Default M8 Failure count?

How many M8 failures do we know about?

I'm aware of 4. A Street Glide with an engine case crack, and three water cooled models with oil pump failures. Are there other threads I'm not aware of?

Good question! Start a count here:

1) Spurrs - oil pump failure, water cooled.

Yes I'm aware of both of your failures. And member Ashnik had a cracked engine case on his Street Glide. I thought there was one more water cooled oil pump failure...

Hang in there gentlemen. I don't want to add to your anxiety, I simply wanted to get a grip on how many have been posted here.

Pop over to harleytechtalk.org and ghost their M8 forum you want an eye opener and the up side it's where all the serious motorheads are trading notes on upgrades and performance tips . Very educational but not near as fun as this place.

Yeah, now I remember. It was a guy with a 2017 CVO. Street Glide I think. He had just done his 1000 mile service, and installed the 117" kit. Oil pump failure right after he got it back.

These four bikes are all I'm aware of.

I don't think I counted him, unless he was the CVO guy. If he is not the CVO guy, that makes five.

I know of 5 bikes that do not post on forums as well, 3 oil cooled and 2 water cooled. One had oil leaking through the cylinder itself and HD shipped out a new cylinder for it, One oil leaked from the cylinder head and HD shipped out new head, lines and gaskets. 2 had oil pump failures and one had a oil leak and HD shipped a new engine.

Sounds like a lot of bikes, but out of how many sold. We will never know unless a service bulletin comes out (which would mean too many).
