At what mileage should I start thinking about changing lifters in 2018 M8?
What mileage do you have now and are they the stock lifters that came in it? Any noises or anything? If you have mileage around 30k you should probably have a look at them.
Stock cam/lifters? Should be good for the duration. If you change cam, then change lifters and inner cam bearing.
The cam inner ina bearing is a weak point. HD lifters I would not trust either.
"HD lifters I would not trust either."
Pretty much what I said in the post that got deleted. Several guys from this area I know, who post in HTT had factory lifters take out their engines. The last 3 new Harley's I purchased, I changed out before the first oil change..

Why do you say the inner cam bearing is a weak point, is there some history of M8 inner cam bearings failing?

INA cam bearings have a long history of failing.
Always use koyo full roller

FYI.... Due to Torrington selling to Timken, who later sold the Torrington Bearing line to JTEKT Corporation of Japan, Torrington bearings are now marketed solely under the Koyo brand name.

Did not know that. The last ones I replaced on my TC we're stamped Torrington IIRC but that was 6 years ago.

Probably NOS f they said Torrington. According to the article, they have been sold under the Koyo brand name since 2013.
When I did my first cam upgrade in about 2017, I looked around trying to get the actual Torrington Bearings instead of the "replacement" Koyo brand bearings. That is when someone told me they are one in the same, that Torrington sold out, and they are all now called Koyo.
As far as quality is concerned, in 2009 when JTEKT Corporation of Japan bought out the Torrington Bearing line from Timken (who originally bought out Torrington in 2003), they bought the manufacturing plants and tech center along with 3,400 employees. So they could be the same quality as when they were Torrington...

INA cam bearings have a long history of failing.
In M8 engines?
"In M8 engines?"
Good question, that I don't have the answer for.
In my M8 a different cam at 1000 miles, so the bearing got changed before I gave it a chance, LOL.
As said the factory use ina . Fit Koyo
INA make very good bearings ......
it's just that HD use the INA Caged Needle Bearing that is NOT up to the task as found by the many that have had the INA Bearing let go ......
HD themselves fit a FULL COMPLIMENT Needle Bearing in the SE's and CVO Model bikes
so it make sense to change the bearing to a Timken/Torrington/Koyo Full Compliment sooner than later
if you don't have/use a Bearing Supplier then Full Compliment Timken/Torrington/Koyo can be purchased from your HD Dealer at competitive prices to a Bearing Shop

I was not aware of this, but I recall when I replaced the cam bearings in my 09 CVO Fatbob the oem bearings were 9215 full complement bearings .
I checked Ronnies parts finder and looked at a couple of years/models and I note the 2017 Softail Slim has the 9215 bearings and the Slim S has 24018-10, but both full complement, different manufacturers ?
Ronnie's could be sourcing them in bulk from other sources. Were they in HD OEM wrapping?

I did not buy from Ronnies, just using their parts references to get my head around this.
It looks like the 9215 bearings are not full complement.

Is that an admission that they have a better bearing for the CVO but continue to use an admittedly substandard version for all regular models? :nix:

Similar to the SE lefty bearing ?

When you pay a premium price on a CVO, you gotta have a little extra over the regular one :potstir: :chop: :scoot:

That's an admission that they use the wrong valve springs & need the better bearing.
I'm surprised they don't put better lifters in them too.

All decisions are economic.
