Valve Kit MALOSSI
for YAMAHA 250-300cc 4-Stroke
When a “sharp” camshaft is used, the so-called intake duration increases. Thus, it is absolutely necessary to mount stronger valve springs as they will help in closing the valves faster. If you are looking for brute power increase, make sure to add flow optimized valves with larger valve plates. MALOSSI has a complete valve kit on offer and it lives up to their usual high quality standards, for LEADER engines the matching springs are already included. An absolute must for all 4-stroke power freaks.
Tuning valves (exhaust and intake valve)
Heat treated special steel, no/little heat expansion during race use, cam shaft coated with hard chrome for minimizing wear, larger valve plates, flow optimized valve design, valve seating and valve head featuring hard metal coating, ISO 9001 certification
SIP TIP: We recommend mounting a tuning cylinder in the process in order to save on assembly time.
