PROX steel intake valve conversion kit, specially developed for Yamaha engines. Designed by PROX, renowned for its engine components intended for competition and intensive maintenance, this kit allows for the replacement of worn intake valves during a cylinder head overhaul or engine preparation.
Steel valves are suited to the demands of off-road motorcycles and high-performance roadsters, where the durability of intake components is crucial. This kit integrates into the cylinder head to restore valve operation, facilitate clearance adjustments, and ensure a clean reassembly during mechanical intervention.
Practical compatibilities (examples): GAS GAS EC 300 F (2015), FANTIC TF250ES (2015), YAMAHA WR 250 F (CG30) (2014). Check the reference on your engine before ordering.
Installation advice: plan for inspection of valve guides and seats, machining if necessary, and installation by a mechanic or experienced enthusiast to ensure the sealing and longevity of the cylinder head-valve assembly.
