while generally highway markers will get you within 1% for sure, but they are nothing I would trust, I would put more faith in a gps measurement. only mile markers that I "trust" to be accurate are thise that are posted with a "begining of measured mile" sign and at the end a posting with "end of measured mile"
Maintenance and Gas Mileage
So I've had this 03 for about almost two years now. The only thing I miss about the 07 I had was the gas mileage, it got 50-55 consistently, no matter how hard I was on it.
My bike has at least 25K miles on it. Just going through and seeing what the culprit is for my poor (33-38 mpg) mileage. I get the same mileage when I ride hard as when I take it easy (at least it seems that way).
Maintenance Items - Date of last check:
Air Filter - Stock, changed in August, still clean
Oil - Amsoil Full Synthetic @ 19k miles, below F and L.
Coolant - Unknown, topped off last week.
Valve Clearance - Approx. @ 15k miles by PO
Chain and Sprockets - 2k miles, Last May, 15/44, Dupont lube weekly, EK Gold 420
Chain Slack - Checked weekly
Spark Plugs - New NGK plugs in Sep. 06
TPS - Set by PO, never messed with
Idle speed - 1.2k rpm
TRE - Done in September '06.
What else can I be missing here? I feel like it's running a bit rich.
Bout to drop the engine for a cam swap, busa pistons, new plugs, valve clearance check... might as well get some more maintenance items in while we're at it.

For what it's worth, i have an 03 with a full exhaust. I got a PCIII and threw the maps from the PC website and took it to the track and lost a consistent 1.5 MPH. I had my laptop, so I zeroed out the maps and my 1.5mph returned instantly. So I drilled a bung into the exhaust and threw my wideband on it and found that the factory tune is pretty good at WOT, and a little rich at part throttle and idle. It runs "good" when it's cold, but when it's warm, it's a little rich, so I leaned it out. It's now lean when it's cold and good when it's warm. Anyway, it's tuned pretty good now and I only got a few mpg out of it. I ride "spirited", but not too hard (I haul from 0 to 5mph over the speed limit). I get 38 - 45mpg. I probably average 43mpg.
So I have no idea why the '03s get worse gas mileage. It could be some sort of difference in ignition timing? I really don't know. I also haven't heard of the throttle body synchronization. Was your '07 faired? The aerodynamics would be better on a faired bike.
Oh, and if you wouldn't mind, please send your signature pic to me or post it! That bike looks GREAT! alex(dot)lauerman [~a~t~] gmail. Sorry for all the anti-spam characters in the last sentence, but you get the idea.

Sure. I have an innovate wideband that I use for my car which I rigged up. I duct tapped the wideband to the handlebars and ghetto rigged it up to the battery (it wasn't a clean install by ANY means).
I took off my muffler and drilled a hole where i wanted an O2 bung and then I had my friend weld on the bung. I could have also done a "down the pipe" thing, but I figured it would be easier just to put a bung on it.
Then I rode around and made several short trips watching the wideband at different throttle positions, engine temperatures, and a few different atmospheric temperatures. Here is my map, as you can see the biggest changes were at the very low throttle. The funny thing is EVERYONE said I would be lean with a full exhaust and no power commander, but I was right across the board!!! I guess that just just shows how "immature" engine mods and tuning is for the SV650. It's funny how many motorcycle riders throw parts at their bike without understanding them (don't get me started on TRE's). The X-axis is throttle position and the Y-axis is RPM.

Cool. I washoping it was somehting you had rigged from an old O2 sensor, a DMM and some butcher's twine for $42 (plus notepad and pencil) but that's a pretty nice setup too.
I would have, but a normal (narrow-band) O2 sensor only reads from like 14.5 - 14.9 AFR (which tells you very very little -- only useful for fuel economy and it'd be a real pain to tune with that little information). A wideband O2 sensor reads basically all AFRs. I tune for ~13.2:1 at WOT and 14.7:1 while cruising/idling.Cool.

ya, Iknew the narrow vs. wide business, hence my interest.I would have, but a normal (narrow-band) O2 sensor only reads from like 14.5 - 14.9 AFR (which tells you very very little -- only useful for fuel economy and it'd be a real pain to tune with that little information).

That's a pretty cool setup though- certainly cheap enough for a couple guys or club to go in on together.
What would be smart is to get one (maybe with an exhaust clamp) and rent it out for $20 a day or something. I suppose by the time you got it paid off, someone would break it or steal it or something.
It'd be a lot more worth it if I actually gained something worthwhile (like 6HP) from doing this. With a very lightly modded bike like mine, I'd definitely recommend against buying one. I definitely wouldn't have bothered if I knew what I know now.

That's the map I'm currently using. Dynojet's stock exhaust/filter map that I modified (they were adding fuel at the lower RPM ranges) and zeroed out anywhere there was fuel added.
And I just figured out how to copy and paste into the dynojet software. With my modifed map I got 43mph on freeway and 38mpg in town.
When my bike is back together I'll try your map and see if it helps any. My butt dyno hasn't been able to tell in any loss of power.

That's the map I'm currently using. Dynojet's stock exhaust/filter map that I modified (they were adding fuel at the lower RPM ranges) and zeroed out anywhere there was fuel added.
And I just figured out how to copy and paste into the dynojet software. With my modifed map I got 43mph on freeway and 38mpg in town.
When my bike is back together I'll try your map and see if it helps any. My butt dyno hasn't been able to tell in any loss of power.
Preliminary report on Cyphear's map. The bike has been up and running since Tuesday night. I loaded the map right before I went out for a ride.
I've been riding pretty hard since Tuesday night, lots of stops and goes (breaking in new pads), "testing" out acceleration and speedometer error, etc. This tank has not been babied at all. Filled up the tank to the filler neck, did the math, 43.4 MPG! If my odometer is reading low like I think it is, this is a good sign.
Things that I've changed since the previous setup:
New brake rotors and pads (less front brake drag)
New tires (Odometer may be reading low, have not measured against mile markers yet)
Longer exhaust pipe w/silencer insert (more back pressure)
My butt dyno has not been able to tell a difference in power.

On my 01 I always got around 40-45 mpg until i brought it out this year i dropped to 32- 35 all the time?
Update:
Looks like my Odometer is reading low ~3%. Must be because of the frest 120/70's. Filled up again today, 47mpg city mileage! I'll find how highway miles go tomorrow.
So far so good!

So if I understand this thread correctly... your MPG improvements seems to be coming from your dynojet mappings?Update:

Sorry for asking a n00b question, but are dynojet and PCIII mappings the same "format"? In other words, mappings copied from a PCIII can go to a dynojet module? I'm a bit confused.
I heard that you can tell if you're running lean or not by looking at the header coming from the front cylinder - if it's turning purple/rainbow-y, then engine is running lean.
I currently get about 40MPG mixed riding. I want 47MPG in the city too!!!
*edit*
ok, sorry. So, DynoJet is the maker of PCIII. See, I'm that confused :S
anyway, so is it worth it to get a PCIII for my 05 SV (~$300) if I'm not planning to track/race my bike just for some MPG's?
As of right now, my engine is probably running a tad bit lean when cold, and good when warmed up.
You can get a PCIII from Blair of sv-racing-parts for less than 300, PM him for details. I got most of the stuff on my bike from him. As for whether it is worth it or not.... probably not... you'd have to put on a LOT of miles to get the money back. The only reason I used Cyphear's map is because we both have '03 bikes that got meager gas mileage. They probably came off the same line. Your '05 stock ECU is probably a bit different than ours. I was planning on getting a custom full system, hence the need for the PCIII.
Cyphear used a wideband sensor to check A/F ratios. The only way to truly tell is with an A/F sensor.
You should try checking tire pressure and running some Fuel Injector cleaner through the system to see if it helps or not.

Third Tank: ~43 mpg (went top speed a few times)
Fourth Tank: ~46mpg
So far so good!
Just changed the oil and lubed the chain, hopefully this next take will hit 50mpg.

On my last trip to NJ, I averaged about 51 MPG with odometer reading around 80 mph for most part.Third Tank: ~43 mpg (went top speed a few times)

In the city, on my commute to work, I usually average about 48 MPG. I have a 2006 Naked with about 7500 miles...
I would not recommend a PCIII to anyone, unless they are looking for every last horsepower or will ride for a very long time and want 3-4 MPG improvement. You must dyno tune it by a knowledgeable tuner (there aren't many IMO) if you want to gain HP or take it to the drag strip to see if you gained power.
Well, I had another eureka moment. Cyphear's map is adding more fuel than needed for my bike since he has a full system. So I brought up Dynojet's map for a Slip-on plus K&N filter. Turns out, that map is adding even less fuel than Cyphears at certain power bands.
I used Excel to take the lower value of the two maps. This is the new map I'm using:

I'm getting ~52-53 mpg on the freeway (75mph average), and ~46mpg in the city.
I used to only get 35/41 mpg city/freeway. ~25% increase in gas mileage... not too shabby.

Update:
On the way to Deals Gap, all freeway miles nets 56-57mpg, cruising along at 80 indicated (76mph according to GPS.) Got ~46mpg around Deals Gap staying in 7k rpm on most of the roads.
This new map is GRRREAAAT!

That's great.
Does it ever "feel" lean anywhere? I think you know what I mean, but if you dont, you usually feel a loss in power at a certain throttle position.
