K&N air filter

Leave the stock airbox in place and just install a K&N replacement filter in
the air box. Then you will never have to buy another paper filter element.

Never remove the airbox.

The airbox is a tuned resonant cavity that helps smooth out the midrange flat
spot around 5000 to 7000 RPM that is so annoying with an inline-4 that has a
4-into-1 exhaust system.

I've installed K&N separate filters on two sportbikes, but I would never make
that mistake again. K&N separates are OK for drag racing, but you lose too
much midrange for canyon riding.

It's not worth all the hassle of re-jetting by installing larger main jets.
The average rider seldom operates his engine on the main jets anyway.

If you're going to tweak with your carburetors, learn everything you can
learn about the idle circuits and part-throttle running, because that's where
you're getting your fuel 90% of the time you're riding.

I replaced my OEM paper filter with a K&N. I didn't really expect a
performance difference and didn't see any. Their pod filters will flow more
air, but that opens a whole different can of worms. I got my K&N so I
wouldn't have to fork over big bucks every time I needed a new filter. The
K&N only cost about 1.5 times as much as a new paper filter and can be reused
indefinitely.

You've had better experience with oiled foam than with K&N ?

I went back to paper for mostly street riding but have wondered
about foam aftermarket.

What brand ? Easier to manage the oiling and get it right ?

Thanks

Two things:
I had a K&N on my Yamaha XT and I guess it hardly made brake even
economically. OK, it lasted as long as 2, 3 or possibly 4 OEM paper
filters. But - it cost more to buy, I got a clean and reoil kit that cost
like one
Yamaha filter and after a much shorter time than eternity the seal strip
on the edge of the K&N was loose.
Believe me, I really tried to fix a new seal or get the original one back in
place but I just didn't have any glue that could do the job.

My other point is the clean and reoil thing. No matter what K&N say, you
must wash the filter sometimes because caked on dirt, dead flies and
dried leaves will not pass much air. And after cleaning, you must reoil.
Oil too little and you have a screen that will not protect your engine. Oil
too much and you have a bad copy of water and windproof Belstaff
waxed cotton and an engine gasping for air. I never got this quite right
and because I'm a cautious man I had periods with distinctly sub par
performance.

Paper filters are good for street and oiled foam has worked fine for
me in the dirt, I'll pass on the oiled fabric ones, thanks.

Yes much easier, just saturate and then squeeze out the excess.
Not even terribly messy if oiling and most of the squeezing is
done inside a plastic bag.

Nope, not aftermarket, original Suzuki TS125X, Yamaha
TT600R and WR450.
