Many two-stroke engines have an exhaust power valve: a blade that changes the height of the exhaust port according to revs.

Why replace this part?

The benefits:

• An engine that pulls low down and up top again.
• Replace a worn, sticking or broken part.
• Precise valve operation at all revs.

Why choose YOSHIMURA?

Founded in Japan in 1954 by Hideo 'Pops' Yoshimura, the brand won the very first Suzuka 8 Hours in 1978. Its American branch, based in California since 1971, has collected more than 30 AMA, WORCS and GNCC titles since 1999.

When should you replace this part?

A scored or oval cylinder, or one with damaged plating, loses compression and wears the piston quickly. Measure the bore at every top-end rebuild: beyond the wear limit the cylinder must be replaced or resleeved.
