what kind of oil filters do you guys run? yamaha by me wants $16 a piece. i bought one because i was in a pinch, but i dont want to do that again. ive read some mixed reviews for the emgo filters online and mostly good things about the Hiflofiltro's, and that they are basically K&N's. i also see Tusk makes oil filters as well. just curious to see what you guys are running since i havent really seen a oil filter thread on here.
