if some part may left dry then there is possibilty of entering dust through this area...am I crct?....

No sponge use to stop the dust entering....then why we use oil??
simply to make the air more clean, not blocking the holes of sponge.

This is how my air filter looks like....see that air flow..
the air filter absorbs most of the air from that part (states as RED)
And
can u see the yellow mark? If that part may left dry a little bit than would u think the dust will enter? Does the dust have a brain??
No man, then why we use a sponge if oil can only stop the dust?

You are getting too much deep into this....take it easy man
Just make sure to give attention to that part where air enters mostly...
You just only need to create a bit layer of oil into sponge & not to dip into oil

You know when I open my air filter for cleaning I see only that part most most dirty black where the air enters, rest all were looks clean.

Now I hope u get the idea how to apply oil to the filter

LOL on that brain part/..

Do you think water also has brain ?
When it does not have brain why does water drips into our homes from tiniest cracks in roof or walls when it rains heavily ????
Why does engine require oil seals ??

Do you even know what is the size of dust particle and why we call it a particle ?

Ever wondered why leaking engine oil attracts debris ??

In a foam filter that is coated with oil, IT IS THE OIL which is the FILTER and the Foam is the support for the oil....Please read up on different types of filters and their functioning and capability...

Dan's Motorcycle "Air Cleaners"

You are correct . And you are right in being extra careful about it , it takes a very small amount of minute dust particles to ruin your engine immediately .

Thanks again to PSR'jee for pointing it out timely .

Thanks for bringing up the Oil Bath Air Filter topic..here are some images to show it's construction and operation of filtering the air..
Most old timers like me have seen this in older version of Fiat and Ambassador cars..

Yeah ! our ambassador std mark-IV had one like this .

Thanks...what i was doing, i was applying a oil like people apply sauce to the noodles squeezing the bottle and pressing it hard.
or like we apply oil to the hair from end to tip, an optimum way.

No mechanic in my city apply oil to the air filter, NO ONE...
Not even in the Service Center....
So i thought they know what they are doing, but still i was applying a oil but not as it should be, i haven't thought ever to google it at least
My bike is 9 years old & i've started applying oil just 3 yrs ago, driving from 5 yrs...
Previously, my bro was driving bike and was running without oil filtering as he make all the works done by mechanics. And u know how mechanics do
As i got the bike in my hand, i was too young to do things myself. I was completely new. So slowly i started learning & learned a lot & still learning...

Edit: Should I apply new one or a drain one from the vehicles do the job?

After all, No One Is Perfect. People learn from mistakes!

Today I bought Champion Power PRZ7HC
I wonder if its original....can someone please tell me?

Air filter is the part which neglected often and it is vital in keeping engine healthy...

Mechanics use petrol from our own bike to clean the filter which is a big NO NO..the filter will degenerate in time and there is a possibilty of catching fire in case of backfire,,,and for the oiling what they do is apply very little oil from their oil pump in large spots and they dont even ensure that the oil is spread evenly...From my experiences my yamaha fazer filter suffered a lot with this kind of treatment.. i had to buy new one due to foam falling apart..And when mchnics do as above that will create al lot of dry spots through which dust enters the engine and gets embedded in the engine and works as sandpaper..and will die quickly...here in this thread PINAKI jee explained very well about air filter maintenance and its a professional method..
If we over oil the filter bike will not rev,spark plug will be fouled,,we can see a brownish black color smeared with oil ,,mileage will decrease..
The most trickiest part is to remove excess oil ..
For my splendor 90 wt oil wrks and for my fazer 2t oil wrks good for air filter oiling

Friends
What is the procedure to clean spark plug.. and do we have to clean the spark plug hole .....then what solvent is used to clean the both?

Just remove the spark plug and wash it with thinner or carburetor cleaner and gently use a wire brush to clean it.

Gap the electrode correctly.

Clean the spark-plug washer mating surface with a clean cloth.

Lightly oil the spark-plug threads for easy installation.

OR Replace the spark-plug if it is fouled.(Rs.65/-)

It's not only you , mechanics used to do the same funny things on my bikes early in my riding life and consequently I suffered a lot , until I found out the correct way of doing things gradually . Nowadays I rarely visit them for service (and don't have to push my broken bike to their shop ever) and they are not happy about that too . You can read a simple guide I wrote on this sometime back on this thread , if it's of any help . Here is the link to that - http://www.xbhp.com/talkies/633221-post85.html
Also buy and keep a spare set of those two air-filter elements(85 bucks total) , so then you can replace dirty ones anytime in a few mins . Then you can do the cleaning and re-oiling later when you find leisure time and keep that ready again for next change . This method almost makes it too easy to do .
I already replied to your oil query on the engine-oils thread , please see .
Correct one ! I am using this same one right now , made by federal-mogul . I already donated the OE plug (ngk cr7-hsa) to my friend who rides a wind-125 .
Clean off carefully all around the plug hole BEFORE you unscrew it and after you take the plug out , plug the plug-hole with a clean cloth so that dust & foreign matter may not fall into the bore . I carefully scrape off the carbon with a razor blade(held at angle) and a metal wire for the deep groove, then polish the two electrodes just a bit with a bitsy of 1000grit sandpaper then spray any solvent on it (carb-cleaner/iso-propyl alcohol/paint-thinner etc) and wipe off . Then regap it to 0.7-0.8mm with feeler-gauge (recomended gap is 0.6-0.7mm) . Yes ,don't forget to scrape clean the threads on the plug and wipe clean the plug-hole threads on the bike, with solvent and repeatedly if necessary . Thats because the threads and the plug-hole is the electric-current's path to ground . While refitting the plug, screw it in by hand untill tight . Then with any plug-wrench tighten it 1/8 of a turn ONLY . For a new unused plug , tighten 1/4 th of a turn ONLY .
Don't try these on thin-electrode G-power or Iridium plugs . Those may only be gently wiped off with soft cloth wet in solvent . Those thin center electrodes are easy to deform or break off .

Tip 1 : A number 16 ring spanner (deep) fits the Splendor size plugs perfectly and makes it easy to take out and refit . But be soft and easy with it if you use it , it leverages a lot of force .
Tip 2 : Carb cleaner is the best cleaning solvent for this , the aerosol spray action helps too . And if you spray a burst of the carb-cleaner into the plug-hole (bore) just before refitting the plug , your bike shall start at first kick after refitting .

Very good explanation as always,Pinaki ji.
I don't think the spark-plug thread is the only electric current ground path because the big sealing washer is also grounded.

Any specific reason for spraying carb cleaner into the bore or just to help in easy starting of engine ?

The correct lube to use on spark-plug threads is anti-seize grease (copper-grease) which is also electrically conductive and which I never found here .. many use a drop of motor-oil .. I prefer to keep it clean and dry . If you use a light screwing force and take out and clean plugs regularly ... not much difference I guess . So grounding is not the sole logic .. I just like it this way
You must have noticed that after cleaning the plug , it takes a few more kicks than usual to start the engine , no ? Not much else , other than a faint hope that it may clear up some of the loose carbon particles in there a bit too .
