Product details
Description
The Boyesen WPK-07B Supercooler Black Water Pump Kit is an essential aftermarket cooling upgrade engineered to optimize your off-road motorcycle thermal management system. Crafted from high-grade investment cast aluminum with a durable black powder-coated finish, this complete cover and impeller combination is precision-designed to eliminate casting seams and restrictive sharp bends found in standard factory configurations.
By leveraging advanced hydrodynamic principles and a patented nautilus-style impeller, the system significantly improves fluid velocity and volume across all RPM ranges. This targeted enhancement prevents power loss caused by overheating, decreases internal system cavitation, and lowers core operating temperatures to safeguard your engine during demanding motocross or trail sessions.
Tailored specifically for precision fitment, it provides riders with reliable temperature control and extended mechanical longevity without requiring complex modifications.
How to use
- Drain the existing coolant system completely.
- Remove the stock water pump cover and factory impeller.
- Clean the mounting surface thoroughly and install the Boyesen Supercooler cover and patented nautilus impeller using the proper gasket or seal.
- Secure all mounting bolts to manufacturer recommended torque specifications, refill with high-quality coolant, and bleed the system of any trapped air before operating.
