i'm thinking of getting a k&n air filter they say it'll fit straight in without the need to dyno,anyone out there fitted one if so what was the difference
any improvement in power or delivery
i'm really looking for something to smooth out the lower end,my bike seems to really hate going slow (this excuse cant be used in a court of law)
appreciate any feedback..thx

I just ordered one ill let ya know when i get it images/icons/grin.gif

chase - my bikes yellow and black so it should run pretty similar to yours graemlins/bounce.gif let me know when you get it
cheers graemlins/thumbup.gif

well i dont get it in for about 2 weeks i think..i ordered it with new brake lines, pads, sprockets, tires,chain..so it will be like my bike is new after all this stuff comes in. i cant wait.

some say its not worth gettin the k&n. i did and it ran lousy at first, so heres the fix:


cleanse the unit with a non-amonia-based cleaner - (dish soap) and let it dry or GENTLY use forced air - not @ high pressure though....next spray with a degreaser and repeat the above. At this point you've removed all the oil from the gauze. Simply replace it once dry and DONT re-oil. The gauze is more than enuf to stop the particles of debris- look at the bmc filter - it has only one layer of gauze compared to the k&n filter of two layers. This is a secret used by many from back in the day to squeeze a little more out of the bike while still being safe. <font size="2" face="Verdana, Arial">Thats my 2 centavos on it and mine SEEMS to be jus dandy. mine ran much better afterwards, but was alittle rich already!! u might need to retune, ya never know.

I have a k&n with full muzzy race system, i had to get a jetkit installed, due to getting large flatspots in power from 5-6.5k revs in the colder weather (in the warmer weather it ran alot better)
But after installin the jet kit, it runs even better now..

There is a good reason to oil a K&N filter... The oil stops the dirt... Yes it will not flow as much as if you had no oil... but, more flow = more dirt in your motor...

Make the call...

The oil helps maintain the gauze material firstly and secondly holds the debris. if it was up to the oil to be the sole line of protection, then ALL filters would be oily or need to be oiled. ya know??????
the bmc filter is even thinner than k&n and doesnt need oil!!

Well a BMC filter is really bad for your bike... lol It doesnt do a very good job as cleaning the air... Thin filters really suck... lol Will it do its job? Yes... Will it do it as good as a K&N, No. That is why the BMC makes more power.

It all comes down to the fact, are you willing to take a chance with more dirt being able to get into the motor? The extra power isnt worth it to me, and since I live in the desert, I am going to make sure I have a good amount of oil to stop dirt with... images/icons/grin.gif

Price: £30.00

Suitable for GSX-R600 WW-WY 1998-00
K&N replacement air filters are designed to fit right into the standard OEM airbox. No modifications are required by the owner, no jet changes or adjustment of the carburettors is anticipated or suggested. Customer modification of the standard air box - removing the cover, drilling holes into the side or top will have a drastic effect on smooth carburetion.

K&N filters are washable and never need replacing. They give better protection for your engine and improved performance.

All filters come with a 1,000,000 mile guarantee!!


it doesnt seem to be a resounding yeah "get it your life will be complete" but i'm still tempted
the oil on the filter will only be keeping the rain out of the engine in the uk!!!
thanks guys

Just my .02, correct me if I am wrong John. But It doesn't really pay to do the filter if you aren't going to re-jet the bike to take advantage of the added air flow of the k&n. I did the K&N and Factory StageI jet kit at the same time and it made a world of difference. I Also had a full system Micron Exhaust too before I did the jet kit and filter, so everything went together real nice. Hope that helps images/icons/cool.gif

thx
i've got a stage one jet kit fitted and a scorpion race can thats why i thought the improved breathing might help

John

okay okay john images/icons/blush.gif images/icons/blush.gif ......... dirtbikingly speaking, id NEVER do this. but id also use a good set of prefilters on the dirt (or as on my polaris race prepped ski)--thats not 2 say there isnt dirt in the atmosphere on our public roads, but a much lesser of an oppurtunity to injest any harmful particles - images/icons/wink.gif images/icons/wink.gif
i think we can agree the k & n is a good product; mine is less oily than others, but is also (more than likely) more often cleaned, inspected, and reinstalled as well. Still think u r the man - (IMHO is not gonna damage anything to do this or the bmc filter would be lethal) graemlins/bounce.gif graemlins/bounce.gif

<font size="2" face="Verdana, Arial">Yoshimura recommends the BMC filter in their book of speed as well as their online store with ALL their pipes. images/icons/confused.gif images/icons/confused.gif Who knows better than them?? Okay, probably the GSXR fReak does, graemlins/thumbup.gif but not many others do!!! graemlins/bounce.gif lol - jus ribbin onya.....

I am not saying that the BMC doesnt make more power.. I know it does...

BUT!!!!

To make more power it needs to flow more air, Correct? The way it flows more air isnt by some new "space age" filter paper. It is by using a thinner paper... Thinner paper = less filtration... = more dirt in your motor...

Sure it might not be enough to worry about, but I would rather stay with the oiled filter to make the motor last longer and make 1hp less... images/icons/grin.gif

But if you are running the stock jets you should re-jet if you change anything... Does this meen that if you dont rejet the bike wont work? NO. It will just work better...

If you have a pipe and a high flow filter, you should be willing to jet the bike for that setup...

John

cheers john
appreciate your input man

Motrac in Ellesmere Port don't recommend changing the filter in the 600, in fact they don't recommend a Dynojet kit either, just change the jet sizes to suit. Bearing in mind these guys sell dynojet kits and K&N filters, if they don't use 'em on the 600, there must be a reason for it. Either that or they're too lazy to fit 'em images/icons/wink.gif

dOOds.. look at the advertisment that k&n is putting out, "you'll feel the difference, "adds horsepower to ANY engine" this is bull shit, dont waste your money, the stock filter is the hot tip...you dont see k&n filters on ANY nascar, superbike, or any other type of full out race team...why???? good question...

there more hype than anything else....k&n came out when air cleaners and boxs were very restrictive..since about the 90s, you dont need anything, the manufactures have figured it out..

and now k&n is making oilfiters to make a buck..

you dont need a k&n, you can actually lose H>P> with them...check around, theres testomony(?) on the subject on this site and others to this fact..

you notice theres no guarantee for a horsepower improvment!!? even though they say it will give horsepower...think about it..

He is correct... You could loose HP with the K&N. You have to be able to tune the bike for it...

I opt for teh K&N because I like to me able to clean it and use it over and over.

John

K&N will slow you up a little off the line, but will give you more top end at high rpm. However if you dont have a solid seal from your ram air to your air box, it won't take effect till about 120 m.p.h., because you lose pressure in the box. That's what I have been told.

Ryan

yep, you could take OFF your air filter and your bike'll run like shit if you don't tune it.. if you don't want to jet/ map then don't buy an aftermarket filter. takes time to tune it correctly to your machine. once it's tuned right though, I promise you'll have HP gain..

First of all you ask why no huge team such as nascar or any super bikes use k&n?
simple becuase there engine are free of cost and desighned at most to run 4-5 races.

and 99% of race bikes and cars DON'T EVEN USE AIRFILTERS, at a super high competition level,

gsxr freak is completly right!

my KnN works great. keep that baby clean and oiled

LDH from ROGUE site did the dyno run back to back...and discovered that the BMC air filter he installed actually made the A/F ratio richer...I repeat....the bike ran rich...so...it's a no no for RC owners to install an aftermarket air filter...unless you are willing to sacrafice performance for reusability

the same has been tested and found of the k&n filter, richer a/f readings (which is why to remove the oil) ...unless you live in the desert!!!!! images/icons/rolleyes.gif images/icons/rolleyes.gif images/icons/rolleyes.gif

I'll go with the FREAK on this one. No one is claiming that a K&N makes more ponies than a BMC. It's just that a K&N lasts longer, is re-usable, and saves engine damage from dirt (because of the oil). images/icons/tongue.gif

ferrari, you need to go to some races...nascar cars use air filters, and so do superbikes....i cant believe you said they dont...they may only run the engine once, but theres still a airfilter in there graemlins/bash.gif and it aint a k$n.... graemlins/piss.gif

gsxr freak is completly right!<font size="2" face="Verdana, Arial">I second this notion. John completely has been hitting the nail on the head here fellas! I have a K&N and I love it since it is totally re-useable.

if you have a jet kit and a can already, get the K&N! why not unleash the full potential?

i guess all those engine builders(pro)and crew chiefs are wrong...how could they ALL be missing this great horsepower getter??

maybe the last two guys that wrenched on my engine had their head up their ass...one is a tuner for a ama superbike team... images/icons/confused.gif
