V FORCE and BOYESEN reed blocks for KAWASAKI KX two-strokes

V FORCE and BOYESEN reed blocks for KAWASAKI KX two-strokes

Reed valve blocks for KAWASAKI two-strokes: V FORCE 3 for the KX 60, 65, 80, 85, 100, 125, 250 and 500 and KDX 200, BOYESEN RAD Valve blocks for the KX 65, 85 and 100, and BOYESEN carbon replacement reed petals.

The reed block lets the mixture into the crankcase and stops it flowing back out as the piston comes down. V FORCE and BOYESEN blocks flow more freely than the original and improve cylinder filling, so the engine pulls harder at low and mid revs.

A cracked, chipped or warped petal makes the carburettor spit back and the idle unstable, so check them at every service. Some blocks also fit the SUZUKI RM 60, 65, 80, 85 and 100; fitment is given on each product page.

For the KAWASAKI two-stroke intake: reed petals, carburettors, carburettor repair kits and jets.

Use the vehicle selector at the top of the page to display only the parts that fit your bike.
