Please don't get me wrong K&N's have thier place...its just not on my bikes...I'm looking for motor mongevity

 

if you read the fine print on a-- K&N filter they say that they work better dirty and not to clean them--- so i would honestly say to go foam if you want some extra power get a pipe and jet it ,,and change your front sprocket 1 sz down that will give you a little bit

 

I TOTALLY AGREE WITH PIMPT250R. THESE TOYS COST WAY TOO MUCH MONEY TO RUIN OVER A LITTLE HORSEPOWER. WHY CAN'T PEOPLE JUST BE HAPPY WITH WHAT THEY HAVE AND ENJOY RIDING OR DRIVING THEM.... INCREASE POWER MAYBE BY JETTING AND PIPING IT AND RE-GEARING IT LIKE PIMPT250R SAID. A HONDA WILL LAST FOREVER AS LONG AS YOU USE A FOAM FILTER AND CHANGE THE OIL WHENEVER YOU CAN.. I HAVE UNGODLY AMOUNTS O MONEY IN MY 9 BIKES PLUS 2 SEADOOS, A BOAT, A 75K SANDRAIL. I SAY 110% FOAM. PROTECT YOUR INVESTMENTS...! GOOD LUCK!!

 

I guess the Honda forum isnt the right place to go for riders who want the most performance from their atv, I should have realized that before I posted.

Sure if you're running in extremely dusty or wet conditions foam is the way to go, but the rest of the time there's not much difference. Especially if you have a prefilter.

But this guy has a K&N and just wanted to know how to clean it, he didnt want to know RacinJason's personal opinion that the filter he owns is junk.

 

If you don't like it then leave, nobody asked for you to be here. We're just trying to help and the honest truth is that k&n filters just aren't that great for quad applications. He was told how to clean it, then some of us simply suggested that if he cares about the longevity of his engine at all he might want to consider running with a foam filter. A properly cleaned and oiled foam filter flows plenty of air and is about the best protection you can get for an off road machine. I don't know about everyone else but most of the time that I am riding it gets pretty dusty and I want the best protection I can get even if I lose 1 stinkin hp over it.

 

LMFAO... No $h!t. I was just curious as to how sand and debris get through a paper filter as opposed to foam that have larger holes in the first place? Is foam the way to go? I was thinking about going with a K&N with a prefilter. Would this be better protection than foam?

 

I wish they made paper filters for atvs. If they do I've never heard of them. The best protection is from paper, then foam, then K&N. I run a K&N on my mustang but it stays on the road all the time and is drivin only occasionally so I think its approriate. I did run a K&N in my truck which stays off road for the majority of the time. I ran it for about 20,000 miles and you could see a light coating of dust in the intake piping. This did not happen with a paper filter. I hate foam filters. I hate lookin at them and I hate cleaning them but thats what I run in my 400ex because it certainlly provides the best protection available.

 

Depending on your machine and how it's set up, I don't think you would even lose 1 HP. On a stock Rancher 350, dyno test showed that installing a K&N filter alone only produced a 0.4 HP increase and Torque increase was about the same.

 

Well I've been running a K&N on my bike for 7 years now with no troubles or adverse affects from the mountain of debris flowing free through my filter!!!!

Foam may offer better protection, but it doesnt flow as well dirty as a K&N, and when talking microscopic side particles of dirt, is it really going to affect the engine that much??? My 7 year experience says no.

To each their own, but to tell the guy his filter is junk isnt right, it will work perfectly fine as long as your not using it as an open element in dusty conditions.

 

K&N filters are junk on quads buddy. They let dirt in, I've personally seen dirt traces in the intakes of a bikes running a K&N filters. The FACT is foam filters are much better protection, in my opinion easier to maintain and thats what most people I know want. K&N belongs on the street and thats the only place. Just because you have it doesn't mean that it's good. Did you really ask if dirt entering your engine will really affect it? WOW.. Now that is kinda funny right there.
