ran my 800 for a year in minitwins with no filter

back to back dyno runs showed a 4 - 5 horse increase all through the curve without one

had a good classics set up in the w100 club .. always liked the look and sound of the open carbs

admitedly i'd be a little nervous just having the throttle bodies open to the atmosphere at least the airbox affords some protection
