found- proper 13" air cleaner

base with 1" drop that did the trick clearing everything (including hood) without need for a spacer, matching up with my unsilenced factory style top - Mancini Racing. FWIW.

Yes yes! I order a drop base for the air cleaner from them as well. Excellent clearance with the MP air cleaners.

hmm...thought about that lid as well - it does look good.
