I believe it is all stock. Stock ac and head pipes and not sure on the cams but I believe stock also. I was hoping when I added the map that would help but it stayed the same mpg. I am interested in any upgrades the would help milage and longevity to the motor.

I think others will chime in on this one but I would put a high flow air cleaner on it and re tune your map through fuel moto. something is off. @ Stage 1 it should be an easy fix to get it running right with the mpg up unless you are heavy on the throttle

the thing you have in your favor is fuel moto is great about customer service- bypass all of us and our guesses and call them on monday. let them walk you through this and then post back with your results

My all stock '13 RGU would get 50 mpg riding the U.S. highway system, traveling 70 mph on the interstates I got about 46-48 mpg. Haven't been on a long trip yet with the open air filter and FP3 tuner but sure it won't be too bad.

I put a power vision map on from fuel moto and have rinhart exhaust. The milage was or has been bad since I got the bike last fall

First order of business is to get rid of the stock down pipes and go CAT delete.

Custom tune with the PV by data-logging and accept the changes to another slot so you keep the Fuel Moto tune and the stock tune.

My 2012 Ultra Limited was as bad if not worse than yours when I first go it. I installed a SE air cleaner, V & H down pipes "X" with Rhinehart slip on's and PV from Fuel Moto. With some custom tuning using the PV I was able to get into the mid 40's for fuel mileage, so good news there.

I never could get the engine to make the power that I thought it should have been due to the emission cams they used in those years. Instead of a cam upgrade I sold it instead......Cliff

It's not just the hard parts- but how they work together -or don't- and the altering of the fuel delivery and spark timing.

performance results depend on a systems approach.
it is not unusual to see a catalog shopper buy one part which "makes horsepower at 5000 rpms"...at another part which makes torque at 2500 rpms and wonder why they aren;t flying through the air with all the advertising hype.

You may have made more power with other cams, as you may have with headwork or displacement- but higher lift, longer duration cams take their own penalty is reduced mpg and reduced service life.

some models like the twin cooled twin cams and the M8's can now use more cam and higher compression due to more controlled combustion chamber temperatures.
resulting in that balance of cost/power and reliability in which we only get to choose 2 and the third is a result of.
