Exactly. didn't buy it for MPG just enjoyment. In the 4 yrs I have owed it ,have never checked it,

Thanks for all the replies, guess I will just deal with it, sounds like I'm pretty average mpg, the last tank was 37 and very happy with that. I always fill it the same each time or least try to. I'm around 2 miles to a highway and that is all I drive is highway, bypass or interstate, I try not to do city driving because of pot holes etc etc.

I ride a 2022 freewheeler 114 motor I average around 35 mpg. My wife’s trike is a Yamaha and she is about the same. Only difference is my tank is 6 gallons compared to her 4.7

So I would say your getting the expected mileage.

Gas mileage

I’m getting 42 consistently on our 23 Glide. She’s new and stick with 1,800 miles on the ODO. Happy with that.

Average 37 mpg. 2022 tri glide with 91 octane, non-ethanol fuel

Depending on how I ride and the conditions, as low as 30 mpg (75 mph, loaded, some headwind) and as high as 44 mpg (staying out of the throttle and below 60 mph).

Several years ago, heading south on Interstate, into a strong headwind...26 MPG. Took me by surprise and had to refuel before I had planned. Found out that day that the barn door we are pushing through the wind is really affected by a headwind! On the way home, with a tail wind, mpg was upper 30's! Again Interstate (72-75 MPH) This was on a 2016 103 TC....(I know it's not the motor the OP asked about...just anecdotal information).

Now, on a '21 M8, best mileage was 48 mpg riding between 50 and 62 on 2 lane roads up in the Black Hills of SD. Worst mileage was 30 mpg on a combination of 2 lane and Interstate with again, a head wind.

So, a SE stage 2 upgrade on average costs between $900-1500.00 according to Google. And based off of earlier threads a M-8 stock bike got 34 MPG and after a stage 2 upgrade got 36 MPG. Thats 12-mile increase on a 6-gallon tank (math for Marines). So, is the cash really worth 12 miles? Think not.......unless you just ran out of gas in the middle of the desert and the closest gas station is 12 miles down the rode.

With a good stage 2 cam you may get a wee bit better mpg, but you ( picking the right cam) will be adding more pulling power

Since we teed up the hornet's nest, let me take a swing at it.

I don't think anyone does a stage upgrade for the MPG. We do it for the performance. I was ready for a drop in overall mpg, but it all depends on how I ride. I typically ride at elevations of 5,000 ft or more. I love the exxxxtra power (torque) I get from my stage 2. For pulling up hills or for passing SMVs it cant be beat.

However, If i'm on a freeway and runnning at 5k or more (80mph), then there might be a drop in mileage.

Regardless of how I ride, I always stop and fill up before I'm on E.
