Does anyone know if there is an option to replace the cover that comes with the Mikuni HSR air cleaner cover? The old original air cleaner cover had a flat part that was against my leg. The Mikuni cover has a corner against my leg. My original cover does not even come close to being able to cover the Mikuni filter, so I can't just put the original cover back on. Maybe I'm just too picky? Has anyone else made the swap to the Mikuni 45 HSR and missed their old air cleaner cover?
