parking your bike after overnight

[dingjc]

hi guys, this is something i encounter.

 

after parking my bike overnight. when i start my bike, i will hear sounds from my engine. its not shim sounding ( not small noise like tiak tiak tiak).

 

its like drum beating inside the engine. khruk khruk khruk khruk. but after warming up for sometime, the sound gets lower and lower and eventually disappear.

 

im using ngk standard s4 spark plugs, maxima engine oil 15. its a FU spec1.

 

motordiam says its normal. and mechanics have told me it maybe my low idling (1rpm). which i dun think so. mechanic also says it may be the clutch housing (not clutch plate).

 

can anyone please advise and share with me please?

 

im riding all along a relax style and throttle easy wan.

A drum beating in your engine is a cause for concern. As melodramatic as it sounds, could you pinpoint exactly where it's coming from? Start your bike and squat beside your engine with a listening ear. Is it from the engine block itself? Gearbox?

Fake petrol? Then I would assume buying EO from JB would also turn out as a fake? No such thing bro..

if im not wrong, its from the engine block ! im kinda worry.

One of the funniest thing I heard.

Fake?? Unless you buy from roadside peddlers selling from used pepsi bottles, pump fuel from JB are definitely on par with SG's fuel. I presume you pump RON97 so even if the petrol is slightly contaminated, it should only be RON95-96 which is actually way too good for most bikes.

 

That's my personal opinion only though. Maybe there's more truth in your statement than what most of us interpreted.

[eement]

no la it normal ba

 

i oso have it after a while should be ok de

[dumbnut]

It's pinking.

[dingjc]

It's pinking.

 

wads pinking ??

There is no such thing as fake petrol but cheating on grade blending yes, that's the ron nubering. When you have this..go get a bottle of octane booster and follow the instruction what is there mising ratio.

 

As for the sound you describe correctly and from the engine block, its more like excessive cam chain (timing) balck lashing...about time to replace your cam chain tensional. Its that cone triangular like things with a size 8 hex bolt sticking out near the lower middle back of your engine block. Quite common for old bikes...unless your's is a new old. Cam chain is very lasting if this thing is taken care off.

 

Please..don't go back to the shop that the mech have told you this is normal. Should asked him how come all other S4 oso normal don't have. All I can thing is that they can't quite handle the job..may be change eo, spark plug and adjust chain can....LOL!..idiots!

WHAT IS PINKING?

Its pre-ignition , that is when the petrol/air mix in the cylinder ignites before top dead center , this creates the noise..oso known as "knocking".

 

Having the combustion occur when the cylinder is not in the correct position to deal with the small explosion (i.e. on its way back up) can knacker your cylinders, and all the gubbins that's attached to it. Don't f around with this..get it resolve.

 

Pinging or knocking noise sometimes heard during acceleration indicates detonation is occurring inside the engine . Spark knock can be caused by low octane fuel, over-advanced ignition timing, too much compression (often due to a buildup of carbon in the combustion chamber) or by too much heat. If switching to a higher octane fuel doesn't cure the problem, the cause should be investigated because prolonged or heavy knocking can damage the engine. Imagine its like taking a hammer and whacking it on your piston head direct and asked yourself how long that piston is gonna last..know play play.

Suggest you go around the advertiser here and talk to them the problems and asked them to "quality guaranteed" and "wont TOK you like carrot" lor

Must pinpoint where is sound is coming. You mention the engine but which part?. Cylinder head cover,cylinder block,clutch housing or etc?.

Bro, very likely its ur clutch basket..... Normal to hear that esp when in neutral or not in clutch..... should disappear when u clutch in.... Due to the amt of abuse the clutch is put thru in every day use..... BUT not normal if u still hear it after u engage gear or clutch in.......

[kitty23]

clutch basket is a lil seasoned. No performance issues for this.

 

Time to get your carb serviced.
