What makes the engine noise on a Harley Davidson?
Here’s a trick to reduce the constant engine noise that sounds like valve train noises on the newer 96 Cu In. bikes that have the auto adjusting primary chain tensioners and no inspection port. I tried this on my RKC and can notice a definite improvement.
Why is my engine making an odd noise?
It has a very unusual noise coming from the engine and has been making the noise for about four months without any real change. See the video for more details. Compression test showed no leak (183 front cyl, 185 rear cyl). Tore the top end apart and found no issues.
What happens if your twin cam engine makes noise?
This is perhaps the most costly failure on the twin cam engine, as it can basically trash all engine components, leaving you in need of an entire engine. Prompt action when you first notice the noise or vibration can prevent a catastrophic failure, but you are still looking at an costly bottom-end rebuild.
How to diagnose engine noise in a motorcycle?
The first step in diagnosing an engine noise is to narrow down which area the sound is coming from and under which conditions the noise occurs. A mechanic’s stethoscope is a great tool to use when diagnosing engine noises, as the probe can reach into tight places to monitor the sounds of the engine.

What kind of oil should I use to make my car make a noise?
Although it is likely not to be a really good solution, increasing the weight and viscosity of your motor oil may lessen the noise so that it isn’t annoying. Find a heavy duty 25W-60 motor oil, especially if you ride in high temperatures like in the southern states.
Why does my primary make a rattling noise?
They took the bike in, disassembled the primary and did not find anything wrong. After putting it back together, the noise was still there. They took it apart again, compensator, clutch, everything and called HD Tech Support with spring measurements and whatever other info the dealer provided.
Why is noise a problem in power supply design?
Noise is a constant problem in power-supply design. While there are FCC limits on the electromagnetic interference (EMI) radiating out into the air as well as the conducted noise that your design injects back into its input, your first noise problem is getting the noise low enough in your outputs.
Why is my primary chain making a noise?
Do this 2-3 times in succession and you’ll notice that the noise that you thought was the valve train is almost completely gone now. Low speed riding is a bit smoother also due to less play in the chain. By doing this, the automatic primary chain will ratchet up a bit tighter if it was loose before this.
What causes a howling noise in the rear of a car?
Cause:Worn rear pinion bearing or worn gear set Noise:Howl without whir or rumble while accelerating at any speed (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading Noise:Howling while accelerating over a small speed range (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading

Why do I have a hum coming from my speakers?
Modern signal cables are well shielded, but if you’re getting hum and it’s not a ground loop, this could well be the cause. Note that the cables running to self-powered speakers (non-Wi-Fi) are audio signal cables, not output cables.
Why does my transmission make a clunking sound?
Extremely bad bearing. Clunking Sound – A loud clunking sound when the transmission is in a particular gear, usually under acceleration (but can also show up under deceleration too), could be gear with broken or missing teeth on one or more gears.
What makes a transmission whine in a Harley Davidson?
The hardened steel spring can cause damage to the transmission gears if not recovered. Transmissions can offer an whole repertoire of strange sounds from a low growling or rumbling sound to a high pitched whine. We’ll describe some common sounds that that may be associated with a transmission problem.
What does it mean when your differential is making a noise?
While there is no help for our singing, we can help you diagnose the sounds coming from a differential gone bad. A clunk, whine, or howl can signal a worn-out pinion gear, bad bearings, or a faulty gear installation. Sometimes, the noise is not differential-related, but is caused by other driveline or axle components.

What causes a low pitch noise when accelerating?
Noise:Howling while accelerating over a small speed range (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading Noise:Howling after gear set installation Cause:Faulty gears or improper installation Noise:Low-pitch rumble at all speeds over 20 miles per hour Cause:Worn carrier bearings

What causes a loud grinding noise when making a turn?
Cause: Posi chatter due to improper lubrication; worn clutches or spider gears; improper assembly Noise:Banging, crunching, or popping while making a turn. Noise not affected by temperature Cause: Badly worn or broken spider gears Noise:Banging or heavy clicking every two to three feet during acceleration and deceleration
