Really works!!!

Tim in NV – Machine this part was bought for: 2012 YAMAHA WR450F

Comments On Apr 29, 2013:Before installing the bike would operate at 210-215 degrees F, after installing it runs at 170. I really doubted a new impeller would lower temps much but it absolutely works.

It really works - good cooling is an engine saver!

JOHNNY in OK – Machine this part was bought for: 2007 HONDA CRF450R

Comments On Feb 01, 2013:I bought this for my 07 crf450r honda and have yet to install, but i can give a reveiw since i also had the same one on my 02 model of the virtually same bike. I was less experienced back then and needed everything i could get to help cool my bike until i could get faster and have more air hitting the rads like was intended. I pretty much mastered riding dirtbikes in general now whether it be 2 or 4 strokes and can tell you this to anyone who is considering buying one of these: it's not how fast you are in races such as harescrambles, it's about how fast the guy who is in front of you that won't give way..............and that's when i count on all the little upgrades like this to help keep my bike running better, paired with a high pressure radiator cap to reduce overheating spillage.

A MUST HAVE FOR TRAIL RIDING

SCOTT in PA

Comments On Aug 22, 2012:I DO A LOT OF TRAIL RIDING AND MY BIKE OVERHEATED A LOT. I WAS ALWAYS LOOSING ANTIFREEZE AND I USE ENGINE ICE. AFTER I PUT THE BOYESEN PUMP ON I NOTICED IMMEDIATE IMPROVEMENT. DOES NOT OVERHEAT ANY MORE. I ALSO NOTICED BETTER CLUTCH PERFORMANCE. IT USED TO FADE A LOT. NOT ANYMORE. IT KEEPS THE SAME CLUTCH PULL NO MATTER HOW HOT IT IS AND NO MATTER WHAT I AM DOING OR HOW LONG I AM DOING IT.

A YZ450F or CR450F Must Have!

SHAUN in UT

Comments On May 01, 2012:If you ride sand dunes or race this is a must. I have put this on my CRF450 and my YZ450F because they both boiled over in the Sand with Paddle Tires. You have to drain the coolant to do this easy install. Make sure you change the Coolant to that Blue Liquid Ice coolant for dropping temps even more. Flush the radiator first though with Distilled water. Bike runs a lot cooler and never has boiled over in Desert Races and Sand with this water pump.

Boyesen supercooler

JAMES in UT

Comments On Mar 25, 2012:This SuperCooler has improved coolant flow helping to keep engine cooler. Bigger than stock blades on impeller. Bigger than stock basin (housing) allowing more flow.
