Wiseco PWR178-100 Garage Buddy Complete Engine Rebuild Kit 47mm Two-Stroke

The Wiseco PWR178-100 Garage Buddy Complete Engine Rebuild Kit is an all-in-one solution for a full two-stroke engine restoration, delivering both top-end and bottom-end components in a single, convenient package. Engineered for the serious home mechanic or race team, this kit eliminates the guesswork of sourcing individual parts and ensures every critical component meets Wiseco's exacting quality standards.

At the heart of this kit is a complete crankshaft assembly featuring precision-machined crank webs for maximum strength and durability. The connecting rod is copper-plated, heat-treated, and shot-peened to remove residual stress for a smooth, reliable power delivery. The included Wiseco forged piston (47.00mm bore) offers stock compression with superior reliability and longevity over OEM cast pistons, thanks to the proven benefits of the forging process.

Kit Includes:

• Complete crankshaft assembly with OEM-quality main bearings
• Wiseco forged piston kit — piston, ring(s), wrist pin, and circlips
• Small-end bearing (two-stroke application)
• Complete top-end and bottom-end gasket kits (all gaskets, seals, and O-rings)
• Hour meter with mounting bracket, decal, and assembly lube

The included hour meter allows you to track maintenance intervals from day one of your fresh rebuild, and the Garage Buddy-specific decal identifies your engine as a Wiseco rebuild — a requirement for the kit's 90-day / 10-hour warranty against manufacturer defects. With everything boxed under one part number, this kit is the fastest, most reliable path to getting back on the track.
