31 will work just fine. Have 30,000 miles on set-up all over this country. Works great NO belt change. Speedometer's are always off from factory a little slow, 3 miles I think. We are always 2 up & fully loaded. Best change I made. Mine is a 2016 also, so I know it works. If no warranty ,put a Power Vision on it & fix speedo & many other things.

Something to consider..... if you lower RPM at a set speed, you will lower torque as well. A 200-300 RPM drop will reduce torque by 5 to 10%. Since torque maintains your speed it may cause a loss of MPG even though a lower RPM is achieved. A reduction of 500-750 rpm (4000 to 3200 or so) would definitely increase longevity of engine nd drivetrain parts.
But we aren’t pushing s skinny Sportster thru the air.
The Tri Glide is NOT th most aerodynamic in the HD lineup and consistently gets bad reviews for poor milage. I ride a trike because I want too, Not because I have too. So MPG is not a concern, but passing and staying safe in traffics iS! It is absolutely necessary to ensure my safety and the safety of those around me on the highway that I can maintain the speed of traffic. Torque maintains my speed, not MPG or RPM. But RPM DOES affect torque and performance.
That's something I learned after a few months of TG ownership. Keeping the rpm up around 2,700 + actually seems to improve the mpg. But when cruising at 75 mph it gets the rpm a bit higher than I'd like. It just sounds and feels 'busy' and makes the ride less pleasant. But it does work to make me keep my speed down so I guess it's not all bad.
The first couple of years of the Tri-Glide they were geared the same as the 2 wheel touring bikes. There were a lot of complaints about lack of torque. Subsequent years HD lowered the gearing on the trikes, which is good for most on the Twin Cams.
What surprises me is that they kept that lower gearing with the M8's. The M8's have better torque, and down lower, than the Twin Cams. I would think going back to the 2 wheeler gearing would work well, or at least half way in-between, like what Bill did.
One day, I don't know when, I will get an M8 Trike. When I do, changing the gearing will be one of the first things I do.

I think my Freewheeler M8, 107 cu. in., runs great on the highway. That is with a K&N air filter in the stock airbox & a external breather of my own design. If I had known about the DK Custom air cleaner before I got my K&N, I would have got it.
For some reason, mine seems to run better than most. I was told that again today, after the dealer did the clutch recall fix & rode it a few miles on the highway to run it thru the gears.
I would think the 114 is even better.

What HD really needs to do is put a higher 6th gear in the trikes. Either that or install a 7 speed with a higher gear for the highway. That way you would have the lower gears for taking off and pulling hills and the high gear for highway flying.

I've known a few guys that have run the Baker 7 speed. Just last week was talking with a guy that's had one in his last 3 bikes....including one in his 2014 Tri Glide.
They all love them. Lower 1st gear, better spacing between the gears, and 7th is the same as the 2 wheel bikes 6th, without giving up the lower gearing for starting out.

A good tire shop should have a chart or a program to tell what size goes how far per revolution and speed it changes from one series to the other. For me I am going to try 70 series tires possibly a 195X70 15 if available. If they don't work out my utility trailer will have new tires. Changing tire size is the least expensive way of playing with the gearing.
