How far do you let the fuel go down in the tank before you fill? I let it get down to the hump straight under the filler cap...from that point, it takes three gals. and mileage wise I'm right about 150-ish.

You know ...I never reallynoticed. When Ibought her, I ran her until I had to go on reserve to see when I should start looking for gas. She started cutting out at around 165 miles on the trip meter. From then on, I've just tried to fill the tank between 150-160 miles.

My Clymer service manual gives the capacity at 4.23 gal. with the reserve being 0.8 gal of that. I guess I do only put a little over 3 gal. in it at the pumps.

Might California models have smaller tanks for some reason?

 

No,our bikes allshare the same size gas tank, 4.2 gallons. Some of you just fill it a little sooner than is needed. There is nothing wrong with that. Pushing a bike with no fuel is not much fun.

I can get nearly 200 miles from a tank, but I usually fill up around 165 miles, that is two and a half days of commuting for me. On the safe side I figureI get 40 mpg, thoughI know I actually get 52.

 

Where are you guys getting these 3 gallon tanks????? Are they plastic race units or something? I've looked very hard and I can't find anything on a 3 gallon tank for the F2 OR F3. What gives???

 

There isn't a three gallon tank. As FNQuick said, at the top of the hump where it looks like the fuel has been used from the main part of the tank it will take 3 gallons. On my bike I can easily go 3 inches or so below that point before reserve. IIRC, i put 3.7 gallons in it last year without hitting reserve and 3.9 gallons about 4 miles after hitting reserve once.

Anyway, I normally fill up at 145 miles and my mpg averages between 40-45 depending on how new the oil is.

 

Last season when my bike was running perfect i got between 52-60 after i tuned the carbs because they were way out of whack... Its not running to well this season with a person on it for a full tank i get 43(all city speeds)

 

150miles before i hit reserve and that is good for about another 15-20 (don't ask how i know that) but avg 45mpg 91 octane or better, k&n filter, and a vance and hines slipon, with saddle bags, and if i am lucky that day, my girlfriend[sm=happybounce.gif]

 

Ok guys, here is a scan of my Manual, the tank is 4.23 gallons and the reserve is .79 gallons

 

Thanks Bud!

Krokus, that is about what I figured for the fuel tank. I can get over 3.5 gallons in mine without hitting reserve, but I always get it to the top of the fill area, almost to the point it overflows. I just feel bad about using a cc for a $12 gas purchase and want to get the most miles before I fill up again.
