A part of the exhaust power valve, the system that gives a two-stroke low-end torque and top-end power.
YOSHIMURA offers this power valve for YAMAHA YFM 700 RAPTOR 2WD 2006-2009. 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.
Specifications and fitting tips
- Manufacturer part number: 2388-144-A
Cross-Mania tip: Check the diameter of the supplied or required piston and replace the top-end gaskets. A big bore may require carburation or fuel-injection adjustment.
