Questions & Answers

  • is the intake boot included on the kx 500 rad valve?

    By: G

    Yes, the intake boot is included with every Boyesen Rad Valve kit. You also get the boot clamp and gasket to go with it. It'll bolt straight to the OEM carburetor of any machine we have listed in our fit guide without issue, guaranteed!

  • What the intake size for the carb side? For a 2006 Yamaha blaster

    By: Guest

    Boyesen Rad valves are designed to fit the OEM carburetor. That is to say, the intake size as the same size as the OEM unit on your Yamaha Blaster.
