Any solution to this problem

oil directly coming out of silencer,smoke coming out from exhaust,oil level dropping.

But

SPARK PLUG IS COMPLETELY DRY.NO OIL ON SPARK PLUG.

Is there any oil inside the air filter box ? check it ..

No
There are no traces of oil in air filter box.

One thing I have observed and that is
my bike's compression is too much
I mean to say that you need to kick start it really very hard.
I suspect that due to this high compression,Oil is going somewhere else but I am not able to trace it where it goes.But I can see too much oil directly on the exhaust tip.
Also I noticed that while starting in morning,if I keep my bike idling near to 1000-1500 rpm no smoke from exhaust
But after that if I slightly increase rpm by giving slight more throttle or raising the choke,huge smoke starts coming from exhaust(More than a 2 stroke vehicle or a diesel rickshaw)

Frankly , I have no idea how your engine oil would drop so much and end up in the exhaust (even in traces) without passing thru the block-piston-valves area or the air-path .

Does your silencer really drips oil? I mean, it can also be carbon or something.. Which is dripping after getting heated.. Just my thought!
and if your bike is running very lean then you wont be able to trace oil on spark plugs. Happened to me..

Yesterday while servicing the bike,the mechanic removed the air filter and when I touched the pipe which was connected with carb,I found it little bit oily from inside.
2-3 days back,I didnt observe too much.

So maybe the oil is entering into air filter

This time I changed my oil with 20W40 Castrol Activ 4T and this problem is minimized.My bike gives very less smoke and sometimes no smoke
Earlier I was using oil from TVS Tru4 available from TVS service which was of grade 10W30.
By changing engine oil to 20W40 there is some change

One more question to ask.
I can understand that if valve or block piston has a problem,oil enters into the cylinder,gets burnt and there are residues on spark plug in few kms of cleaning the plug.
But I am not able to understand that what can cause oil to come inside air filter(Because so far I know that intake and exhaust valves and piston rings or the block itself can give problems.But oil entering in air filter is new for me.I dont know ahat could be the possible cause for this to happen)
Any reasons for oil entering in air filter

If oil is like this,Its completely normal!

Thanks Aneesh

The oil which I found inside the air flter-carb pipe was little bit more that what is shown in the photo.
The inside metallic mesh of the air filter was smeared by oil but the outer sponge material was dry and few traces of oil on the air filter-carb connecting pipe.

I googled on "oil entering inside air filter" and found out that a Positive crankcase valve or PCV is responsible for this.
But I dont know where is this PCV located in bikes.Any idea about this?
So far I know,my bike have got two valves
1 for intake and another for exhaust
Also there is a crankcase breather outlet provided.
No idea of this PCV valve.

Secondly I am using Castrol 20W40 grade oil instead of 10W30 and my problem is minimized but still there.

If Crankcase breather tube is connecting crankcase to air box its called PVC valve..
And 10w30 (lighter) oil oxidises more than 20w40, that's why your problem reduced..
Is your bike overheating??

I checked my spark plug short while ago.
My bike is overheating
The spark plug tip is dry and whitish-light brown in color and mileage I get is around 65 kmpl on highway and around 60 in city.

But now I have problem only while starting bike in morning.
After that even if I ride for 100 to 200 kms,still no smoke
But when I kick start in morning,I have to kick it hard.
Due to which I think that oil might be coming to air filter through PCV valve
But if this PCV valve has problem then should I open the engine/crankcase?

The kind of oil inside Aneesh's air-box (photo) is from oil dripping off an oiled-foam type air-filter ... normal . Very over-oiled air-filter of this type can also make tha carb-air-intake manifold ( rubber pipe ) a bit oily inside ... but certainly not drops or puddles of oil there .
The air enrichment pipe/crankcase breather pipe will have valve somewhere , if engine oil is overfilled ( above max mark on dipstick ) or this valve is malfunctioning , oil / oil vapours from engine crankcase will pass into the air-filter area and condense there in a puddle . Have this valve checked by the service center .. . No , no need to open crankcase .. this kind of valves are usually outside somewhere .. it's plainly visible outside on my splendor for example .
Also your engine seems to be tuned over-lean , make it a bit richer mix . I already knew that your engine is overheating ... that is why the 20w40 seems to help .. but that is not the right way to solve the problem in the long run .

Aneesh , did you take this pic inside a oiled-foam type air-filter box ? Only these may have some oil from dripping off the foam element . Else it isn't normal to have any oil inside the air-box . Oil getting in there with a paper-type / cotton-gauze-type / viscous-paper-type air filter will destroy the filter element and prevent it from functioning . Paper element will be destroyed by getting wet with water too , even once .

No bro,Karizma uses Paper Filter.No matter how much oil is seen in the box,It never touches the filter element and will be completely dry.



According to psr.

hard kick is not the problem it can't throw oil in air box. Btw, its a sign of awesome compression.
The problem is PVC valve &/or engine overheating.
Get your PVC valve checked/replaced and tell your mechanic to tune for slight rich mix

Ok , psr have been doing quite in-depth research on the kari so he should be knowing better . I didn't know about this .. yes no problem as long as the paper element is not wet 'ed by the oil . Possibly this is why they left that wide flange margin around the element .

Yeah,me too think so.
