Gas mileage poll

[Paul1965]

I'm just curious what kind of mileage other FJ riders are getting. I was getting 45+ until I added my mods (Uni Pods, Yoshi 4 into 1 and carbs) and now my mileage has dropped off more than I would have thought.

[aviationfred]

My gas mileage is usually in the 43-45 mpg range. I have the 18/38 tooth sprocket set up. Last year on my trip to Gunnison, CO. I had 2 legs that came in with 53 mpg. Granted I was traveling on the highway and a dozen or so small towns with speeds down to 35mph for short distances.

The Central FJ Rally is less than 2 weeks away. The mileage from my house to The Hub, is 361.48 miles. I am going to attempt to go 300 miles on a tank of fuel.

My math says 53 mpg can make it. 300 miles, 5.8 gallons = 51.72 mpg required.

I will keep everyone posted on whether I am successful or how many miles I did make, before I failed.

I feel your pain... still trying to work my way through it.   

Used to get 43-44, dropped about 10 after the airboxectomy, but I've got it back to 38 now.

Mine had initially dropped to 30 mpg. I played around with the jetting, swapping in 112.5 mains and 37.5 pilots and dropping the needles one notch. Today I took a trip to Sublette IL where I managed to get 38 mpg. I guess that isn't too bad since it was quite a bit of stop and go on the back roads and also included blast down I39 at 75 mph into the wind, but I want to do better than that. Maybe I need to look into changing gears next, especially since I keep trying to shift into 6th

Hmmmm, miles, gallons...?
Ok, I know a mile is 1.6km (1600 meters) but how much is a gallon?
School was a long time ago, but I think a US gallon is 3.78 litres, and a UK gallon is something like 4.54.
So, if I recall correctly the 1200 had a 22 litre tank (I think 2l is the reserve) which makes total capacity of about 5.8 US and 4.8 UK gallons.

Now if we assume my conversions are correct then the rest is easy.
First, I cant recall what the bikes sprocket sizes or jetting were/was but I am almost certain all of my FJs were factory.

On a normal trip I would comfortably get between 350 and 400km (220-250 miles) on a tank (generally consuming about 19 litres).
However when the pace went up (a lot) I recall figures of 18L for around 200km.
Therefore; at around 19 litres of use my mileage would be around 220-250 miles from 5US (4.2UK) Gallons or 44-50mpg US (48-55mpg UK). 
The worst (or perhaps best) I saw was about 33mpg US (28mpg UK). :-)

42mpg with UNI filter in the stock air box and Yosh slip-ons and 18/38 gearing.

Fred, I hope you're bringing a can with a gallon of gas, just in case.  Rumor has it a 550lb FJ is a pretty tough to push for more than a mile or 2

Fred,

you must of landed on your head when you got rear ended
bring a gas can with you or you will wear out the soles of your boots from pushing the heavy beast.

Fred had this plan before the accident. Yes he planning on bringing along a fuel can or two.

I think he shuts off the bike and coasts down hills. Hooks a rubber bungee to trucks for the up hills. Lets not talk about his low drag plan.

When my 86' was bone stock I could get 50MPG. Now with UNI's, Suppertrap slip-ons and proper jetting I get 42 to 46, 38 ish if I am following an aggressive rider.

I enjoyed the ride time we had at the rally, anytime Fred....

[theLeopard]

costs me about 10cents/mile.

[fj johnnie]

 18 front 41 rear. Best mileage to date is 49.9 mpg. I was following a guy on a cruiser and almost fell asleep. I hope my mileage never is that good again. Average is around 40-43. I will not take any slabs unless it is impossible not to.

[Bminder]

I do 95% town riding, under 45 mph or so. I think I'm getting around 35-36.
WAAAYYY better than the 11 my Dodge Ram 5.9 gas gets!!
And more fun too.
