Exhaust fume very smelly

[Crazy]

My exhaust fume very very smelly compare to other s4. Even using same petrol. What are the causes?

 

Too much carbon build inside?

[hst]

Too much onion ??

[ShnHwA-]

may b

 

-too much carbon

-incomplete combustion

 

[arjen]

your fuel to air ratio are most probably haywired

[TheBeng]

smelly means what bro?

can smell petrol?

[Crazy]

Dunno how to phrase it. Erm the smell very smelly(Not petrol smell)

Just wash n tune carb

Maybe too much carbon. But after i go long distance ride still have that smell lei.

first is ur engine oil is too hot it burn sum of eo..... second is carbon built in ur combustion chamber.... third spray sum perfume in ur pipe hehe

Morning start have the smell already. So think not because of EO Burn. Maybe is the Carbon built up.

 

Perfume? Good idea...

think u service ur carb then c how. hope its not combusting of ur EO... do check EO level cos it will drop if EO is combusted... then piston ring most likely have to change.

he just serviced his carb..

Got 2 type of rings bro..Compression ring and oil control ring...its always the oil control ring thats "koyak"...

Yea just wash n tune it. But nv check EO Level. Think i change fresh EO also got that strong smell.

Dead rat? No way!! Or maybe the rat is looking for Carbon for its meal. LoL

 

What smell.. erm Like normal smell but is more stronger/smelly

(Hope u get what i mean)

Oil control ring? Dunno what is that. What is the function Btw? Costly?

[JbAtRaCeR]

The purpose of the oil control ring is to allow the EO to lubricate the cylinder walls when the pistion move up(BDC to TDC) and scrape the EO back when the piston move down(TDC to BDC) so if the rings "koyak" its allows the EO to remain in the combustion chamber. The other way to know if your engine is eating up EO is by reading the plugs.

 

To change the rings?..Its like overhauling the engine..Very expensive..

Oh thanks alot. Hope that is not this problem..

mayb i missed the serviced carb part...

how many piston rings the piston shd have actually varies from engine models. but the rings' basic function is to seal the EO from combustion chambers so that they dun mix. if EO manage to make its way up to the combustion chambers, then both the ring have to change.

 

change the rings? good, after that, its like a new bike already...

[skateboy]

Oh thanks alot. Hope that is not this problem..

 

bro, did u try to blow ur bike, c if there is any foreign object in the exhaust that cause this foul smell?

[Nouvo_zimmx]

like wat dildo inside the exhaust pipe hehe.... sori juz joking usually for 4 stroke bike they have 3 ring for a piston.... which u all know that super 4 have 4 piston... might be num 1 or 2 or 3 or 4 piston of ur piston ring koyak..... try putting sum 2t like 20ml into ur tank it will cause no harm n if u see that a lot of white smoke means that ur rings have the chance for u to change its

How to check the EO level? No dip stick. Or make the bike straight on the bottom right the clear part where there is 2 marking??

[Epredator]

Long distance riding does not mean carbon will not built up. U have to wacked yr bike by dragging it.

Drag ah. Then think dun have liao... 10k 11k Rpm for awhile only.

could be a headgasket problem,does it smell of eggs etc, check your coolant to see if it is milky in colour and then see if there is any water in your oil

[moccajava]

exhaust smell sticks to your clothes smell?

Egg? Nope. Coolant Haven check.

Yes stick onto cloth. Thinks is normal right?

[putton]

Too much onion ??

 

:lol:

[Seiki83]

hmm... interesting... mine too, my exhaust smell also gave me a very strong patrol "taste" recently. Think last time forget to top up coolent, so could be my engine oil got eaten up a bit. My S4 just did a top overhaul 4 months ago and service my carb at K&T less than 1 month ago, so dun tink got anyting to do with my piston ring. Crazy, do you top up your coolent regularly too?

 

What you guys think??
