Wiseco PWR119101 Garage Buddy Complete Engine Rebuild Kit 48mm Standard Bore

The Wiseco PWR119101 Garage Buddy is a complete engine rebuild kit engineered for the 1991–1997 Kawasaki KX80, featuring a standard 48.00mm bore. This all-in-one rotating and reciprocating kit covers everything from the bottom end to the top end, eliminating the hassle of sourcing individual components from multiple suppliers.

At the heart of the kit is a Wiseco Standard Series forged piston — manufactured exclusively via a forging process using aerospace-grade aluminum. Compared to cast alternatives, forged pistons deliver superior strength, impact resistance, and durability under the demands of high-performance two-stroke motocross applications. The extra-lightweight piston design promotes instant throttle response, while computer-engineered skirt profiles minimize cylinder wall friction. Anti-detonation grooves and precision ring land diameters are designed to eliminate ring blow-by and maximize performance.

Kit Includes:

• Complete crankshaft and rod assembly — designed and inspected for durability
• OEM-quality main bearings
• All engine gaskets, seals, and O-rings
• Wiseco Standard Series forged piston kit (piston, ring(s), wrist pin, circlips)
• Small-end needle bearing (two-stroke application)
• Wiseco hour meter with mounting bracket and decal
• Assembly lube

Every component in the Garage Buddy kit is manufactured from premium materials and engineered to meet or exceed OEM specifications and tolerances. The included hour meter allows riders to monitor engine hours and stay ahead of critical service intervals. Made in the USA.
