K&N Air Filter Queries and Doubts

Re: K&N Air Filter Queries and Doubts

I have a small query here. How can a single universal air filter be a fit for multiple bikes????. Yes I know that IT SAYS UNIVERSAL. But for instance: the 153cc of Yamaha FZ will not share same technical characteristics and output with that of a Unicorn or HUnk or anyother 150cc. Considering that, how do you THE UNIVERSAL FILTER is advantageous???

Re: K&N Air Filter Queries and Doubts

Its a common misconception. Instead of saying they draw more air, the better term would be that k&n filters allows the air to pass more easily thru the filter. So when the engine is sucking air it requires less work and hence its easy for it to do so. If you go for stock replacement filter, re jetting is not required , if you go for performance filter re jetting might be reqd.
i have a pulsar 200 ns and i have a conical type performance filter installed. No re jetting(jets were already big & similar to 220) , still power mileage both have increased, and no issues of carbon deposits on the spark plug or engine over heat, or similar issues related to running on lean mixtures.

How about k&n rc1100 in pulsar 200ns can we fit in filter box pipe if so it will improve performance or direct in carb..... ?

Re: K&N Air Filter Queries and Doubts

Air flow through a stock replacement filter (SRF) is dependent on the stock air box too. A SRF in a stock air box does not flow as much air as an open conical air filter fitted close to or directly on the carb. Therefore jetting is not required. Air flow can be increased by drilling holes on the air box cover. Then jetting is required in most cases.

Mileage has increased?? By how much? Doesn't theoretically make any sense.. More air drawn means more fuel required to avoid running lean.

Re: K&N Air Filter Queries and Doubts

Sorry but I am kind of noob to this air filter world. Why isn't the rejetting requured? I mean doesn't this filter draw more air than stock and to compensate that isn't rejetting required? Or just carb tuning is enough?

Gyan, rejetting is not required if you go for the K&N model E-0900.

Re: K&N Air Filter Queries and Doubts

K&N are normally mental threaded airfilters,
Filters like UNI ( I preffer pipercross) are sponge based.

Sponge based filters are better for dusty conditions, but you need to remove them often and clean them. else they will choke up and not be able to allow air flow.
Also note that Sponge filters don't last that long compared to metal ones.

Also a k and n should suffice to normal dusty conditions, unless you have real off-roading or live on a beach driving then i think you should worry.

Thank you for the reply. I have classic 350, so what would you suggest. Also is rejetting must after installing K&N? How much mileage drop one can expect?

Re: K&N Air Filter Queries and Doubts

Guya i installed the k&n rc1060 on pulsar 200ns by removing the airfilter box and installing directly on carb, now the cab is connected via the engine by a rubber pipe(almost similar to any other bike) but the carb and conical k&n are both balanced on the rubber pipe. The pipe is made of strong material but and is designed to take tbe weight of carb. But what i wanna ask i does the added weight of the air filter, is going to create any problems, like the pipe coming off the engine or sumthing.

You don't need to worry about anything.
The Air Filter is not that heavy, it should not cause any problems.

Guys which one is better between K&N and UNI. I read and heard that UNI is better for dusty conditions (which is very much prevalent here in India). What is your take on this?

Re: Which K&n Airfilter is best for P220? R1100 or BA-2201

I'm looking to install K&N 1060 in my Unicorn. I understand that it needs up-jetting. Does up-jetting mean that I should buy a new bigger size jet for my carburetor? Or is it just a tweak on the carburetor?

Where can I get the K&N installed and up-jetting done in Chennai?

Re: Which K&n Airfilter is best for P220? R1100 or BA-2201

Hi, there is no Stock Replacement Air filter for the Stunner. the RC1060 fitted directly on the carb is the best option. Needs rejetting though.

Thank you for the info
