My fuel level sensor is broke on my 900 and I have to keep track of my mileage before a fill up.
Did a search but didn't find much.
About how many miles can I go before having to fill up again?
Thanks

... depends on how many mods you have... I have a 750 and stock, I was getting about 190 - 200 miles on the odometer before the fuel light came on. AFTER I installed a K&N air filter and Sil Motorsport exhaust cannisters, I've been getting about 180 mi. before the light turns on.

Suggestion: travel about 130 miles before refueling... I'd say people tend to average b/t 130 - 160 miles depending on riding style, etc.

If you tend to burn rubber off the stop lights, gun the engine a lot and take off like a bat out of hell at stop signs, stop lights, and perform hooligan maneuvers, I'd fill up at 120 miles.

Interesting... I have a 750 and the light starts to come on at around 110 miles.

Re: How miles on a tank of gas

For my 97 M900 with jet kit (e.g., worse mileage than stock), it was always safe to ride at least 120 miles before filling. I once went 170, but was in danger of running out of fuel.

All you need to do is keep track of how much fuel you put in when you fill it back up. If it's less than 3.5 gallons, you could have gone further. Keep track for 1000 miles or so and you'll have a pretty good idea.

Re: How miles on a tank of gas

After all of my mods, the gas mileage went UP!! The light used to come on at 150, and now it doesn't come on until about 170. BTW, keihin's, big bore, poerted and polished heads w/ larger valves and a 2-1 pipe, and +4 on the rear sprocket.

Re: How miles on a tank of gas

95 M900 with unknown jet kit, open airbox, aftermarket cans. Mine comes on usually at about 110 miles. Always on by 125 miles. I always fill up at that point and it takes about 3 -3 1/2 gallons. When I actually calculated it closely and did the mileage, it came out to about 33 - 35 mpg most of the time.

(On the track it dropped to 25 mpg)

Re: How miles on a tank of gas

I've gone as high as 155 miles, but I was pushing it the last two miles to the gas station - uphill. That's when I found out that my fuel light was broken. :(

Lowest I got strictly canyon carving was 100 miles before the fuel light. But that was 100 miles of purely reckless behavior. Average is about 130 before the light.

It's an '02 S4.

Re: How miles on a tank of gas

M620D today went to 121 'til the light. Ended up at 40mpg.

Anyone ever go dump the airbox for little filters then have the tank enlarged to fill the hole?

Re: How miles on a tank of gas

Interesting idea. Would you enlarge the tank or build a secondary tank? I don't think much could be won, maybe half a gallon or so, but even half a gallon would be good for another fifteen or so miles...

However, the way the two smaller filters would be positioned would really limit what you could do to your tank to enlarge it. Unless you build an air-duct to the rear intake and position the filter in the front, next to the one for the front intake.

Probably not worth the aggravation, and my Monster ain't comfortable enough to do more than 100 miles without stopping to stretch out anyway.

Re: How miles on a tank of gas

Many long distance riders add tank volume, usually with auxiliary tanks out back somewhere, but some add a couple inches of height or width or both to the stock tank. The Monster dowsn't have anywhere up or sideways to go. And down is all airbox.

Looking closer though, there really isn't much that's gonna be gained by losing the airbox and using individual filters. I don't really plan to ride far on the duck anyway. Just a thought (which killed a good half hour at work yesterday).

Re: How miles on a tank of gas

I think I have run my S4 out at 114 and 125 miles. Your bike probably get better mileage, but I would be looking for fuel around 110 miles.

I usually get about 120 when the light comes on, it is an 02' 750s that is completely stock, how do I get 200 miles a tank? is something wrong with my bike, I thought fuel injection would give better gas mileage.

depends on a lot of things. Before my 600 mile service i was getting around 120-130 or so. Afterwards it went up. Not sure how much but I managed 130 without the lite coming on but I chickened out. I usually fill up regardless at 125.

Short shifts and easy takeoffs are a great way to extend milage but lets face it, thats no fun. ;D

On my '02 620 Dark I get 130 miles a tank on regular gas. I tried premium and the mileage dropped to 125 miles a tank. I have a short commute (6.6 miles) with a little stop and go.

Well, here goes on some of the why and how. I'm using data from Ducati manuals, so if anybody has some FHE, speak up.

AFAIK, Monsters '00 and later have 4.36 gallon tanks. Earlier Monsters had a slightly different tank, I don't remember the year..
Carbed Monsters have the light go on when there is 0.92 gallons left, meaning you use 3.44 gallons before the light comes on.
FI Monsters have the light go on when there is 1.59 gallons left, so you use 2.77 gallons.

cc, I assume you're referrring to Daffe's post, getting 200 miles before the light comes on. He's got a carbed 750, so he gets 0.67 gallons more than you to run on before his light comes on. Plus, he weighs about 100 lbs, so that's likely another significant difference. Riding style enters into it too.

As another point of reference, there's some folks who posted on this thread that had '02 S4's, running out of gas at 120 miles or so. I routinely get about 130 before the light goes on on my S4, and have gotten 150 without running out. Very odd.
