Hey everyone. I'm in need of some help again. I have a 2001 Heritage with a Screamin Eagle 120R engine. Last season I had a knocking noise in the engine only when it was warmed up and it seemed to be coming from the front cylinder, so I took it to one of my local shops and they told me to replace the lifters and to put adjustable push rods in and run a straight 50 weight oil. So I did and the noise went away. This year I went to go for a ride on Christmas and the knocking noise came back. Once again the engine was warm. So I'm hoping someone can point me in the right direction because I cant keep throwing money at this bike.

 

Without a video with audio of the engine running it's difficult to even start too tell you where to start. There's several reasons those 120's didn't carry a warranty from the factory.

 

A knock is one thing. A lifter clatter is another. when you replaced the lifters the first time what brand did you use? Like oldenough said.

 

I put S&S Lifters and S&S Quickie Push Rods

 

I'll se if I can upload the video that I have on my phone

 

I suspect that they treated the symptom and not the cause, so it came back. (And running straight 50 wt oil in New York is just nuts.)

Noise from front cylinder, low or high, left or right? At what revs is it most apparent?

 

I sound bite would be great. how many miles ago did you put in the new lifters and pushrods? Also what did you set the lifter preload to? Also when cold starting, how long do you let it warm up? What is the current mileage..?

 

The motor has only 2900 miles on it and I replaced the lifters around 2200 miles. I did four full turns on the push rods after I took out the play

 

50W is fine in the summer here.
20W50 spring and fall riding.
Any other noise(S)?

What did you use for lifters?
