Built for Yamaha YFS200 Blaster Engines
This Blaster bottom-end rebuild kit combines the major crankshaft-related components normally replaced during an engine overhaul. Having the bearings, seals, gaskets and critical locking hardware together helps eliminate delays caused by missing small parts during assembly.
Koyo main bearings provide proven quality for the crankshaft installation. New seals and gaskets help protect against air leaks and lubricant leaks, while the included lock washers, crank key and snap rings replace commonly worn or damaged engine hardware.
Why Choose a Rebuilt OEM Blaster Crankshaft?
The factory Yamaha crankshaft provides an excellent foundation for a stock or performance Yamaha YFS200 engine. A properly rebuilt OEM crankshaft maintains the correct factory dimensions and fit while replacing worn internal components.
This kit is a strong choice for riders restoring a stock Blaster, repairing a damaged bottom end or building a dependable recreational engine.
Professional engine assembly and correct bearing, seal and crankshaft installation are recommended. Always inspect the crankcases, transmission, balance shaft and related components before completing your rebuild.
