K&N Air Filter Queries and Doubts

[Midhun.akd]

@samarth & others ..sorry for inaccurae interpretation.. i'm very weak in englsh..sorry..

Somewhat Inaccurate interpretation of information.

I have myself held both main jets (117.5 from Pulsar and 125 from Karizma) in my hands, and the Karizma's hole was clearly bigger. This was when I installed RC1060 on my Pulsar. I have also used Achiever's main jet (#118) which is again for a Keihin carburetor and that too was minutely bigger than 117.5 from my Pulsar. This was when I was getting Joel's kit installed.

My assumption is that now jet sizes are standardised and Hero Honda measures their jet sizes in Mikuni standards. Or maybe the standards are for the international versions of these carburetors... or something similar.

So as u suggest karizma one is better instead of choosing rtr's one..!!

Or can it be easily get from the hero Honda agency or have to buy online from somewhere...

@samarth619
Bro is it better to remove the stock exhaust nd installed exhaust pipes directly from the gasket till the end while giving bend underthe seat of better to install a small exhaust between it... As I want to give a Ducati look to exhausts.. Plzzz suggest..!!

As per jetsrus site.. Karizma's Keihin 125 main jet is actually smaller than mikuni 117.5 jet.. When it compare keihin 125=mikuni 110... Just check it out guys.. Jets R Us mikuni, keihin, hitachi, holley, jets and carb parts Rtr180's mikuni 125 main jet is the best suit for 117.5 mikuni..

@ Sangam Arora: Buddy, I can confirm that Karizma's main jet (#125) costing Rs. 153 fits your bike, because it did fit mine too.
I haven't held or fit RTR's jet yet. Theoritically, it should be the appropriate size and fit well too.

@sangamarora..pulsar& all other bajaj bikes carbs are mikuni.. If your mainjet is 117.5 then rtr180's 125 mikuni mainjet is ideal choice..

In my humble opinion it wont increase milage of the bike sure you would get better sound but it comes with the power lag at times i had one i told fzs power output remains the same,company filter is way more better.:thumbup:

Using it...! Utter useless filter...!
Rather install a Conical Filter ! & Upjett...!
Mileage should stand sumwher aroun 35-36 Kmpl..

Hello
I am planning to replace my stock filter with a K&N filter for my fz 16. Is K&N YA-1611 the right one. I checked out K&N official and it says the filter leads to increase horsepower and acceleration while providing excellent filtration.I have even come across people who seem to get better mileage after installing them. Does this upgrade really help? I really need some advice before going for it as i don't want to cause any harm to the vehicle. I would also love to know the advantages and disadvantages of this product on my bike.

Your bike must be running lean. Like I told you before, get a Karizma jet #125 because no other jet comes between 120-122. Do these things:

1. Firstly, protect the filter from dust/ rain. Use a compatible Air box from the market which fits your bike. OR Try wrapping it with some kind of cloth or something atleast.

2. Warm it up by riding 1-2 kms, start the bike in neutral and put it on main stand. Don't touch the accelerator. Let it run started on "idle rpm". Does the tacho needle move up and down, in an unstable manner? If yes, then you should rejet. Get a bigger jet for your bike, like the Karizma's main jet.

3. Turn the fuel knob to "Off". When its off, see the below diagram and open these 2 screws to see the main jet. You will see the main jet. Just rotate & unscrew it carefully and replace the jet. Rejetting is done.

4. After re-jetting, you need to fine tune the AFR... Locate the "AFR screw" on your bike. Keep it on full tight position (right side= tight I think).

5. Now, turn the fuel screw to "on/reserve". Start the bike, the rpm needle should move up and down like earlier.... Increase the idle rpm through twisting the idle rpm screw with your hand... Make the Idle rpm around 2.5 krpm for now...

6. Keep the bike started. The rpm needle will move up and down in unstable manner, like earlier. Slowly, make the AFR screw looser and looser, until the rpm needle is stable. Then, when rpm is stable, reduce the rpm to around 1400 using the idle rpm screw again.

That's it. Your bike is tuned....! Now, you can ride it hard, but remember, do not leave the K&N open... It will attract dust and kill your engine in 1-2 years. Then, it would be more expense.
Keep the K&N filter clean, according to company instructions. Don't get it cleaned at Service Centre's air pump, as it will damage the filter.

Use the below diagram to understand the above underlined terms:

Which size jets are used for rejetting...for pulsar 150cc crab... ??
Plzzz guys help me out plzzz

Depends upon its year and model. It maybe 112.5, 115 or 117.5.
And the new jet size? That depends too upon what kind of filter you're installing... For RC 1060, it has to be bigger by 7.5 points approximately.

I have a Pulsar 180 UG3, on which I did install K&N RC 1060 once. I used a 125 jet from Karizma instead of 117.5. And it went very well, I used to love its roar.
But you or your mechanic must know how to tune the Air Fuel Ratio. That is a must.

I just had installed k&n filter(rc-1060) in my pulsar 150cc ug3.. But I m confused with it... Just want to knw... There is pipe that coming from the engine nd attached to stock filler is remain open now after removing of stock filter... So just want to knw... ??? Wht have to be done to that inlet pipe if air for engine...??
Reply me soon... As it makes some trouble for me...

That pipe is the crankcase ventilation pipe. If you leave it open, engine oil will get dirty.
So, you should cover it with a layer of double cloth material for some "filtration" of the air that goes in and comes out of it, due to piston movement.

I had tried k&n filter with fz16 and honda dio with an free flow exhaust made by my friend..
But I never felt any difference with it..

Later I removed my old cd dawns filter box's cover then it sounds pretty good than that of k&n without changing the exhaust...

And now I dont feel that vibration when touching 60 or 70 on the speedo with that 100cc engine.
