If you want to see what some others report for fuel mileage, try www.fuelly.com. On its left is a "browse vehicles" and when that opens you can browse motorcycles. Then you can find Suzuki, and the model. Personally, I think it ought to be getting at least 50 mpg, but carburetor jettings and driving habits have a strong influence on mpg.

You can click on the fuelly badge in my signature block, and wander around from there, too.

I average about 36mpg, but the vast majority of that gas is spent to and from work.  5 miles, 4 stop lights, 6 stop signs.  The best I've seen was around 55mpg, all highway miles.

I avg about 44 to 45 mph most times, but I know I'm rich in the mid range on my tuning,  when I was fine tuning my setup I lost one of the washers that was sent in the kit from Lancer and that made me abit to rich in the mid range which is where you are in most cruise and highway riding.  I'll just deal with it for now until I get the upgrade carb from Lancer in the next few months, then I'll get her tuned properly.  Plus I'll be doing a chain conversion with a 17/43 which should help with my mileage as well since most of it's at 70 mph around here in the country to get anywhere as it's all hwy and a min of 20 to 30 miles to the nearest real store.

The bleed holes don't do anything on our carbs.  The bleed holes operate on carbs that have an "air screw" to adjust idle air iinstead of idle fuel.  I have tried both with and without bleed holes on my carb, and with an O2 sensor in my exhaust so I could read the difference, and there is none.  On our carbs the only metering is through the size of the small hole at the tapered end of the jet.......the bleed holes don't do a thing as they are surrounded by the aluminum carb body and there is nothing that can flow into or out of those bleed holes.

On the third page of the following link - there is a diagram that shows how the pilot jet has both fuel flowing in the bottom, and air from the air bleed screw is mixed through in the Pilot Jet.  There is also a description of this on the section that talks about the low speed operation in Section 3.1.

My overall average fuel economy on my 05 has worked out to be 41.9mpg. Most of my travel is short in town rides, I think it's a little rich with my setup (147.5 main/55 pilot) running a Memphis Slim w/s and Fishtail muffler with little baffling.

Here's a screenshot from my phone of each time I've filled up since last summer (Makes me think I need to ride more often)

Could be heavy on the throttle!  

I'm getting about 45mpg city, over 50 just cruising.
