OP, while there may be issues with the MM FI set-up, the other issue is with the cam chain tensioners. Ask the seller if they have had the tensioners check at regular intervals. The stock tensioners have a tendency for failure. I got lucky, mine lasted almost 50,000 miles before a catastrophic failure. This system of tensioners were used up until 2006. I was lucky in regards that this failure happened at start-up and I shut the bike down before any major damage was done. My 2000 RKing is going strong with 100k miles.

I still have a 2000 Road King Classic that had MM fuel injection. Had since new, currently 75k miles. Did a Stage 1 with air cleaner and True Duals early on. The early Twin Cams had issues with the cam bearings and cam chain tensioner failures. Before any problems developed I switched to new bearings and gear drive cams at about 5k miles. Also installed a 6-speed tranny around then too. Added a PC III to smooth the power delivery at about 10k. Bike ran well for 50k miles. I would occasionally have to reset my hot and cold idles, but it was no big deal.
Then did an 88 to 95 conversion at about 60k. After that, I couldn't get the MM fuel injection dialed in, and it ran way too lean and hot. So, I debated about switching to a carb, but decided on the S&S VFI fuel injection replacement. Had a tough time finding a qualified S&S tech to correctly tune the fuel injection. But after finding one, it has run great the last 15k miles. My dyno numbers after the VFI was installed were 88 hp and 98 tq once dialed in.
I never had problems with the known early Twin Cam issues, but on the other hand, the mods done probably avoided them. The bike continues to look and run great, and remains a keeper for me.

M & M fuel injection is fine.
My opinion is that very few people to include techs want to read the one chapter in the Harley service manual.
Almost all failure points are reported at this time.
Plenty of bikes still on the road.
The M & M system was used from about 1995 to 2001.
M & M is still used on expensive cars and trucks.
The reality is that even a carb is not common for younger dealer tech.

I bought my 2000 Ultra (EFI) new.
H-D extended the warranty on the cam bearings to 50,000 miles just in case the bearing failed.
I had the T/C 88 upgraded to the "95" Big Bore Kit at 39,000 miles so it got new bearings and new cam tensioners. A GREAT improvement in torque.
This bike ran fine until it had 75,000 or so miles on it but go to where hold steady RPM's was impossible, and you could feel the bike "surging" at any speed.
I had the new S/E Hyd Cam Chain tensioner kit installed at that time and began searching for the reason for the surging.
Eventually found the problem (ECM) and had it replaced with an aftermarket part. The bike ran better after that but it never started as quickly as it did before.
If you do have a bike with the MM system, you need to find a tech that knows how to work on them, but that's true with about any type of technical equipment these days.
