Fuel issue looking for some help.

Looking for some inputs on what I should start looking at to see whats going on with my bike if anything.

Bike: 2004
Newer bike to me with 8K on the clock running an unknown map on a PCIII with Satos Low Mounts. Getting poor fuel mileage ~ 24MPG. Very slight smell of fuel some times at idle. The smell is hardly noticeable.

Runs good no issues that I can notice. No excessive black build up at the exhaust pipe outlet and certainly no smoke or smell at the exhaust. Tires have the right pressure chain in good shape and lubed.

I understand I should get better mileage (I am pretty bummed running out of fuel at 105 miles on the OD) that coupled with a sometimes minor smell indicates that I am either running to rich or I have a small fuel leak. Not knowing the map lends some uncertainty about the tune.

So where should I start looking?

Do you use your choke to start? You're sure it's all the way in?
Someone just recently had that issue too and that's what it was.

Get a custom map done soon. Just because you can't smell gas or hardly smell it doesn't mean when you pour on the gas while riding, you aren't shoving it out of the tail pipe.

Load up the dynojet program and get your 9V adapter and read your map. This would be a great start.

Jon no I use the "choke" or high idle to start the bike and never leave it on. Even if I did it would not cause a rich condition as its not a choke but a high idle position.

Mad good point I have never used the PC before and will down load the manual now to see how to use. I wonder if I can read the map at all or if its a bunch of jibberish code???? Time to educate myself. I have already downloaded a map from their website that I could try.

It looks like a bunch of numbers at first...just make sure what is loaded has a name or label. There are plenty of maps out there on the dynojet website too, just to get you by until you can scheduloe dyno time.
