No probs...Even I had initially got taken by their hype.But I started to think if K&N was as good as it claims ..then how come no performance motors use them . I did a lot of digging and got answers. I posted regarding your query because K&N is not good for our Motors and WE END UP PAYING A LOT OF MONEY FOR A NO GOOD FILTER . On some of the forums K & N did reply saying that their Filter actually allows more air to flow etc., and keep repeating them like a parrot. Not once do they own up to their filters allowing more dust particles instead of filtering them.
So it is best to stick to stock filters , and may be replace them more often,rather than spending on useless K&N.

Air box of modern vehicles are designed to flow more than the motor's requirement. THE AIR BOX ON MOST VEHICLES ARE TUNED FOR SPECIFIC needs,of the motor. They best D I Y,can be an inlet resonator prior to the fuel charge entering the engine. Like the YAMAHA Y E I S on RX 100 ( abroad) or like the one in KB RTZ .

Before we stamp any black and white opinions down lets backup a bit and evaluate all scenarios first. If you ride around on a modded motor, you WILL see a performance benefit from a free flowing filter like the K&N, theres no rocket science there. You dont see race engines running around on stock airboxes do you? So its always a question of what do you need for and out of your motor and then you weigh the pro's and cons. I ride around town on a very wickedly fast Apache that will take most rd350's in the city (forget indian bikes) and i run a K&N...it plays a role in my setup and adds to performance. I dont ride around in or around muck nor do i do long rides, i see very little mileage but most of it is fast paced. My engine will see a full overhaul long before any detrimental effects of a free flow filter set in and even that will take a couple of years...so this filter suits my needs. Why the explanation? to illustrate that there is an application for lots of things, including filters like the K&N. Does it make sense in my opinion to slap on a K&N on a stock motor? No.

Dear Killer.....Like you quoted We don't see Race engines with stock air boxes....OR WITH K & N. Another quote from you " Does it make sense in my opinion to slap on a K & N on a stock Motor ? No." Precisely what I was trying to say.

ROCKRZ

on a stock motor, the k&N makes no sense except for the roar..

the longer cleaning interwal is bullshit cos after some time, when the filter is a bit clogged, it no longer remains a free flow filter, and after some time, the bike tends to run over rich with the clogged filter and cause carbon deposits so on stock bike, k&n is strict no no unless, if you clean the filter every month and if you never go dusty off road

You said your bike is a suzuki Apache (RTR) and you will beat yamaha RD 350 ? The RD 350 is a 350 cc TWO STROKE TWIN cylinder engine.It has no dead stroke, whereas your Apache(RTR) is at best a 180cc Four stroker, with THREE dead strokes to one Power stroke.There is no way you can outrun a RD 350 unless it's engine is in worn out condition. The RTR can never be a Race engine since it is made for normal day to day riding. A 500 cc Race engine makes 100 bhp or more.The Race engines are PURPOSE BUILT to perform and can do a wheelie on the 5th gear...Such is the power delivery. The mods we do to street machines can never make them true race engines.

Did you click on his signature by any chance.... He wasnt talking about a bone stock RTR...
PS: There are people around who have not-so-stock-and-yet-not-too-radical RTRs around...

I Know that there are many people in XBHP with performance bikes and I had seen Killer's garage. He has a very good collection of performance bikes and that's why it surprised me when he stated that his Apache can outrun a RD 350. He himself rides one and knows it's performance.....not to mention his other great bikes. I think what he means is that he and his Apache are tuned to each other to the extent of being the perfect pair.The point I was trying to make is that a street bike has limitation on the engine,Chassis and suspension setup, while a purpose built Race bike doesn't suffer from these......and to the best of my knowledge none of the race bikes(HONDA,YAMAHA,DUCATI,APRILLIA, etc.,) use K & N.

Killer

ok...whatever you say
