Stopped my bike from overheating

Works great on 2008 CRF250R. The bike is older and one of the issues was radiator fluid overheating and coming out o f the overflow tube. I use Engine Ice to help but this new water pump did the trick. I also got the OEM bearing and washers for the water pump from Motosport while i was at it. I used to ride in Glamis a lot and this is the first thing that anyone who rides in extremely hot climates says to do to a bike.

Works great for keeping the motor cool

Awesome product, but sometimes it’s a little difficult to install due to the tight tolerances of the impeller shaft

Easy bolt on performance

Definitely a wise investment to keep your bike running as cool as possible!!! Motor temps are between 7-12 degrees cooler after a 15 minute Moto. Installation was extremely easy won't have a bike without one ever again!!!!

Best mod for trail riding

Since installing the pump I haven't noticed the FE501 Getting too hot in the slow tight tech stuff. Best mod for a big bore four-stroke!

Awesome!

I bought this pump for my two Yamaha’s and now my ktm. I would highly recommend this product to anyone. It definitely helps out here in the hot summers we have in the Carolinas.

A: That is a good question. I have always used the Boyesen cover with the Boyesen pump impeller because it's a kit and they were probably designed to work more efficiently together.
