Ear Shave --- Air Filter Question

Doc's Ear-Shave mentioned he got K&N Air Filters RC2340...


I am curious if I could use any universal air filter?
like these: 54MM CHROME AIR FILTER Cone Kawasaki KZ750 900 1100 Motorcycle Bike I AF25


I don't want to spend almost $30 per air filter just yet ... I still need to get some pilot jets and fuel line and some vacuum caps ... plus a few other things to get this bike running again.

Those look like they could work. Many people on here have used various different filters on here with good results, others with not so good results. The only member that stands out in my mind that went with a cheaper filter that worked good was Wolfie.

I know he has chimed in a few times on different posts on what he used and I think he more then stands behind his choice from what I've read. I don't recall off hand what he used, but I'm sure a quick search on his user name will pull up some of his post no problem.

......I'd rather wake up in the middle of nowhere then in any city on earth.

Thats what I remember reading, I know which ones he got too I believe... its those cylindrical black foam ones.

I'll get those if really absolutely necessary but I don't like how they look... I am going for function after all so if these chrome cone ones don't work too good I'll simply get the black foam ones and skip out on looks. :P

You dont need to rejet for an earshave. As far a kn filters go, they fit. Not just the neck, but under the tank. Keep that in mind. Any airfilter that fits will work.

the UNI pk-92 works well. they do just touch the bottom of the tank, but a washer or 2 under the back of the tank fixes it.

these are what I am running on my bike.

Wish I would have read a bit more before ordering the jets and shims lol! But oh well, it probably needs done anyway and I'll probably be happier with the end result if I do.

If I can work out the kinks in the loud tapping noise I'll have a bike worth every bit of 2 grand.

My Left side K&N pod presses hard against the tank. When I earshaved and tried my stock 38 pilot jet (it was very clean) I suddenly was running very lean in both cylinders even with the air screw 3 turns out. A size 40 pilot jet fixed the problem with the air screws 2 turns out.

Every bike is a tad different.

I ran 2.5 turns out with no problems at all and I'm only 600 ft above sea level.

OEM pilot jet is a #38. If you actually ran a #30 w/#95 pilot air bleed, you would have been dangerously lean.
