Nobody seems to have picked up on that and sorry if I am stating the obvious - but since you don't have many posts, you might be new to Dukes- better to check than you making a big mistake.
When you removed the filters from the airtubes, I believe that you fitted an under-tank filter (such as ITG / JHP / etc).
Don't let the airflow completely free cos the bike does pick up some crap and this is going straight into the engine if there is no filter on the way.
Just imagine the dammage that a small stone could do to your top end... It did happen to me once on a GoKart (you don't have air filters in Gokart, that would restrict airflow too much) and it was a carnage in there.
Again sorry if there is stating the obvious but better to do so then leaving you with a totalled engine!!
Cheers
