I want to replace my air filter (pretty dirty) to a stock or uni filter can somebody tell me whats the difference in those two? i dont want the K&N (not looking for more "performace") and wheres the best place online to get them since my local dealers dont carry the stock air filters ( weird guys up there) they said 30 bucks for OEM filter nad have to wait two weeks, i told them to eat it since i can probably get them cheaper and faster from somewhere else online, what do you think ?

·the filter is reusable. wash it out, then reoil with plain ol motor oil
Yeah, I'd wash and reuse it. Careful while washing it, I cracked the body of my stock filter, then made the mistake of getting a K&N to replace it. Didn't do the pilot screw adjustment, hated how the bike ran, and put a UNI in out of desperation. The UNI was closer to stock, but I still just want to get a new stock one in there.
A little information here:
Instead of blindly doing stuff by following the herd or reading the add copy, understanding what is happening and what you really want is a better way to go.
OK that said and the subject here is air filters, so I'll start in the middle. The air filter is another part of the intake system that has a role in controlling the relative vacume (reduced air pressure really) of the intake tract and therefor the relative pressure on the fuel in the float bowls. (this pressure is what forces the fuel up through the jets). So just like when (if) you did the airbox mod, mucking around with the filter can screw up the mixture.
Ok stop here for a moment. Notice nowhere in the above statment do I speak of flow , or increased air flow, or anything but pressure changes. That's because the only way you can increase the air flow into the engine is to increase it's capacity.
Since you have chosen to meddle with the intract tract you must rebalance all of the components. You should: Make a 1" hole in the air box ( see Fog's airbox mod) change the airfilter to the one of your choice (I tested only K/N ) un plug the pilot screws and tune them to obtain the best throttle response. To do only part of this process is to invite problems.
Even washing your stock filter can affect the running if you did any adjustments with the dirty one in place.
SO think ahead.

Just remember, 2.5 turns out is just a starting point. every bike will be slightly different.
Just wash it out with water and dish soap, let it dry out, and i BELIVE the manuel dictates regular motor oil, but not a lot. wring it out as best you can without breaking it.
