Wiseco PWR149101 Garage Buddy Complete Engine Rebuild Kit 66mm Standard Bore

The Wiseco PWR149101 Garage Buddy Complete Engine Rebuild Kit delivers everything needed for a full top and bottom end engine rebuild in a single box. Engineered for the serious motocross rider, this all-inclusive kit eliminates the hassle of sourcing individual components — from the crankshaft to the piston, gaskets, and even an hour meter to track critical service intervals.

At the heart of the kit is a Wiseco standard series forged piston at 66mm standard bore with 11.7:1 compression ratio. Unlike cast pistons, Wiseco's aerospace-grade aluminum forgings compress the material's molecules to increase density and align grain flow, resulting in superior impact resistance, fatigue strength, and longevity under demanding race conditions. Wiseco crankshafts are fully designed by in-house engineers, with all assembled dimensions, clearances, materials, and specifications determined to exceed OEM quality.

Kit Includes:

• Wiseco standard series forged piston kit (piston, ring(s), wrist pin, and clips)
• Crankshaft assembly
• OEM-quality main bearings
• Small end / top end bearing
• Cam chain
• Complete engine gasket, seal, and O-ring set
• Wiseco hour meter with mounting bracket and decal

Every component is manufactured from premium materials and engineered to meet or exceed OEM specifications and tolerances. In-house dyno testing ensures that each design delivers proven performance and reliability across a wide range of operating conditions. The included hour meter allows riders to track engine hours and stay on top of scheduled maintenance intervals, helping extend engine life.

The Wiseco Garage Buddy kit is a cost-effective, time-saving solution for complete engine rebuilds — giving you OEM-quality results with the added durability and performance benefits of Wiseco's forging process. Made in the USA.
