I heard that K&N Air Filters are good for the bike... Can anyone explain the advantages of having such an expensive filer; what makes it worth the money?

http://www.rc51.org/airfilt.htm food for thought.

IMO, they are a waste of 50 bucks. I had one on my EX500. This question has been posted on the 500 site and the SV650 site before and they all cam to the same conclusion.

The K&N lets more dirt in, it's exensive, more time consuming to clean, and gives no power increase for most bikes.

The OEM is cheap, easy, gets you back on the road quicker. As you'll read from that link, Honda airboxes are more fussy than most.

Ok, now someone take the other stance and beat me over the head! :D

I'm not going to completely disagree but I will say that putting a more free flowing air filter will actually be detrimental to your performance without a rejet. The bike already comes with a lean mixture and if you allow more air into it, your bike will take longer to warm up (stupid carberators), have a rougher idle, and possibly stall out more often.

Wow! I'm glad I asked. :shock:

yeh I took my K/N back out after I put the exhaust on but once the DJ kit arrives its going right back in :shock:

My friend just iron man ed the baja 1000 on his 650r like my honda!!Honda team used to have k and n air filters stickers all over there bikes but in reality they used stock honda air fiters why???In the dirt they would clog up and the bike would not even run!!!!! On the street you would be alright but I would think you would have to rejet the carbs just my two cents!!!!!!!!!! :roll: :roll: :roll:

not sure about bikes but in cars and trucks the oil in the filter can hit sensors in the intake tract and foul them up!

yeh if you over oil the filter the excess can get on the mass airflow sensor and affect its readings ..... I use a K/N and I think if you use it correctly keep it maintained properly you can benefit but to some it just isnt their cup of tea

...excess can get on the mass airflow sensor
No issue with the 599... Oil away!

Glad I read this before ordering a K&N. The RC51 link definitely helped too. Thanks Steve :thumbsup

I'll just stick to the OEM filter.

BTW Steve- the Victory mirrors looked great!
