Sort of an after mkt air filter?

I know many here prefer to keep the stock paper filters in place vs the POD types that do away with the air box and crankcase vent, but what about the UNI thats just a factory replacement type? Any one using that type who could comment? I know they could be cleaned, although I have cleaned the factory one too- with a good degreaser and hot water.

No experience with the UNI. Another option for a cleanable filter would be to go with a first generation setup, which uses an oiled foam cover over a mesh basket. The covers last a very long time when properly maintained. Ebay usually has the used baskets available.

Keepin' all the left over parts. Gonna use 'em to build another bike!

K&N also makes an OEM replacement filter, although I have to say I became leery of these so-called "lifetime" filters after having one last a mere decade before it warped itself out of shape/resulting in air leaks, and then pulling teeth to find a replacement because the filter was discontinued.

I'm all for the 80's vintage Rebel filter cage with oil-soaked foam wrap, although I've seen the 96+ paper filters for as low as $10 as well. I'm also a big fan of the 80's battery box & air cleaner cover.

"Ride Safe, Chop Safer" Motorcycles are not unsafe. However; they are extremely unforgiving of inattention, incompetence, ignorance, and stupidity.
Dismantling, sawzalling, and rattle canning does not make a bobber.
Those are STEPS toward customizing, not customizing unto itself.

my experience w/the foam is that it does not last forever either. cleaning may speed up the decay? Am I the only one that has ever cleaned an original HONDA filter- with hot soap and water? This is sounding like the way I may end up going........

Yeah, the foam does deteriorate over time. Still, it outlasts a paper filter and costs far less than multiple paper filters. It may not last over ten years (neither will a K&N as I learned) but you can still replace them (unlike K&N as I learned).

thanks........

Im still playing w/the starting drill on this 04 Rebel with 6900 miles. Today I used no choke and it started- not like I love, but easier than trying w/partial choke or full choke. It his SO NICE with partial choke but for only a couple of seconds- IF IT COULD JUST KEEP THAT IDLE, I'd be a happy camper!

PS: Found a 2003 Nighthawk 250 w/only 2300 miles, original retired owner, not real close but I'm very interested........

I pulled out my air filter last night to see how it looks and blew it out while I was at it. Still looks good enough for now. I have bought UNI foam sheets from eBay and replaced the paper with the foam (and oil), on my Majesty. It works good on that ride as there are two filters to deal with. I may try the same thing on the Rebel when the time comes to replace the filter. I was like $12 for a sheet of 24" by 24"

I prefer oiled foam over paper, they are more efficient at filtering, and can be cleaned and reused a few times. I have a UNI filter (in the stock unmodified airbox) on my dual sport bike, and at the end of a day riding in the AZ desert it will be caked with so much dirt that chunks of oil soaked dirt have fallen off and are laying in the bottom of the airbox. A paper filter would have to be replaced, and they are not cheap. But on the Rebel, which is not ridden off road, the paper filter seems to work just fine. As for K&N, I wouldn't go anywhere near one of those things. They will stop small gravel, but that's about it. They are advertised as a high flow filter, and that means dirt as well as air. But you want to keep the same airflow as well. More airflow will lean out the air/fuel mixture, and the carb will have to be rejetted to compensate for it. Unless you are into that kind of thing, it's better to just leave it alone.
