Eyup, never gonna try cornering above 120 km/h. Not on NS anyway.

So finally I've arrived at the conclusion that the oil deposit on spark plug thread is a common characteristic of the 200NS engine. Many people got back to me saying that they found the exact same observation as I did - oily left plug and clean right plug (now this is assuming that the mechanic did NOT apply oil on the thread to screw it in, in the first place).

Now even though this is not a worrying matter anymore, what could the reason for it be? Could it be one of the following?

Synthetic oil is overkill for this engine.

Or

It's something to do with the bike being placed on side stand and leaned to the left over a few hours so oil trickles down to the left from the head.

Or

The fact that 4 stroke IC engines normally consume a little engine oil and the NS engine consumes a little more.

Or

The burnt fumes that blow past the piston rings into the oil chamber during the combustion cycle get recycled through the PCV system, whereby the fumes along with a small quantity of vaporised oil at high temperatures get pumped back to the intake to be mixed with fresh charge. This vaporised oil might enter the combustion chamber again and might settle on the spark plugs. But why left plug only? Perhaps something to do with the way the flamefront propagates in the cylinder as a direct result of the firing order of the plugs. For example if the right plug fires a split millisecond before the others, the charge bursts into combustion, pushing everything away (including vaporised oil) from this plug and the momentum is good enough to make it deposit on the others. Oh did i ever mention? There was oil on the main plug too.

Or

Bad quality valve seals or guides? This cant be because the engine is a gem, a high revving reliable engine which was designed and tested to stay rock solid at 11k rpm. A flimsy engine wont survive saddlesores, 1000 km days and high altitude runs in a variety of temperatures.

Anyone else curious to find out the story inside their engine may open the plugs at home and see.

Motul one had done 12k kms and bajaj one was under 2k kms
Motul one had oil in plug (left and right)
Couldnt unscrew thr right plug of the newer ns, left one had no oi.
Definitely seems like the fs oil.

divyansh....

I saw oil on mine p200ns 2012 model and a friend of mine 2014 model dual tone also found oil we both using oem bajaj oil.
My take on this its a engine oil additive due to high compression engine the oil additive is burnt and vapourised then comes up from valve.

Its probably spilling out

Use a little anabond on the threads and tighten

also you can take a strip of electrical tape and wrap it around the resivoir thread just once and then tighten the cap, will be like a gasket, but try to see why the oil is spilling in the first place

divyansh....

Aye chief! Thats a good idea, will try applying the electrical tape tomorrow after washing the bike.
And yes, need to get to the root of the issue.

The oil is spilling on the chain cover and not any painted surface. But having said that, I need to make sure its not spilling on the rear suspension.

----consecutive posts auto-merged-----

Are you sure man that it's the fs oil which is the culprit, i mean any oil will leave deposit if it is burned in the engine, you are assuming that right plug fires earlier than left plug because of which the unburnt fuel is pushed toward the left plug or main plug hence it has got oil deposit, can't this procedure occur in a opposite way since left plug is the main plug (i think) so this plug fires first and because this plug has to start the ignition a lot of fuel and oil is burned by this plug first, hence it has got oil opposite and the opposite plugs haven't, plus in a healthy engine you just cannot have any blow by, blow by will heat up crankcase temp and with it the oil temprature also, plus your engine oil will get contaminated which will again be picked up by the engine during intake stroke because the engine is not air tight,oil will get burned in the ignition stroke, plug will again show signs of oil and this sequence will keep repeating itself.

Yea the firing order / ignition timing is an assumption. Also, blow by happens in every bike and any bike during the combustion stroke. You can never have a zero gap between rings and cylinder wall. If that were the case the piston wouldnt be able to reciprocate up and down. The burning molecules are small and forceful enough to push the piston down to generate torque and forceful enough to push thru the few microns gap between the wall and rings. This is evident when the engine is on and the oil filler knob on the clutch cover is open. You can literally feel the blown fumes coming out. These fumes contain unburnt petrol and cant be allowed directly outside due to environmental reasons. You'll have a loss of mileage too, with wastage of unburnt fuel. Thats why we have the pcv system. Its in all bikes and cars. Thats why everytime you open the air filter box you'll find a thin layer of oil everywhere inside.
[MENTION=62311]royal racer[/MENTION] ive never ever used engine oil additive. It cant be that for sure. Besides the oils that we use already have many additives. IMO extra additives are a marketing gimmick. I've never had engine trouble without it.

Re: Pulsar 200 NS Owners Review and Experiences

@Aditya N Bharadwaj even bajaj mechanic didnt have some convincing reply on that issue ..

LOL
Regarding additive in some bajaj ASS they use at every service without asking to customer. i know that its a way of increasing the bill amount. As you mention its not additive
so i am sure its a valve gasket problem.
bajaj oil is semi ..?? because its just MRP 370rs on bottle

I also checked my plugs for oil.. all plugs are clean..
I am running fs oil and pushing almost 14k mark.. plugs where opened for 1st time
Adjusted and cleaned plug points.. Throttle response as improved slighlty..
[MENTION=55394]Aditya N Bharadwaj[/MENTION] :
Brother is pcv system present on all bikes?
I checked for oil layer as you said before.. few pages back.. i found the oil and outlet on ns ..
Out of curiosity i checked for same in splendours air box it didnt have any such outlet nor oil depsoits!
So where is blow back gases are goin??

Other than that i was told by my trusted mech was that it has 2 different inlets for fuel into engine ones normal intake and other is to carry extra fuel when bike speeds above 60kmh..

Splendor's air box has another route to the engine to send in more air for combination

Mech was right

Hi guys... Need a lil help.. I m not sure about the working of the cooling fan... Its a new ride., just clocked 500kms.. The fan was working fine for few initial days but i noticed its not working for the last few days... Someone told me it wud only work on speeds more than 80 kmph.. However i still have a doubt.... Plz suggest

Good morning,
Congratulations on the ride,
Now brother,
The fan comes on only after a certain temperature,
If you are moving constantly say on open roads the fan will not likely come on, since your forward movement is already providing sufficient air flow over the radiator to cool things down,
Its in bumper to bumper traffic where you cant get that constant air flow and its more than likely your radiator fan will kick in.
Also, if you have completed your first service its possible your engine is producing lesser heat, engine produce more heat during runn in as the engine parts just start to mate in.
Also there is no speed limit as to when the fan will work, you can be standing in one place stuxk in a red light and the fan will kick in,

Hope this helps,
Ride safe

divyansh....

Thanx for the reply Div... Bro the only confusion is.. My frnd who purchased the bike almost at the same time.. The fan in his bike kicks in after 4-5 after starting... Therefore was a lil worried

The radiator fan is supposed to come on only when the bike crosses a certain temp.
If the fan stays on alWays its a radiator fan relay thats stuck up,
A member faced this shubham2003 I guess, check page 1396.
Now, if you want to check if the fan works, just ride in bumper to bumoer trafic at 12 afternoon

,
What oil are you using,
If you uave not gone for 1st service then go and get it check, it should be just fine.

divyansh....

Re: Pulsar 200 NS Owners Review and Experiences

Just short the relay and see if the fan starts. Or redline your engine for a very small amount of time.

Yes buddy PCV or Positive crankcase ventilation system is a method to remove unburnt gases from the engine, in this sytem burnt gases from the crankcase is recycled through a valve called PCV valve and then to the intake manifold where they are again burnt, although these gases are mostly not desirable as these gases are only air which can lean the mixture.
