Default Buying my first M8

Hi everyone,

I'm usually over in the Dyna section so I apologize if I'm asking something that's been covered.

I'm looking at getting my first touring bike, I'd like to get one with an M8 since I already have a Twin Cam. I'm looking at 2017 models because each year newer is more expensive, but I know there were first (and second) year M8 problems.

I'm looking at a bike with 2,600 miles, heck I do twice that in a year. My concern is, does this engine have enough miles on it to even know if there's a problem ? From what I've read, an oil pump redesign seems to be the main thing that resolved the sumping. Is there any way to know if this engine has a newer pump?

Aside from opening cam chest or service records, no way of knowing. That said, I have 15k (others have way more) on the 2019 oil pump (not the newest). It’s a stage 2 Harley Torque Cam and never had any sumping symptoms.

Can you buy an extended warranty, ride it, and once satisfied get a refund on what was not used? I have never had a warranty but I think you can do this?

Another option, take the money you are saving on a later year and buy the new H-D oil pump for ~$150 (I think less) and change it out. Do a stage 2 while at it.

Otherwise, I wouldn’t worry too much about it if the bike comes with some sort of limited warranty.

Are you keeping the Dyna? I traded in a 2011 Street Bob for my 2019 Street Glide and man do I miss it sometimes. Not enough to get rid of the touring model though.

Good luck and keep us posted.

Edit to add: Looks like you have the Royal Blue Low Rider. I love that color and bike. My son is 3 but I have my wife (and myself) convinced he will need a bike in a few years so we can start working on it. That exact bike is at the top of my list.

I am going to check on this, because it doesn't come with any coverage.

The 2020 pump is a recommended upgrade. The stock pumps scavenge oil in a 60/40 split, the new ones are 50/50. IMO HD should have retrofitted these for all the M8s. I'm kinda squeamish about going into the cam chest and swapping the pump. I don't mind doing maintenance and parts but going into the engine is beyond my comfort zone.

I really want to keep the Dyna. My plan is to ride them equally and not run up the miles on one bike too much. If I can't swing the finances, then I'll just try again next year. If I sell the Dyna I know I will regret it.

It's actually Superior Blue, and funny thing is the bike is a 2014, but they didn't make this color until 2016, so somebody did a tin swap. I'd love to know the story behind that but probably never will.

Personally, I’m not quite experienced enough to open up and work in the cam chest either. That said, you can do it for about $800-$1000 which I’m sure you will be saving from buying say a 2020.

There are more issues than the oil pump to be aware of. Watch some videos on YouTube from Kevin Baxter. Is this a private sale? I'm not trying to scare you only inform.

Kevin is a great. I got a chance to spend a day with him and he is the same guy in person as online. I am also his first paid subscriber to YouTube so yes I trust his opinion.

Never going to gain the experience if you dont try... Its all just nuts and bolts torqued to a certain spec. Manuals and youtube are your friend.

This is true. I am planning on getting another (used) bike in the next few years and will learn on that. Prefer to not blow up my 2019 Street Glide engine.

Fair enough I guess. Grenading a 4-5k bike is easier to take. I dont know your background. My softail is the first bike I cam swapped a few years ago going the 'removing the tank' route to reuse the pushrods. I thought it wasn't bad. Just follow along and take your time. Read the write ups, watch the vids, read the manual... But given what I've done wrenching, and the swap I've done, I'll be doing my street glide myself without worry once the warranty is up. You gain experience by trying, pushing yourself, asking for help when needed, and learning from others. And failing, but that's not a good method of learning to discuss here. Lol.
