Gas mileage poll

[theLeopard]

Now with UNI's, Suppertrap slip-ons and proper jetting

When the time is right, can I ask you for a tutorial on increasing my performance with said upgrades?
I'm not ready now, bike runs good and I'm busy with school, but afterwards I would like to upgrade.

The mileage on my '92 FJ1314 varies between 35 and 43 mpg (US). There seems to be a correlation between the twist of the right wrist and the fuel gauge. Not much difference between this FJ and the '86 FJ1200 that I had from '94 to '05. The best range (calculated) that I ever got to a tank was just over 250 miles (400 km).

Mileage on my '84 with RPM's 1350cc engine, UniPods, 42.5 pilots, 122.5 mains, needles up 1 notch, 5 degree ignition advance with 18/40 gearing is ~33 on the low side to 36mpg on the freeway.

With 40 pilots and 117.5 mains I got as high as 41mpg, but the engine was not happy......I like happy.

Mileage on my '92 with DynoJet stage 3, UniPods and Kerker 4 into 1, 5 degree ignition advance, 18/40 gearing is ~42 mpg all day long.

My '88 with stock everything except slip ons and jetting adjustment ran in the low 40s ( US), rising to high 40s as the engine got older and looser just before it started eating oil at the 120 thou mile mark then steadily got worse till I replaced it.

The 92 with stock everything was around the low 40s the whole time I had it.

The engine was such a torque monster stock or near stock I wondered why anyone would want to mess with it. Then I rode Arnies. Yeah it was worth it.

I get about 40 under normal, town, and aggressive riding conditions.  I've seen as much as 59 a couple of times.  This is at 60mph ~3500rpm  for over 100 miles or so.  I also only weigh 135lbs, I'm sure that has something to do with it.  I've got a Dyna 2000 ignition and Supertrapp exhaust.

My SV1000 gets around ... not enough.

This may have something to d with my right wrist 

Right Henry? Dean?

Don't think its you.  I have a Cagiva Navigator with the TL1000 engine and it doesn't match the FJ for mileage.
As a matter of fact, neither does my Aprilia Shiver and that's only a 750cc V-twin.  FJ's hard to beat.

Mileage on my '84 with RPM's 1350cc engine, UniPods, 42.5 pilots, 122.5 mains, needles up 1 notch, 5 degree ignition advance with 18/40 gearing is ~33 on the low side to 36mpg on the freeway.

Same engine, 39mm FCRs, 18/41 and I get ~31mpg in daily use as a commuter ranging to ~36mpg at ~6000ft elevation riding in the Sierras last week.  This was also my first >4,000ft elevation run since the dyno tune of the FCRs and the bike ran great up to ~7,500ft on the passes.

Touching on another point that has been discussed here...  my FCRs were tuned at sea level effectively and ~75F.  I've run them in ~45F at sea level to >100F at 7,500ft with mild performance impacts (richer cold, leaner hot and high altitude, but no knocking or anything destructive).  I don't believe these carbs on an FJ are nearly as finicky as one might think...

That one was more of an inside joke.. I ran out of gas on the cherohala two rallies in a row... come to think of it one of those was on my YZF600....

With the temp threshold reprogramed on the ECU in Randy's fuel injected system, I wonder what kind of mileage he is getting?

Hmmm... I'm almost two of you. 
Guess I should be happy with 35 mpg.

My FJ is like a hybrid compared to the Kawasaki 500 triple 2stroke I owned when younger. That thing was petrol cooled I think, and would only get 20mpg. A lot of fun though.

My H2 used to get about 23.     

+1 on the fun factor, though...  except for the shift pattern.

...and until you wanted to go around a corner....that flexi-flyer frame was frightening

I always felt that was overhyped.

The shocks were what was really scary...
