I'm toolin' up and back at 70 mostly, ok I do slow down when the cages get too close together.  

If you click on the "Fuelly" logo in my signature, you can review the fuel mileage on my S40, with just a few comments. According to them, my overall average is in the 55 range. I figured it once by taking the average of my fuel economy readings. Fuelly apparently figures it by total miles divided by total fuel, and gets a different answer.

The reason I said modifying the jets results in a motorcycle illegal for road use is that the Clean Air Act forbids modifications that increase emissions, either of exhaust byproducts or of noise including intake noise. That prohibition includes not only mechanics, but owners. It does not matter if the resultant emissions still fall within limits - if they increase from where they started they are illegal. We all know those Federal laws are neither observed nor enforced, but they still exist.

Would you be so kind as to define "100% gasoline" for us? Does that mean it has no additives at all? Including the Federally mandated ones designed to keep intake valves clean? And remembering that gasoline is not a single compound but a blend of dozens if not hundreds of different hydrocarbons? And that its formulation varies depending on season and location?

And no ethilene (alcohol).

Hey Bill,
Dija check the MPG poll lately,....hee hee  

Did you ever hear about the 2 old guys that bought identical cars........aw, forget it, you didn't

I think "most" tell the truth on MPG, but some don't,...it's always been that way.

there's only 12 people involved in this thread so far, including myself with this comment. 25% liars...idk what to say.

I think Bill is the only one that accused people of lying on the poll.

I just know of those that always round out the numbers, like 1.2 gallons becomes a gallon,........and 1.7 becomes 1 1/2 gallons.

And then there are those that always give their best ever mileage as gospel.

They may not be. I have recorded three over-70 mpg tanks, and 13 over-60 mpg tanks not counting the over-70 ones. I have also recorded an under-40 mpg tank and 7 under-50 mpg tanks not counting the low one. Most tanks cluster in the 52 to 56 mpg range.
According to Fuelly (in my signature block) my average is a little over 55 (I didn't exactly cite it, because it will change whenever I get the bike out and fuel it again). I could easily have checked any of the blocks in the poll by "cherry-picking" the one I wanted. Perhaps I, too, could be a proud member of the Liar's Club.

If you really care, you can click on the Fuelly logo in my signature block (or the one in several other signature blocks) and review each recorded mpg. You can also see what happened when I tried the "white spacer modification" and why I put the spacer back in. By the way, I have no idea what jets may be in my carburetor. The bike is box stock, purchased new from a local dealer. I have removed the cover over the pilot screw and played with the adjustment, but couldn't really notice any difference. My bike has never backfired on shut-down, and only backfires on deceleration infrequently.
