got tick tick sound from engine area..

[Baphomet]

my bike got this tick tick tick tick sound at the engine area..when throttle up tickling sound goes faster...this not caused by header crack or got hole cause just change header...the sound come from engine..... any bros can advice me? thanks~

[biting_point]

most likely your timing chain gone already.. need a top overhaul..

 

get a mechanic to check better..

[dragonforce]

ouch.. how much does replacing the timing chain cost? had a scare last week also.. occasionally hearing tick tick sound.. after realised its only my hp strap hitting the tank..

[s4vtec]

...just change header...

 

jus changed headers?

most probably a leak of exhaust fumes at the gaskets area...

did u replace the 4 gaskets for the headers?

[JbAtRaCeR]

The ticking sound made when the cam is pushing the valve tip to open the valve. If your mileage is more that 120k then adviseable to do top service. Best to get it checked coz you might only be needing valve clearance adjustment only.

 

If you want to detect air leaks between the header and exhaust port,try get a piece of paper, hold it near the exhaust port.

i experience this problem. but after warming up its gone. been sometime already but still dunno wats the problem. but my mileage only around 11k.

[rezasmess]

The sound is the result of the timing chain not set properly or have become loose. Jus proceed to a shop and ask them to check. SHould not be a mojor problem.

clutch housing worn out... but its ok... my spec 1 140k mileage. changed a 2nd hand clutch housing but the sound still there.

 

when clutch in, totally no sound, no vibration. but release clutch in neutral the sound and vibration do get irritating. but generally no prob one.

In my opinion bro the sound is made when you main gear shaft in the gearbox is spinning. When you clutch in,the sound is gone as power from the engine is not transmitted to the main gear shaft.

 

(This does'nt apply to all bikes.)

[lost_soul]

true.. recently i also realise that my bike vibrates while in neutral, but when i clutch in, the vibration is gone.

 

isn't putting the gear in neutral same as clutching in?

Nope..when you bike is at neutral the maingear shaft is still spinning. Its just the the selector forks are not in any gear position.

Interesting exchange, wat is header before I can really understand this matter.

 

Cam pushing the value tip to open the value - is opening of value good or no good...

Hmm.. I tot the tick tick sound is common? I heard every s4 also got the tick tick sound, but some loud some soft.. I ask mechanic they say no point changing unless it gives u problem.. He say s4 most will have this problem, so change liao very soon the sound will come again..

[Baphomet]

thanks guys for the advices...tok to my mechanic...he say no need change anything...he say normal leh. only thing is its irritaing...haiz... onli when warming up have this sound..after that no more...

[steel_headz]

Sound gone because once the engine is fully warmed up,the gap between the cam and valve cap gets lesser due heat expansion.

cam and valve cap gets lesser:? Is this normal for all "season S4". Why does Cam and valve got wider in the first place.

Its norm for all engines(overhead cam or overhead valve),the cam and valve cap or tappet wears out abit to fricition. So,to keep the gap to specification,they install in shims.

 

(This does'nt apply to hydraulic lifters on some engines.)

Any idea the cost for Valve Clearance Adjustment and yr recommendation pls. Thanks
