I really don't want to open a can of worms here but over the last month I averaged a little over 120 mpg. And I worked hard to get it.

170 lb. rider at an elevation just under 5,000 ft with 90 degree temps. 15-50 sprockets. #128 main jet with the pilot screw 2 and a half turns out. Few hills and never more than 40 mph. No traffic, rural hardtop roads and very few stop signs.

The only reason I tried to achieve these mpg numbers was to see how far I could go on reserve if I really needed to.

I have triple checked these numbers and yes I know how to measure mpg at the pump.

I guess my point is that your reserve fuel could take you quite a distance if needed.

Respectfully,

Jack

Yes, reserve is a big unit if it is actually available. When I removed my stock tank to install the XT350 tank, I drained as much fuel as I could from the tank (disconnected the fuel line and opened the petcock). Then I took the tank off and attempted to drain the rest by placing the tank on a flat surface and opening s the petcock again. When I really got violent and started tipping the tank and trying for all of the liquid, I got a significant amount more (sorry its been years), but the point is that even with reserve exhausted, there is more gas in the tank and tipping it will get you more gas.
Do I believe your 120 mpg? Yes but to publish it in the real world you would need details, circumstances, and ways to verify. Do I sound like a former research scientist?
100 mpg is easy with careful riding, and a well tuned bike, and 120 might be possible but tell us about it. Congrats in the meantime. Tom

Yes, way to many variables to publish those numbers. I don't doubt a perfectly tuned bike running on a good quality fuel in relatively flat geography and being driven by grandma going to church on Sunday could achieve such great economy. For the rest of us I think an average somewhere between 70-80 MPG is about right. I know for a fact that the 4 full tanks I started with have all gone to the reserve at almost exactly 80 miles. I can set my watch by it and I do the math the minute I fill the tank so I know when I have gone 80 miles. Just two days ago I started with 830 miles on the clock and at 910 I had to flip to the reserve and find a fuel station. Congrats on your findings but I will bet if you followed right with me for an entire ride you will be nearing the reserve pretty close to when I do. 40 MPH is a nice cruising speed but I also hit 50, 55 and an occasional 60 on most of my rides.

2006 49 state model. The 128 main jet is for California emissions. The change from a 126 to a 128 works great at an elevation of 5,000 ft. Might have to go to a 130 this winter.

In normal riding I get about 80 mpg. Just wanted to see what the maximum fuel economy could be if I ever needed to extend the reserve range. 35 mph in 5th gear seems to be very fuel efficient.

I too have an '06 (love the color).
I ride entirely on the street and consistently hit reserve at 120 to 125 miles.
Every tank I get between 92 and 95 mpg.

The engine hasn't lugged down one bit with the 15 -50 sprockets and my 170 lbs. on level ground at 5,000 feet elevation on a 90 degree day. But I'll take down to 4th if I need to. This is not a normal riding pattern for me. I'm just trying to find out how far the reserve fuel could take me an emergency.

I have never gotten more than 65mpg. I only wish I could get 78 suggested mpg.

I haven't got many miles yet to get a good number, but today I put in just under 1 gallon and 82 miles on the odometer since I filled it last time. stock 2005 Tdub
