I drilled out the slides today and removed the mini filter that Triumph installs on their bikes. I replaced it with a glass replacable filter from JP cycles. After drilling the slides you could tell the difference. The throttle response was quicker and there was less burbling when down shifting. If you haven't done this modification yet get off your duff and start drilling ......Angelis
