YOSHIMURA offers this power valve for HONDA CRF 450, TRX 250 FOURTRAX RECON 4WD, TRX 250 TE FOURTRAX RECON ES 4WD, TRX 250 TM FOURTRAX RECON 4WD, TRX 400 EX SPORTRAX 2WD, YAMAHA YFM 350 RAPTOR 2WD, YFZ 450, KAWASAKI KFX 700, KLX 450, KXF 250, KXF 450 and SUZUKI LT-F 250 OZARK 2WD 1999-2021. 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.

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.

• Yoshimura USA spare part
• DB Killer
• Manufacturer part number: SA-03-K

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.
