Back when we had "real" gas, and I ran the stock Keihin CV carb (#45 pilot, 185 main), with SE air cleaner and "H-D by Kerker" 2 into one exhaust, I averaged 50 MPG. This was a heritage Softail, ridden solo by a 150# rider. I would sometimes see as high as 55 on a trip.


These days, running E10 through a Mikuni HSR42 carb (with "mileage kit" installed) and a windshield, I'm averaging 42-45 MPG.

 

I average around 48 mpg.

 

I get about 38 but I have a bigger motor than y'all ;^p

 

after reading the post I went down to the station and filled up 3.8 gallons and only 107 miles. I have a front wheel drive speedo with a 21x3.5 spoke i wonder if that throws my MPH and MPG off?

 

Download a GPS app on your phone and check it that way. You'll know if your speedometer is lying.

 

Around town, with a fairly spirited throttle hand, I get mid 30's. Highway can get into the high 30's, but I also saw low 30's on the Texas trip during one stretch where I was really moving along into a vicious head wind.

 

Consistently 35 almost NO matter how I ride. in town or hwy either.

If the bike is running rich would that be an issues? Also here are some pictures. Not sure what you can gather from them.

 

You can gather you're in SoCal with a scoot that clean..

You still have a little engine Twinkie Boy, but there is a reason why I have a extra fuel tank in my saddle bag, good MPG is what 30 mpg?
