  Boyesen Super Stock Carbon Reeds

  Brandon in TN

  +++

  Tried the vforce 4x reeds and they were great but they kind of mellowed out the low-mid punch these fi bikes have. The bike did rev out a little better on top but I felt like it lost too much low-mid. So I put these Boyesen reeds back onto the oem cage and they seal much better. 100% recommend

  Boyesen Supercooler Water Pump Cover and Impeller Kit

  Bruno in UT

  Feels worth it!

  Overall satisfied with the purchase. Note: when tightening the impeller, it broke down and I had to eventually replace it. Please be careful as mine broke even before torque specs. It does generate more pressure on the system, so you will see more spillage. When installing these, make sure to get a higher pressure cap (ideally 1.8 with the thermometer). My next step is to get bigger radiators as the weather is about to get hotter in Utah. Again, this paired with 1.8Cap and EngineIce, made a big difference in terms of temps. Feels like a worthy investment.

  Clutch Cover

  Clean Factory look. Comes with a gasket and is more durable that stock.

  Boyesen Super Stock Fiber Reeds

  MIchael in CA

  Good quality item, perfect fit, nice peformance.

  Replaced worn out reeds on a 2001 Honda CR500 with these Boyesen Super Stock reeds. Easier starting, crisper throttle response, and it fixed some of the throttle blips when chopping the throttle to idle, and air/fuel charge can still get by the curled edge of worn reed. On a 500 those little decel throttle pops have enough power to throw your balance off in a turn.

  Boyesen RC2 Series Rad Valve

  Kelly in UT

  Great!

  There's not a lot of reviews on this, so I was skeptical. I scoured the internet for information on it, and most were extremely positive. Seems like its more durable and will last longer than others.
