sooo, i thought my fuel level sensor was bad as it was coming on 50-60 miles after a fill up. i kept filling up at that point afraid that perhaps it was correct and recently went on a long ride - light came on around 60 miles after fill up and i kept going. long story short my bike ran out of gas at 84 miles after fill up. HOW THE HELL IS THAT POSSIBLE? anyone ever have any experience with that in the past? i haven't noticed/smelled any conspicuous leaks - i do have an aftermarket cap (can't imagine that would have anything to do with it) but have no idea what this could be about. just seems nutty
S4R's are thirsty, but that's *really* thirsty.
Fuel return line kinked?
i'll have a look. how's your week shaping up? i think she needs some speeddog lovin
Only 80 miles to a tank? Hmmm.
My theory is the problem lies between handlebars and seat, specifically at the right wrist kinematic process.

Bring her by, your caliper finally came in. :)
cool. i'll be by in the am
Have you let the bike sit for the winter ? Clogged injectors could cause the problem.
No, it's a Cali bike . . . we dont believe in winter here.
That's awfully low. I get about 90 before the fuel light comes on. That's with a heavy wrist too.

ya, i'm bringin her in for some surgery. not sure what the deal is
Hey ugly just so you know, I was kidding when I posted that you were hooning out and using too much gas with the throttle. Just a little joke for youz. But maybe there is something wrong with your bike.
Oh I know what's wrong with it - it's not mine!

No worries man, I actually giggled a bit about it cuz I do ride like an @#shole and figured that could possibly be part of the issue. But even I don't have the skills to make this beast only deliver 20mpg.
My S2R 800 only get 76 before the light comes on. This is also due custom fuel map inside her. Not sure my wallet likes the new mod but my wrist DOES [Dolph]
Maybe you guys need to use the left side a little more and try out, say 4th, 5th, 6th :o gear?!? [cheeky]
Silly question, but how much fuel can you put in your tank? Could the problem come from the plastic swelling, so your tank capacity has gone down?
Wow, I'm liking my M750 more and more. I'm getting 40-45mpg even spending a tank running back and forth on Deals Gap!!!
JM
my tank is metal and capacity is a tad under 4 gallons. i'm getting about 20mpg at this rate - couldn't possibly be how i ride at that point. but anyway, there are gears after 3rd? how do you access them?
Just picked up my '07 S4RS and am curious to see what kind of mileage I'm getting on my daily commute. Shouldn't take long to burn through a tank and I'll let y'all know. I also am having problems accessing the gears beyond 3rd. Is there an overdrive switch? [cheeky]

[clap] I love it!
i know it's no S4, but my s2r get's well over 40mpg, and i ride it pretty much wide open at all times. i'd say you have an issue.

I think you have an issue too. I am hard on my 800 and don't see the light come on until 110 - 130
ya, there's no question that there's an issue. just the weirdest thing. no leak, no fouled plugs, unless my neighbors are siphoning gas from me every night i really can't account for how terrible the mileage is. i used to get over 150 miles per tank on my m900 and would regularly get over 130 on this bike before this started. something no bueno. i blame zee Arnold Schwarzenegger, if he didn't cheat this wouldn't be happening to my bike.
I just got 35 mpg on my S4R.
That's mixed riding with a heavy right wrist. Also bike has termi slip-on's and collector with DP lid and air filter, and pc3 with custom dyno tune. So fueling is almost spot on.
S4RS with full Termis and ECU. First tank gone, light came on at 89 miles, immediately filled 2.9 gallons, 30 mpg or so. That was mostly under 4th gear around town with some spirited blasts. I think that's pretty average for a 4 Valver. I'm sure in 6th at 75 it would be much better.
The best fuel economy example I've ever seen was on Top Gear. PRIUS VS. M3:
Prius More Enviromentally Damaging Than BMW M3 (http://www.youtube.com/watch?v=dKTOyiKLARk&feature=player_detailpage#normal)
I have a 2005 S4R and i was getting a little more than 40 MPG but that is a lot of 6th gear cruising though. Still better then my RSV 1000.
04 s4r, purchased dec. 2003, always gets 40 - 45 mpg.
So you get it checked out yet?
Yeah Jesse, what ended up being the problem?
I can squeeze out ~120 with some good 6th gear cruising, but more like ~90 with the first 3 gears in the mountains.
speeddog is still investigating. nothing obvious at this point. we'll see . . .
My well tuned S4RS is getting anywhere between 35 & 40 MPG depending on how hard I'm punishing the old girl. For the most part I'm seeig numbers very close to 40.For comparison I'm running the DP ecu and full termi system. I suspect that you will find your problem had to do with the FI setup. Once I took my RS to the dealer for a little FI tuning. When I got the bike back she made gobs of power in the upper RPM range but was super rich everywhere else. I was also only getting about 25 mph. It was then that I decided to buy a few tools and teach myself to tune Ducati FI. Turns out all the dealer did was crank up the trimmers 25 points.. DUH can't imagine why it was soo rich..
I'm sure you'll have it sorted out in short order
Cheers
Mike
just had it dynoed a few weeks ago. fuel delivery looks/seems ok and the tweaking made her run like a lion. running rich enough to offer 20mpg would be next to impossible as it would run like crap and be spewing black smoke i would imagine.
for reference . . .

Minor delay, it fouled out the horizontal plug... :P
Squared that away.
Just took it out for a freeway loop, essentially my regular commute.
58.5 miles, 1.488 gallons: 39.3 mpg.
Well within normal range for an S4R.
My S4 will get ~45 mpg on the same loop.
Mileage is reasonable.
The fouled plug isn't.

well there ya go. i wonder why a plug was fouled. probably hanging out with other bad plugs in rich engines . . .
Nice!
I just did 123.4 on 2.795... 44.15 mpg (mostly highway) on my S4RS with Jesse's old Termis (cut up and shit... thanks again dude, what a good deal $30!!!!).
Glad to hear it's running better. No more wounded Duc.

Mike : What references did you use to teach yourself to tune your FI. On the brain scale how much did it take.............Thanks

i shoulda asked for $40. i knew it. well, when i get her back let's go split lanes when the 405 shuts down! that's some pretty good gas mileage for that bike man . . . still running stock ecu?
Yeah, still stock ecu... I put clip-ons on her and rode Malibu a ton today... heading to NZ to see my girl for 5 weeks starting Wednesday, so most likely we'll have to ride together after I get back in August.
I am real good about eking out great mileage on the freeway (little to no braking, smooth throttle input, lotso 6th gear...) so that helps to offset the canyon jaunts.
P.S. $40 go to hell. What a ripoff! Haha
hahahaha. sounds good man. have a great trip! call me when you're back state side and we'll carve up some canyons . . .
