While I'm waiting for a replacement choke plunger because I was a ham-fisted idiot and broke one of mine :sad: :
My local dealership cannot get me a replacement air filter from Emgo, they appear to be on backorder until leisure suits come back into style.
Off to Ebay where I can find stock filters, along with a brand called Uni and of course the pricey K&N.
K&N usually flows more air and I like the wash-and-reuse idea. But, if I have stock jetting will it screw things up? And, if I go stage one jet kit later on, will the K&N still flow enough air for that? I already have Supertrapps on the bike, should the air filter ALREADY be K&N because of the aftermarket pipes?
Or, should I stick to a stock-type filter because of my stock jetting?
I would go with one of the reusable filters, especially if you plan on keeping the bike for the foreseeable future . Most aftermarket filters claim to increase airflow, but I wouldn't say they would increase airflow to the point that would require different jets. Since you already have a Supertrapp on the bike, you might be able to increase your hp (ever so slightly) with a aftermarket air filter and different jetting. But it should run fine with most any air filter, your current jetting, and your current pipe.
I would use whichever one you can get easily .Wether it is a high flow or not the engine will dictate how much air it needs not the air filter . At a certain rpm you can only get so much air into the engine ,at high rpm's it will make a slight difference .

Buy a K&N and be done with it. It cost 5 bucks more but you will never have to buy another filter. No worries about jets or exhaust. The main reason to buy one is to save money. If you get a tiny bit of performance out of it great.

Easy enough....thanks!!!
Some will say a bmc is better than a K&N but it really just makes good sense finacially. I have a K&N on every vehicle O have ever owned. I dont loke to clean them but they seem to go a while before needing to be cleaned.
What I usually do is wash and re-oil at the same time and just get it over with. It's not hard just not much fun. For 5 bucks more than a stock filter it's worth it. I tink I put 100k miles on my trucks filter befor cleaning it. They say a slightly dirty filter develops more pressure and sucks more air.
What Doug (Soichiro) said...and also what Doug said on the BMC. get one of those unless they are more than $10 above the cost of a K&N then just stay with K&N.
If I can source the foam, I'd as soon do that. I like that idea very much.
The K&N for this bike is at least $60. The Uni is only about $30, as is Emgo and stock.
So it's way more than just $5 difference.
For my Concours I use the K&N and love it, durable with a 100k mile warranty, flows just as well as stock. Cleaning and re-oiling is not a big deal to me, no more than cleaning a chain.
But on my Nighthawk 750, anybody who installs a K&N has major jetting problems and ends up going back to stock.
That's why I was wondering about the best filter for this model. I don't see myself riding in such a manner as to need extra air. I'm a "spirited" rider, not a road racer.
OK I can definately source the foam locally, so I'm going to copy cat ya'll, and put two layers of foam in the stock filter housing. It still smells like the dead squirrel and pounds of nest I pulled out of it before the bike would run....really, REALLY gross when the bike is hot and you pull the tank.... :comp13:

before using the foam spray some petrol into it and leave it for a few days and see if it affects it in any way some time they will crumble and will end up getting sucked up into your motor and u dont want that. Posted Image

I don't know if your fiter is set up the same as a 3rd gen, but if it is, do as I did in this thread:
http://www.vfrdiscus...__1#entry649673
Since I can't get uni foam around here, I did the next best; I used a car filter, paper media, made for a 2liter nissan, fits the media frame perfectly as the foam edge is snug against the cavity. I still sealed the edges with high heat silicon. Best $8. solution I've ever used.
Be aware: if you ride where conditions are dusty you will need to clean these types of cotton filter media more often... well that being said you would have to replace your stock one more often also, lol... K&N, BMC etc flow more air, but will allow more(particulates) through in those conditions. They are designed to allow an acceptable amount of particulates through under normal conditions--small enough not to do damage to internals.
I got a UNI. i don't have big dollars for the K&N either, and have had good experience with the UNI's. i've got one for each nighthawk, and had them on my old yamaha. i don't do a ton of driving in dusty or dirt-road conditions, so of course adjust accordingly, but i feel comfortable using the UNI in just about anything i ride/drive.
Sure if a Uni falls into my path very cheap I'll pick it up. Meanwhile the local bike shop is pretty cool about ordering parts for me and gives me a discount for being a member of AMA...might as well just get some filter foam from them if the price is comparable...

Uni bulk foam should be WAY cheaper than a complete filter/frame. I spent about $20 on the green and the black together, but the nice thing is, there is about THREE filters worth of foam there! (and, that is stacked like in that thread I linked earlier). So, it's like $20 (or whatever your LBS sells it to you for) for three complete tow-layer filters.

No contest if you can use the bulk foam. :fing02:
Thanks, that's what I was wondering: what kind do I choose? OK, green and black, no problem. It's normal riding, not a lot of dust or anything.
And if there's extra, I can do up something for hubby's KLR too, which is still running stock.
Ya'll just don't know how bad my motorycycle smells, the dead squirrel odor is just so packed into that air filter....hey it keeps the theives away!
