Details

    Overheating, cavitation, and poor coolant circulation can mean excessive wear and damage to components. Use the Boyesen Supercooler Water Pump Cover and Impeller Kit and you’ll get superior cooling that keeps your bike running at its best.

    By increasing the coolant passage size, creating a high-flow impeller, and smoothing all interior surfaces to reduce friction, the Supercooler pumps out more coolant at a faster rate than your stock water pump. The Boyesen cover looks great but it keeps things simple too since it has the same footprint as your stock unit. No need for any special gaskets or fitment. Just bolt the Supercooler up like it’s stock.

    With high-revving, hard-working dirt bike and ATV engines, temperature management is key to keeping your machine running well. Make sure you have the parts to keep it that way with the Boyesen Supercooler Water Pump Cover and Impeller Kit.

    Specs:
  • High efficiency water pump and cover for increased engine cooling
  • Investment cast from aluminum alloy for lightweight strength
  • Same footprint as stock parts for bolt-on installation without special gaskets or fitment
  • High-flow impeller moves more coolant than stock parts
  • Less cavitation on impeller means better efficiency and longer impeller shaft life
  • Higher flow rate with larger diameter passages and low-friction internal surfaces

Solid product but mostly for looks
The boysen cooler is a great looking addition to your bike. As far as performance it has a slightly bulkier impeller which claims to increase cooling efficiency by up to 5% under EXTREME conditions. I would say 90% of the people buying this product will only benefit from the looks of it. I am one of those people and this is the second one I've bought for my bikes.

Bought 2 of these
I put one on my CRF150R for harescrambles and worked great! I definitely noticed that my bike did not get overheated like it did with the stock water pump. So I bought one for my KX250F. Only issue I had was that the stock O-ring for the hose that goes into the water pump was not big enough and when I thought I was done and started filling my radiator, the fluid was leaking out. So I just went to the hardware store and bought a rubber washer/gasket to fit. Now works great!

Quite a bit bigger impeller than the stock one on my klx. Seems to keep the temp down. Highly recommend !!

It's a quality part
But it didn't make my 450 run any cooler even with engine ice in the gnarly stuff. It's still overheating constantly

What is your opinion on this pump vs. radiator fan?..Both would be overkill I believe.
Michael A on Apr 22, 2017
BEST ANSWER: I have both the fan and the Boyesen pump. I installed the fan first after my KTM 350 was boiling over all the time on tight trails. (it's ridiculous that ktm ever sold this bike without a fan) The fan helped but it would still sometimes overheat so I got this water pump. It made the situation even better and now the bike never overheats but the fan will still kick on sometimes, which tells me that it's good to have the fan there. I also use engine ice in the radiator.
Is it difficult to install? Do you have to take the engine apart to put that c-clip around the impeller?
Lanc B on Jan 1, 2017
BEST ANSWER: If you own a Kawi, its easy... the impeller unbolts... just be careful holding the impeller, it's sharp... I think the hondas have a 10mm nut built into the impeller which makes it easier... no c-clip that I am aware of. Hope this helps.
Does this product come with a gasket?
Arron V on Jan 23, 2017
BEST ANSWER: This product indeed comes with a gasket. I would recommend changing to a high performance coolant as well if you havent done so already. You will have noticable gains in power and your machine will run noticabley cooler.
Does it come with gasket?
A shopper on Oct 7, 2016
BEST ANSWER: Been a while, but I believe you use the original. But it's beautifully made and everything fits perfectly.
