You also may have dragging brakes or really get on it like a jackrabbit to get it down that low?

Re: Fuel mileage
MPG is relative to speed, the faster you ride, the MPG goes down. Ideally the best MPG should be at about 55-60 MPH except for the 6 speeds.

Re: Fuel mileage
25 is a bit low but the 40 is a respectable number.

I have V&H pipes & the stage 1 as far as I know. Otherwise stock. I think it is the 88/1450 engine. (Sometimes I get dyslexic with the numbers).
 This is based on a mix of highway riding, country back roads, and some town. The high figure was a lot of highway, back & forth to work in light traffic, the low, well, that may have had some hot dogging mixed in with some stop & go. That is about as documented as I get. Looking forward to seeing the other results.

Should I expect this to improve when I change the pipes, ect? I've always had the pipes changed before delivery, but that's not the way this one worked out. Thoughts?
High 30's to low 40's are probably the best you'll ever see on the new bikes. |
