It could be anything. The fact that the noise sounds louder when you let off on the throttle is probably because the engine is quieter then. Without being there where I could hear the noise, I'd say that you probably lost a roller tappet. More precisely, the roller bearing on the end of the tappet. These commonly fail between 25000 and 35000 miles although I've seen the fail as early as 13000 miles and run as long as 75000 miles. So, there is no set life on them.

If you continue to run the engine, you will do even more damage to it due to the influx of metallic shavings. The roller bearing on the end to the tappet looses is needle bearings. When this happens, the roller stops turning and starts wearing the lobe off of the camshaft it's running on. The metal is pumped to the oil filter that catches a lot of it but still some gets through.

I'm afraid that the only way to find the source of the problem is "exploratory surgery" until you find it.

Good Luck

    Did you adjust the lifters the correct way? The tappets have about 0.200" travel in them. You want to compress them approximately half this distance. So, you turn the pushrod down until they barely touch the top of the lifter and then turn the adjsuter down about 0.100" . Usually the manufacturer tells you how many flats to go down. It doesn't have to be perfect but the closer the better.

    Ok Next place that I would go is to the primary and check the primary chain adjustement. Always set the primary chain tension with the engine cold, just like with tappets and pushrods. You want to have 5/8" to 7/8" up and down play in the top run of the chain when cold. I'd pull the outer primary cover off to set this measurement. That' way, you can check the clutch, the chain, the primary compensator sprocket and all.

    If you don't find it there, you'll just have to keep on going until you find it.

    Good Luck

CODE 112 ON A 99 ROAD KING (CARBURATED)


Clatter sounds usally indicate a mechanical problem (or low fluid levels), not failing sensors ...

But error code 112 is failing cruise control: either the idle cable or the throttle roll off switch; it's pretty common.

2005 Road King oil light came on this morning when I started it. I turned it off, garaged it and went to work in my truck. Gonna go trouble shoot tonight. its only got 6,400 miles on it. what might it be?


I've heard the Twin Cam oil sensor located in the front of the cam chest is prone to giving problems. Start the engine and listen. If the engine sounds normal, check to see if you can determine oil flow back to the oil tank. I'm pretty sure the Road King oil tank is on the bottom of the transmission which is going to make this difficult. But, the fact still remains, if you do not have any oil pressure, your tappets will clatter like hell. It will be obvious that you don't have oil pressure. Check the wire to the sensor on the front of the "nosecone".

Good Luck

Your transmission has a straight cut 5th gear and not a helical cut 5th gear.

The engine knocks at higher rpm, only at high rpms


First no matter what check the oil level and then if it's a high rev tapping you need to allow the oil to flow through the engine block to try to coat and settle your valves.

But if it's really " knocking " sounds like your lifters and rocker arms are allowing your piston rods to clatter and that needs to be looked into fast.
