YZ295 POWERVALVES $200

The stock Yamaha YZ250 powervalve system works great until things wear out, and the asymmetric movement and impact energy of the powervalves opening and closing through 2 stages is brutal! These aftermarket powervalves are designed to be replacements for any YZ295 converted from original like EGR, MILLENNIUM, and MAX POWER or a kit cylinder like the ones offered by MAGNUM, CYLINDER WORKS, and ATHENA. Includes 1 center exhaust powervalve and the left and right sub-exhaust valves for $200 by USPS
