  • Boyesen Supercooler Water Pump Cover and Impeller Kit

    Boyesen Supercooler Water Pump Cover and Impeller Kit

    Lincoln in MA

    Nice pump that I'm hoping solves my coolant loss is...

    Installed this on my son's 2007 crf250r that we recently rebuilt and looses coolant out the overflow. We had cleaned the radiators and installed a new OEM cap to no avail. Although this pump appears to be helping (only lost 4 oz on the last ride), the weather is now cooler than it was this summer. You can definately tell it circulates more coolant, but not sure it has solved my coolant loss problem entirely. We only fill it to the top of the fine when level, not to the neck.

    Fits great! The orange really stands out among the drab engine metal.

  • Tusk Clutch Kit With Heavy Duty Springs

    Tusk Clutch Kit With Heavy Duty Springs

    Michael in GA

    Good replacement

    Installed the Tusk Clutch Kit with the heavy duty springs on my wife's xr100r after installing a big bore kit. The clutch has worked perfectly so far through the break in of the engine and a couple rides. The heavier springs did give the bike a little stiffer clutch pull but that's to be expected.

    Tusk Top End Gasket Kit


    I've been using tusk top end gaskets in all my bikes and atv's over the past 2 years. Good quality and comes with everything you need for half the price of other brands. Don't hesitate to order any tusk products. I guarantee you won't be disappointed.

  • Tusk Clutch Spring Set

    Tusk Clutch Spring Set

    Rajiv in FL

    good for price

    I bought this to replace spring on my Rm, however these are shorter and are stiffer. Im not sure how well it performs since I recently installed it. It was fairly cheap so its no issue if I choose to not use it anymore.
