Duckndive Posted February 4, 2020 Share Posted February 4, 2020 I destroyed a 1260 hybrid at East Kirkby due to no filters so I use these on stacks on Micky Roonies now ... 2 Quote Link to comment
Gixer1460 Posted February 4, 2020 Share Posted February 4, 2020 Agree with Clive - at the Pod you'll get away with stacks (maybe if you don't ride back - top end ain't that clean) anywhere else deffo use filters or an airbox! I had a rock trap the butterfly open on an S&S in front of the turbo at East Kirkby which was fun - NOT! 1 Quote Link to comment
caferacerdan Posted February 5, 2020 Share Posted February 5, 2020 ive got stacks with mesh covers for my Harris. kind of compromise between power while still having some protection 2 Quote Link to comment
