Damn.. That is out right pointing @ the fact that the K&N sucks.

Hopefully, having the prefilter helps?

what do you run preddy?

Nevermind, checked your sig.

A pre filter will help, but wont get it all.

I run a K&N with a pre filter, only because I will be tearing it down this winter for some more goodies. If I have a bike that I dont want to wrench on for years I would with out a doubt run a twin air.

I have done tear down on two predators both similar builds, one with K&N and one with twin air. both had pre filters too.

The K&N had a shit load of debris on the piston and the  cylinder was in pretty bad shape. the twin air foam filter bike was noticeably cleaner and in better shape.

$hit! Thanks for the info. I have never read anything bad about k&n before today. I will go twin next time I mod.

Foam filters don't flow like K&N,  but there is a reason for that.

understood.  Just need a good compromise between flow and filtering. Unless for drags, I assume, then go for the best air flow. I get pretty dirty when I ride, so better look into something new.

I say it's totally a toss up. Depends on the terrain your riding. if it's dusty, I switch out to my Uni, if it's rained recently and no dust, I run my K&N w/ prefilter. @ the dunes, I'll be running my K&N.

Last time I ran my Uni filter @ the dunes, :O SOOOOOOOOOOOO MUUUUUUUUUUCH SAAAAAAAAAAAAAAAAAAAAAAAAAND stuck in the foam..

same with the k&n. Sand everywhere-it was nasty. I think K&N is good for sand, it is the fine dust of the summer from dry dirt and gravel roads that is worrying me.

Ive used K&N on my 660 and now my 700 with a prefilter. Everytime i clean it(which is after every ride) because of extremely dusty conditions, I use a white towel and wipe inside of the intake as far as i can reach. It has always come out clean. They may not be the best application on cars/trucks in dusty conditions as most don't use a prefilter on the street. Until i see some proof inside the intake of dust or dirt getting by ill continue to use one.   Very good read though.

I'll do that the next time I clean it. Come to think of it. Mine did not look exceptionally dirty.

I also run with a EHS airbox lid. I ran without a lid a few times and my airbox was coated in dust and dirt but my intake was still spotless.
