    Waterpump upgrade for WR400

    Had cooling issues with the stock pump around city traffic. Ordered this kit and only took 10 minutes to install. And now temps sit at 60C while riding on street. 80C while offroading in low gear thick stuff, and 90C in traffic. Before it was over 100C before i shut it off. Great product and very well made.

    Didn't help cool my YZ426f.

    No difference in cooling on my YZ426f. I idle around 250 deg C both before and after this was installed.
