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.
What kind of lifter does a twin cam engine use?
The twin cam engine uses hydraulic lifters, which are able to compensate for heat expansion and normal valvetrain wear.
Why does my Harley Davidson make a knocking noise?
Twin cam engine cutaway. The crankshaft flywheels in the twin cam engine are pressed together and have the potential to twist or slip, which will cause a knocking noise in the bottom end or near the gear case; plus, a much more noticeable engine vibration.
Is it safe to drive a Harley with a twin cam engine?
The problems occurred in only a small percentage of the bikes, and the company quickly identified and corrected the issue. Still, if your twin cam engine is noisy and you drive a Harley with this engine style, check your cam bearings just to be safe.

Why does my Harley Davidson make a ticking noise?
If you are hearing an engine noise, chances are it is emanating from the valvetrain. If your are hearing an abnormal clattering or ticking noise, chances are it is a lifter. The twin cam engine uses hydraulic lifters, which are able to compensate for heat expansion and normal valvetrain wear.
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.
Are there any problems with the Harley Davidson twin cam engine?
There are plenty of defects in the Twin Cam engines. Enough potential issues to actually alarm you and make you think twice before buying one. The main problem of the Twin Cam engine of the Harley Davidson is probably it’s the design aspect of the cam chain system. The actual design itself is designed poorly.
What was the problem with the Twin Cams?
The problem that haunted most of these early twin cam models was the fact that the chains were made with sharp ridges on the outer plates that quickly ate away at the plastic tensioner. being spring loaded, there was always constant pressure on that chain, unlike newer models where the tensioners fill with oil.
What can I do about my Harley Davidson twin cam engine?
Harley Cooling is an effective way to help your twin cam engine. The oil cooler features a controlled fan that provides a continuous flow of cooling air, thus helping your engines cool down and reduce the wearing of the plastic shoes.
How many camshafts does a twin cam engine have?
A twin cam engine has two camshafts — usually double overhead cams. The camshaft is the part of a car or motorcycle engine that operates the inlet and exhaust valves. A vehicle with a twin cam engine has one camshaft controlling the engine’s inlet valve and a separate one operating the exhaust valve.
What causes a knocking noise at the bottom of the engine?
Bottom-End (Crankshaft) Noise. The crankshaft flywheels in the twin cam engine are pressed together and have the potential to twist or slip, which will cause a knocking noise in the bottom end or near the gear case; plus, a much more noticeable engine vibration.

Why does my new motor make a ticking noise?
Even Replacement motors have been bad for early Piston slap and lack of compression early-on for using THE one size fits all for their application.. If you want it to sound Tight and Not rattle right away (slap),, it needs to be torque bored Right an Tight to the specks given for the piston to fit their bore.
What kind of noises do car engines make?
Here are the 5 most common engine noises made by the engines and their potential causes: 1. Engine knocking sounds This sound is usually heard as you drive your car, changing gears and accelerating. The sound seems like something inside the engine is knocking hard on it.
Why does my Harley Davidson engine make so much noise?
Air-cooled engines lack water-jackets for cooling, so many noises that would traditionally be muffled are more audible. Additionally, most modern bikes use overhead camshaft setups, which are by design quieter than a pushrod valvetrain.
Why does my lifter make noise at high RPM?
Check the oil level. If the oil level is low enough, the oil pump may begin to suck in air at high RPM, thus starving the lifters of the required pressure.
What kind of engine noise does a Harley Davidson make?
A quality oil suited to the environmental conditions in which your bike is operated can greatly reduce the characteristic ticks and clatters. Many individuals will experience some form of piston slap in their Harley engines. This noise will often have a low-pitched metal to metal tapping sound as the piston rocks back and forth in the cylinder.
What should I do if my engine is making a loud noise?
The Fix: Replace air conditioning compressor. (This is not a DIY job.) The Symptom: A loud exhaust noise that may be coming from the front or the rear of the vehicle. Possible Cause: Worn out muffler or exhaust pipe. The Fix: Replace muffler and/or pipes as required.
