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.

Hey Joy, it is good to always check, if mileage suddenly drops a lot say 6-8 mpg from average over a couple tankfuls all things being about equal it usually indicates problem, i.e. plug(s) may have gotten fouled or such; which I found when I recently changed my plugs, could not believe it went up by that much!

Solo I get around 42 MPG(39-45 depending on the wind)
2up Drop by about 2-3 MPG

If if go any faster they drop in a hurry!

OK, I've had my new SG a week and have 940 miles on it, and my MPG is only 37. Granted, it may still be 'tight', but I would have expected better (not worse) MPG than my 5 speed. I also haven't changed the pipes or A/C. Maybe that will help? If I had been riding my Ultra the way I've been riding this one for the last week, I would have expected ~45 mpg. Anyone else seeing worse MPG from new bikes? 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?

why would you expect better? If we were taking trucks would you getter better mileage from a 302 or 454? If you know the answer to that why would you expect better from a 96" than you got from a 88"?

High 30's to low 40's are probably the best you'll ever see on the new bikes.

I also had a '03 mutt glide (started as RG then I converted to EG) with 95" stage 2 that got 42-43 mpg. That bike would do power wheelies without dumping the clutch. That's why I didn't expect it to get worse just because they added 8 CI. I also run about 400-500 RPM less at my normal cruising speed (74 mph according to GPS, not speedo) in 6th gear now.

I didn't expect it to get that much worse either, but I don't know many people with the new 96's getting that great of mileage. It's not too bad all things considered. Rpms doesn't have much to do with gas mileage as I understand it. It takes less gas to run an engine at 3000 rpm in 1rst gear than it does to run an engine 2200 rpm in 6th gear

LOL, Newhdfan74, I agree about the checking the mileage, it's a great way to monitor & catch problems early on.

Thanks.

I agree. I have an 06 road king w/ screaming eagle pipes. I get about 31. I do everyday riding mixed between highway and street. My bike has a carb. My bike will run out of gas at about 125 miles after fill up, then I switch to reserve and go for another 20. I don't run it till its out of gas.
