Faito Manual Timing Chain Tensioner - Yamaha Mio

Faito Billet Aluminum Manual Camshaft Timing Chain Tensioner has a rounded tip for reduced wear and friction. A manual timing chain is required if your motor uses a stroker crankshaft kit, or thick block gaskets which uses a longer timing chain. This adjustable cam chain tensioner for the Yamaha Mio/Ego/Luvias/Fino 110/115/125, and Yamaha Nouvo (non liquid-cooled) scooters (2 valve) extends an additional 12mm over the standard factory unit.
