Lifter Gone Bad? (120")

[Eglider05]

So I'm out for a ride today, picture perfect weather, bike running great and then it happened. I pulled off the side of the road briefly so my wife could retrieve something from the tour pac. I didn't shut the motor down, just let it idle. When I accelerated to get back on the road I start hearing the noise in the video. Oil pressure is good, bike doesn't seem down on power. It's up and down with the rpm's, worse at idle and pretty much disappears as the revs climb. Could this be a lifter gone bad?(I hope) What should be the first order of business, pull the lifters?

Thanks,
Rick

Sounds like cam bearing or lifter roller. I would definitely take it apart, and not run it anymore.

I'm hoping it's a lifter. I've had some intermittent lifter noise but didn't think too much about it. There was nothing out of the ordinary when it happened, pulled off, stopped for maybe a minute and a half and throttle up and there it is. Up to this point this thing has been trouble free.

I hear the knock, but also sounds like a squeal too. Could just be the recorded sound, sometimes not the same as being there.

I heard the squeal too, my wife says no. I popped the clips off the pushrods and I can slightly move the rear intake pr. The others are tight.

Sounds like a lifter roller quit rolling. Hope you stopped it before it damaged the cams.

[joe_lyons]

Does the sound follow the engine load or just rpm?  Example of this is if on decell and idle you hear the noise but on throttle it goes away.

Me too, I should know later tomorrow.

Didn't go far after this happened. I don't recall if it did it on decell but is definitely worse at idle. On throttle is does seem to go away.

You can bank on that, I'll be back asking for advice on this one I'm sure. I hope to get into it later today. I can't wait too long as it's driving me crazy. Regardless of what this turns out to be I going to throw in a set of the S&S premium lifters with limiters in.

Almost sounds more like a valve not closing to me...   

[Eglider05]

It's the front exhaust lifter. It still turns pretty freely. I assume I have to go deeper?

Thanks,
Rick



Flat spot.

So do you still like gatermans?

I sure would.

Sorry to see that, but better to find it this way, than after it exploded.

Not so much anymore.

I'm thinking there's about 16k on the motor. So what should my next move be?

[No Cents]

pull the cam plate and cams and take a good look at the cams, and the cam plate, the oil pump, and cam bearings.

added later:
I too am sorry to see this happen to you.
Did you say the roller on the lifter still spins freely...it looks like the roller bearings are a mess?

[Admiral Akbar]

Pull the cam chest..

Thanks for the replies, I figured as much.  I don't want to do more than necessary but I also don't want to shortcut it. Had to check my records,, it looks like closer to18-20k on the motor.

Thanks,
Rick

Hi Don,

If I pull the high ratio  rockers what cams will bolt  in without a lot of fuss. I need to get this back on the road.

Thanks,

ok so root cause here? sitting on the side stand idling, come on?  With cams and the like is this stuff like a race engine and cant idle below 1800 rpm?

Wasn't on the side stand, not that it would matter. Just a lifter failure.
