Well, it's been 7 days now that my Spyder is in the shop. (Del Amo Motersports) in Redondo Beach, CA. Started with a small oil leak after every ride. They found oil in the air box, but could not explain why. I saw the fixes suggested here but decided to let the dealer handle it since I have the warranty. They called BRP, they recommended against the foam, but said to remove the HEAD and inspect the cylinders, sounds pretty major to me, but there is no charge, so let them work on it. If they still can't figure it out, CA Lemon Law comes into play. :lecturef_smilie:
