if you ride anywheres where it is dirty or dusty at all, you should ditch the k&n it doesnt filter as well as a uni .

Don't ever assume your jetting is fine, or go on just recommendation alone, always do plug chops to assure you are right on target. Each bike will slightly differ due to internals, geographical elevation, temps, etc.
As far as running with your Air Box lid off, definitely go with the UNI. And, make sure you clean the filter religiously and correctly after each ride, it's a must.

Have fun!!
