Expert Pro-Tip: The Polaris 900 engine is sensitive to intake health. Before you start your rebuild, thoroughly clean your entire airbox and intake tract. Even the smallest amount of dust left behind will act as an abrasive, significantly shortening the life of your new piston rings and cylinder walls. Also, verify your oil pressure after startup; these engines rely on consistent oil flow to keep those high-revving internals cool.
