bike engine sound problems types reasons

Here are some common engine sound problems and their possible causes:

Knocking sound from crank soft bearing problem

A solid knocking sound that comes from deep in the engine could indicate a serious problem, such as a worn-out or loose rod bearing, or a collapsed bearing. This could lead to the engine seizing while riding.

It increase while you Increase RPM Crank Bearing sound or  piston Pin.  low engine oil crabk bearing wornout fast.

Popping sound

This sound could be caused by gas leakage, which can lead to fuel wastage and accidents. It could also be caused by clogged fuel filters, faulty ignition components, or damaged catalytic converters.

 

Clattering / rattling sound timing chain tensioner

If timing chain skipped 2-3 more teetch then piston and valves hit together and engine seize.

Affect the timing of the valves and piston.

This sound could be caused by a failing tensioner, age-related wear and tear, or a timing degenerating chain.

rattling noise at idle and lower speeds.  (engine rattles while idling)

Engine misfire: skipping gear teetch due to lose timing chain volves and piston not synchroize properly

Poor engine peformance: timng chain loose disrupts the engine volves timpley open poor performance.

hazard indicator: ECU may detect Timng of the engine crank shaft to camsahft by timing chain.

causes: low engine oil, poor maitance of engine oil. wearout

timing chain hydralic then it occurs in cold start and goes way.

Timing chain skipped a tooth how to identify?

Other signs of a bad timing chain include: Decreased power and acceleration, Increased exhaust emissions, Engine overheating, and Unusual engine noises.

If your timing chain skips a tooth, you should have your checked out immediately because the chain could break at any time and damage the engine

Rough running: The engine might misfire, idle poorly, or run roughly.

Check engine light: The check engine light will come on.

Metal shavings in oil: A damaged timing chain can break off metal parts that mix with the oil. You can check for this during routine oil changes.

Visible chain: You might be able to see pieces of the chain.

Difficulty starting: If the timing chain breaks, you might have trouble starting the engine.

• Crank soft & cam shaft ratio  2:1 (only one time volves open),
• not picking spped & accelaration due to poor combustion (slightly mismatch volvs & piston).
• Metal Particles engine oil drain 
• Check engine light hazard
• Not starting if breaks toally

Whining sound gearbox

When your press the cluth sound goes off.

This sound could be caused by a gearbox that is failing or performing poorly.

Ticking sound at engine head Tappet Noise volve clearence

This sound could be caused by a number of problems, including low oil, engine issues, or valve train hitches. Ticking that increases when the revs do could be caused by loose valves.

Grinding sounds from brake pads

 

This sound could be caused by brake pads that need to be replaced, or a caliper that is causing the brake pad to drag.

Loud engine sounds
This could be caused by an issue with the exhaust system, which manages the gases from the combustion cycle and muffles the engine noise.
