I would go with a 2020 to make sure you have all the fixes. I never had any issues with my 17 but the 20 seems more refined. The M8 is a better touring platform for me anyway. The extra torque down low makes mountain riding 2 up and loaded more enjoyable. You can't really go wrong with the Rushmore 103. They were good motors they just seem under powered in stock form. The other thing is the boom system changed with the later model M8's which is a big improvement over the previous versions. Screen is brighter, faster to boot up and operate and the UI flows better.

Even if you score an early M8, the oil pump to fix any potential sumping is about $112 bucks and the vent to cure trans oil transfer is around 3-4 bucks by itself and around $38 as a kit.
Sure, it might take a few dollars more to get the oil pump in (adjustable push rods/gaskets) but it's really easy work you can do yourself - even better when doing a cam upgrade which is what I did. My original 2017 oil pump was fine the 30K I put on it before upgrading the cam...

I am looking at a new bike, going from a 2012 UC to a Rushmare RG. After reading hours of threads I am left wondering should I get a 15-16 and avoid the M8 and sumping issues. Did they all have issues or was it just a few? Did the mothership get it fixed and what was the cost. They are a bunch of great very low mile bikes in my area from private parties that I can pay cash for. Not really loving the idea of a 32k RGS from my local dealer.

In my opinion the Roadglide Special is not worth it unless you really want an all black bike, as far as the power, not a noticeable difference between the 107 and the 114. I never owned a TC, I went from an Evo to the M8, thought I would keep both, my Evo was built pretty stout, after a month I sold the Evo.

A 1K cam install fixes that power drop off in spades in the 107.

17 Roadglide 27 k on it. Red shift 468 cam and updated oil pump. It has never sumped or transferred. Runs awesome but uses too much oil for me. Now its big bore to get rid of the oil consumption issue or sell it. I was just as happy on a 103 Heritage, and I could blast out to Sturgis and not have to carry a quart of oil.

So y'all are saying that 7 cubic inches more don't mean chit. So all those big bore kits sold to bump the 103 up to 110 was false advertising. I have my 103 TC and my 114 M8 both in the garage. Cams, pipes and tuners on both. The M8 is a beast, does everything well. The TC is just ok.

a lot more to it than that and it wouldn't have made my Road King more fun and enjoyable overall than my Road Glide Special...and feels great to not feel the need / compelled to spend a dime on the powertrain
