117 needs connecting rod bearing at 6K?

[PYLOO]

Hey ya'll. I got a 08 Mastiff with EFI with 6K. I picked it up used and only put 800 miles on it. It started to make a top end ticking noise. Sounds exactly like a exhaust leak. I changed both exhaust gasket. Then I did a pushrod adjustment. In the end. Nothing worked. So away to the Vet it goes. I took it to Sussex Hill Cycle in New Jersey. They did a compression test, leak down test, and checked the lifters. Everything came back good. He said it could be the connecting rod bearing and didn't wanna go any further without checking with me. He said it could cost 4K. Work will be slowing down soon so I told him to put it back together. I love this dog, but can't even ride it because it keeps breaking down. Did anyone have bottom end problems with such low mileage?

Seems odd that a rod bearing going out would make a ticking noise. Does the sound change as you Rev the motor?

 

[PYLOO]

No. The sound doesn't change. It does tick faster. If you are coasting down a hill and out of the throttle the noise goes away. I just have a hard time believing connecting rod bearings at 6k

Sven,

That´s yours... you will explain it better than me. (My Englisg is fuckeh toay) :up:

Yeah.. right! then, what SHE needs is a good break-in... don´t push her too hard... she might cry & bleed.... she´s a Virgin!!!




Fuck... My apologies.......... just re-readid (old training... check check double check) lol 8K on her.... (I said it... having a very bad day...)

Plese accept my apologies........ Welcome to this great Forum. Hurrraaa!!

I am going to disappear now...........

thank you all-

Ready?
1. I have this ticking noise, let me change the ex. gaskets = No joy.
2. I'm going to set the pushrid of that noise and oopseas = No joy.
3. I have cleared any tick-tick-slap-slap, what changes direction on the up and then down stroke? = Piston skirt Slap.
4. I have to look at my plugs and see a gray kind of plug, peppered spots of gray dots melted on the porcelain nose.
5. I want to smell the oil and if it's gas/sweet, I wanna beat my meat. If I smell something like burnt aluminum/metallic = Oh shit!

Fuck it it was 6ks........ Mamma.. Im going home..........

If you are coasting down a hill and out of the throttle the noise goes away.

Ready?
1. I speed up, I tick up under pressure bang.
2. I lift, I create a suck, a vacuum on lift.
3. I'm thinking small end bearing rocking the piston.
4. I think a rod would still bang, still fire, still knock the big end bearing.
5. I am going to pull a plug; set it in gear; move it forward just a hair or two.
6. I pushed bottom end bearing; top end bearing; big pin; wrist pin; at a load.
7. I want to pull the big pin back a hair, not two; I want to rod to drop too.
8. I now push the piston down and that tells me the crank connections have a clearance problem = Knock

Ready?
A. Top end noise = I eliminate an ex. seal, a cam tapping too tight on a lifter, I get a tick-tick and at the top end is the noise side to side.

B. Bottom end noise = I have a clearance problem up and down and that is a vertical knock, not a side to side tick.

C. Knock-Knock. Who's there? Franco. Franco who? Who's club do you think?

Ok. I think I'm following Sven. Lol. Knocking noise is the bottom end and a ticking noise is the top end. So I think you are saying the pushrods aren't adjusted rite?

 

[Sven]

So I think you are saying the pushrods aren't adjusted rite?

No, I said you did them correctly. Or, you would have said, "oh, the noise is worse now.' Or, 'I can't start the bike,' being 180° out of sequence.

That's how I figured out why for this example. When I set the valves, knew I could not be 180 out, nor have a too tight valve knowing 'tight ticks;' I tore the top end down. Cam was not wiped, or I'd have more clearance at the lash.

That made me remove the head. I then noticed the cylinder wall and the classic aluminum transfer to the barrels. So tight a seal, the leak throws a false reading snaking thru that transfer.

And that is all I can go by is you mention a tick, tackled both gasket and lash and you were nailing each one as I was working that tick thru. So, that's how I concluded you made all the right diagnosing and now you know a tick from a knock...

.... Only your cylinder to piston skirt transfer knows for sure. You did all you could do outside, time for the inside is my best Franco.

 

[woodbutcher]

check the vent tube in the gas filler neck to see if it is loose. sometimes they break.

 

[BadDawg Bill]

Wow, you need to find out where the noise is coming from. That can be hard. My brother in law had a noise we thought was a gasket leak and spent days trying to figure out where the noise was coming from. We tore down the heads, and everything else we could find. Turns out it was a bad lifter.

I find it hard to believe with that low miles it would be a crankcase bearing. Hell, I put over 200k on my last S&S without touching the bottom end.

It could be many things from a lose motor mount to the primary and everything in between. I'd find a good Harley mechanic who's been around and have him check it out. Like sven said check the plugs for grey matter that will tell you if it's a piston related problem.
Good luck.

My front rod bearing was wiped out at 18K on my 107"

Rod iz a knock not a tick, tick is rockers or lifters. Put a long screw driver high and low to your ear you will hear it louder at the point of the issue.

I think that your problem is in the primary since it goes away going downhill and throttled off, The motor is too new for the problem to be there.
I would adjust the primary chain to specs and replace the oil as well.
It might be your chain slapping against the cover making that ticking noise.

Worth a check in my opinion.

And yes BB is right with the screwdriver!

Old skool but works, I actually have a stethoscope rod for that.. Used a screw driver for years....

TICK TICK TICK TICK..........

 

[PYLOO]

Thanks for all the other suggestions. I will try them all!!!!! I will let ya'll know what I find. Feel free to let them keep coming.

 

[PYLOO]

If all else fails, it will be going to NY.
