I'm lucky if my Ultra averages 40 MPG. I definitely don't baby it though.

 

When I first got my bike I would start thinking about getting fuel at 200 miles on full tank, that was stock. changed a/c went to duels with pcIII now I better be looking for fuel at 180 miles. And it has been tuned buy a good tunner here in Phoinex. But that still has everything to do with the way you ride. Under 60-65 does better but mostly 65-75. Some times makes me wish I had a 6 spd trans.

 

i would have to agree with this statement. have no hard evidence but dang it sure sounds good.
i always wondered about that ethanol

 

40 mpg hwy average and 32 in town ( cuz Ima throttle jockey).

 

There's a BUNCH of things that can effect fuel mileage like:
Are your tires properly inflated?

Are you using the clunky OEM tires that came on your bike or a more free rolling tread pattern like ME880's or E3 Dunlops?

Is your drive belt or primary chain too tight causing more rolling resistance?

What weight oil and what type are you using in your primary and transmission in particular? Red Line heavy IS 250 weight! It WILL quieten the tranny, but has MUCH more drag than say a 75W85 synthetic and anything heavier than 10W40 isn't needed in the primary. If you want to REALLY lessen the primary chain's drag, use ATF.

Are your brakes dragging? Don't laugh. It's more common than many think.

Are the forward facing pieces of body work clean and waxed or are they dirty and do you have a bunch of extras hanging where they will catch wind? More surface area=more drag and clean surfaces let air slide MUCH better than dirty.

This list can go on and on, but you can see there's no one simple answer.

 

All good reading moe.

Hadn't though of it before but now that corn was mentioned, I have to agree. Every station I've been to here in FL is selling "up to 10%" of that instead of real premium gasoline.

 

Well, I must say on a trip from NF, NY to York, I avg around 42 solo. I was going 75 on the 390 in 6th. My afr was 14.2 on a tc96 and HQ 575 cams and 2:1 pipe. No headwork or 103 jugs at the time. From US15 when in becomes more rural roads I suffered a little. Interstate travel I can get decent. I filled up at 180 miles, to make sure I did not have any problems. I still had between .8-1.2 gallons left depending where I was in. I think anywhere high 30s to low 40s is obtainable.

 

My old man told me that the two things guys lie the most about are, How many women they get and their gas mileage!

 

240 - you ain't a Silverback 'till you crest 250. I'm 6'3" 280 and git 42-44 regardless of how I ride.
