I recently acquired an '03.  A previous owner removed the air box and put a cone filter on the carb.  The also put a larger batter in it and hacked the batter box to fit said battery.  It now has the correct size battery and I bought a used box for it.  Thought all would be good.  Now I see that the top cover won't fit because it hits the cone filter.  
Is there another filter out there that will allow the top cover to be on?  Could I just get a stock intake tube and put it on the carb and cone filter on the other end so the filter would essentially be where the air box once was?  I like the looks of the filter on the carb but its not a must have for me.  I'm open to any solutions you all may have.  Thank you!

Thanks zipidachimp.  I'll see if if can find a #.  I'm guessing its just a generic.  I'll probably go ahead and swap it out regardless and see where that gets me.
