§ 02 / About this part
What it is
The PROX VALVE AND SPRING INTAKE KIT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This kit replaces the intake components in your cylinder head during a top-end rebuild. High-velocity air and fuel wash eventually wear the valve faces, leading to hard starting and loss of power. This kit includes steel valves and matched heavy-duty springs to restore factory performance. Steel conversions provide a longer service life for riders prioritising durability over marginal weight savings. Ensure your valve seats are checked for a perfect seal before installation. Always fit new stem seals when rebuilding the head to prevent oil leaking into the combustion chamber.
