39mpg.

That's with 80 miles of interstate riding at 70-75mph (according to the speedometer). The rest of the miles are on 2 lane highways with traffic lights (40 - 50mph speed limit).

I just have to keep my eyes open for gas stations after the 150 mile mark. You guys are lucky to hit close to 200 miles before a fill up!

My latest fill up was 157 miles. Required exactly 4 gal of gas.
This is not bad considering you're riding in the rev range where the bike runs pretty rich.

I fully understand your wanting to stay mostly stock, but you may want to consider using iridium plugs. If nothing else it will give a chance to see a comparison between two different plugs and any difference in combustion, gas mileage and power. Even a little more air to even out the richness may help. Keep in mind that your slip on may contribute to your mpg as it is not as restrictive as the stock exhaust.

It won't hurt anything.
