Duckndive Posted February 4, 2020 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
Gixer1460 Posted February 4, 2020 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
caferacerdan Posted February 5, 2020 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
