A number of people ask me what I get for mileage and while I understand and appreciate the importance of good mileage and a good tuning, I explain to them, 'I did not buy the bike for the mileage'.

I'm pretty sure none of us were fixated on fuel economy when we bought any of the bikes we've owned.  It is somewhat telling though that a much larger 4 wheeled vehicle with all the comforts of home can often do better than a Harley.  Hmmmm.

The only reason I monitor fuel mileage is because it's a good indicator of how well the engine is running.  If you average 40 mpg in your normal riding for instance, and suddenly you only get 32 mpg, the bike is telling you something and you might want to do a little checking.  For long distance riders, it's also nice to have enough fuel mileage to give a decent range.  Personally I tend to look for any excuse to pull over after a hundred miles, but many hard core types try to maximize miles between stops.  The difference between 40 mpg and 32 mpg would be significant to someone like that I would imagine.

Jerry, I agree with you. When i first got my bike I immediately put on pipes and a tune. I was only getting mid to high 20's for mpg and when I went back to the tuner he convinced me it was my riding style which admittedly is very aggressive. about 2 months later my brother in law bought the exact same bike but different tuner and when we rode together he was getting low 30's and we were never a half a mile away from each other. It was time for a new tuner for me..

I have always gotten around 35mpg when riding around town with some highway.  Not as good as others but ok.  I did not buy this bike for mpg.  On the highway it might hit 39-40 if I don't ride too fast.  I found out it was me and not the bike. When I was riding at one off the CVO GTG my mileage went up to 44-45.  The riding in a group kept me from hitting it hard so my mileage really shot up.  I just can't get away from trying to stretch my arms.

'15 SERGU, 24D cams, fullsac head pipe, 1.75" fullsac cores, tuned by one of the best, loaded with gear and my 230 pound butt I get right at 38. It doesn't seem to matter how hard I run, or if I'm 2-up, poking around town or 80+ on the interstate I always average right at 38.

As an indicator of state of tune, I track my mileage.  My '12 CVO SG with 57H cams gets about 40-42 on 10% ethanol 91, but on 93 octane pure gas I get about 46.  My hp is about 101 and tq is about 113.  TTS tuner by GMR.

A few years back coming back from the Pala GTG I started getting terrible fuel mileage like down in the 20's. The next day closer to home the motor blew up. My problem was the crappy cam bearings let go. :'(

When I first got my SEGRU I did not get good milage.  It was around 180 miles and would take 5.4 to 5.6 gallons.  Much worse than the other CVO's I have had.  As the miles got put on the milage went up, around 200 miles a tank and the same amount of gas.

With about 3500 miles on the bike Doc in FL tuned it, with my fullsac 2.25 baffles and fullsac head pipe and the TTS Tuner.

I avergage 220 miles per tank now at 5.2 gallons.

Trip I just did to FL and back with very little interstate but good 4 lane at 65 mph average I was getting 230 miles per tank and 5.1 gallons.  So right at 45 mpg.  Out west running 80mph I would get 200 miles per tank and 5.2 gallons about 38.5 mpg.

Much over 70 mph the gas milage goes away fast.

That said my CVO King with the built motor, head work, pistons, injectors, throttle body and cams and so on, gets much better mpg.   Running 60 to 65 I average 49 mpg and a few times over 51 mpg.  I have gone 270 on a tank in that bike.  Again tuned by Doc.

Jason at C&S Speed Shop in Metro East St. Louis. He did the build and the tune. I have had 4 bikes tuned by him and all have turned out fantastic! He's a member here also.

Not the same bike and this is probably like snake oil but when I first had my 14 CVO ultra the milage was around 38 mpg.  I am a conservative driver but that mileage actually went down to about 31 mpg.  The bike is stock and though it ran fine, the power didn't seem as robust as when I first got it.  I put in a full can of Tehran entire fuel system cleaner into the tank and now the snake oil.  Seat of the pants dyne improved and my mileage actually increased to around 42 mpg.  Now what was probably the real reason for the change, in the spring around here, we are still using winter blend fuel and then suddenly we get summer blend.  Maybe the cleaner made a difference as the fuel obtained in the spring probably was,t the best. Anyway, no science but just my experience.
