Whats stopping me or anyone for that matter just buying a k&n filter like so...



and just slapping it on the end of my carb inlet?

Mind you i have an SF so it is street ridden only.

K&N makes every size known to man so i dont think finding one to fit will be a problem...

Is there a reason this hasnt been done or just no one has done it yet.


on my old buell blast i got rid of the airbox completely and did the same thing...like so




so ideas?

 

No issue doing it, for street use.

But no good for riding through deep water.

 

alright! its gonna be done!

 

Gonna be done? I have a BMC filter on my D-tracker. Airbox is completely removed. The intake noise changes from mellow to a bit raspy. Whatever filter you get needs to clear the top of the cross member immediately in front of the carb intake. The filter you show might work. I used an oval-shape BMC with an offset throat. I'm pretty sure K&N makes the identical size and design.

 

why in the first place? is it really worth going to that effort of a 250 and stuffing around with jetting? also i remeber when i took the lid off my bike and it didnt like that, wouldnt start missing etc i imaging what it would be like with out the box.

why not just remove the lid.

couldnt see why it wouldnt work. dont forget about rain as well.

 

i got one in my deff more power then foam. i had a no toil drop in, installed didnt fit right cause they dont make an exact fit. the k&n is an exact fit part number and where at is in the sticky post.

 

Have done it to a dozen bikes. It will behave funny in the rain, running rough when you first open the throttle until it sucks enough water off to pull air through. You will also need to put in water remover(alcohol) in your gas or drain the float bowl occasionally as drops of water will collect in the float bowl and screw up starting and low rpm running. I like K&N better than foam because they don't catch fire if you get a backfire through the carb although the foam guys claim better breathing and cleaning. I'd do it for the clean look and raspy sound if I didn't live in the rain capitol.

 

Well my bike doesn't see rain....so no problem there

 

Never? You never ride in the rain? It has never happened where you didn't think it would rain but it did? If not, how long have you been riding, because stuff happens and you WILL get caught in the rain one day. Just saying, the slight benefit may not be worth the risk IMHO.

Also, washing the bike requires you to cover the pods and often in strong cross winds the pod can be starved for air.

 

I use my bike for basic transportation to work and so forth. So i check the weather...if its gonna rain i drive my car...simple as that.

And even if i do get caught in the rain one day a K&N filter is water resistant and its under the seat so i really dont see it as being a huge problen.
