BOYESEN SCORPA SY250F SUPERCOOLER WATERPUMP UPGRADE KITThis supercooloer water pump kit is a huge upgrade for the Scorpa SY250F Originally designed for the Yamaha YZ WR engine it means that it also fits the Yamaha engine fitted to the Scorpa also. We run one of these on our own bike and have noticed a massive improvement in the performance of the machine as the engine runs at a cooler and more consistent temperature. This is because this kit increases the water flow through the engine jacket dramatically.
