey) should not be aloud to post on the gas milage topics. Never heard of anyone squeezing milage out like he does. Not that I don't believe him, I do. Ive seen it but don't understand it. I get about 38 mph. Like other normal FJ's!

So my question is of riding style, does he keep his bike spooled up or does he lug it around ?  :unknown:

I get about 300km before the gauge shows the big E, riding sedately. A lot less with the woman on board, even  though you don't feel it power wise.
