I read a lot about lifters taking out motors on the 110 why is it that they don’t have any trouble with the smaller motors ? There’s not much difference between a 96 , a 103, so why so much lifter trouble with the 110s ?

They all have issues, less so on the 96 and 103's. There isn't any rhyme or reason as to why but the speculation from many is that the 110 head spring pressures are really high.
-
Seems to be the newer 110's with lifter problems. I have an 2009 Springer with a 110 and have not had any problems. I am looking at a 2015 Tourer with a 110 and my service guy said straight away that I should consider better lifters.

Interested to know how many km's has your engine done?

I did lifters in my 08 springer at 18k and I did them in my 09 Glide at 31k.

Because they have a less intense cam lobe plus lighter valves, springs and retainers. None of them have good lifters from the factory but that said they are not the root cause.

Did lifters in my 09 Glide 3 years ago at 30,000,replaced with S & S

lifter replacement at around 30000 will make your twin cam much more reliable for the next 30000 miles especially if ya rideitlikeyastoleit

springs & poor quality lifters.install a set of S&S lifters and a set of beehives,you`ll be fine.good time to look into some porting too

Do any of the engine builders on here use a brand of lifter they would trust for more then 20,000 miles? I just put new lifters in with my 117 build st 8500 miles. My 1st set of factory lifters got replaced under warranty at 5000 miles because they where knocking hard up start up and didn’t pump up for 5 to 10 minutes!

Johnson or S&S, there are others as well.

Like a lot on here I like S&S premiums and I love Feuling. Both are very good.

There are only a few manufacturers that make that lifter. Most companies just re-brand em.
-
Correct. Old HD "B" lifters, S&S, and Fueling all look like Delphi to me.
-
Not exactly sure why people are so reluctant to replace lifters as a routine preventive maintenance. Agree, if the design were better it shouldn't be needed, but the reality is what it is. Once you have adjustable pushrods, a set of lifters with gaskets costs well under $200 and takes under 2 hours to replace. Seems like a better option to me than a blown engine; ESP or not.
-
The lifters are not the root cause, but replacing them every 15k will fix the issue.

Took my '15 in for it's 30k service. Sure enough, one lifter was starting to go. Esp covers it and the oil change :2vrolijk_21:
