Rebuild your Yamaha Blaster top end with 66mm OEM Yamaha Blaster cylinder kit properly sized 66mm cylinder kit. This kit provides the essential components needed to replace a worn or damaged Blaster cylinder while maintaining the dependable fit and construction of a genuine Yamaha cylinder.
The OEM cylinder is professionally sleeved and finished to a 66mm bore. This makes the kit an excellent option for Blaster owners who want to return an engine to the original 66mm bore size instead of using an oversized cylinder or an aftermarket cast cylinder.

Proper machining supports piston life, ring sealing, compression and reliable engine performance.

OEM Cylinder With a 66mm Bore
The Yamaha Blaster was originally designed with a 66mm bore. Returning the engine to this size provides a stock-displacement foundation suitable for trail riding, recreational riding and dependable engine rebuilds.
Unlike an inexpensive aftermarket cylinder kit, this package begins with an OEM Yamaha cylinder. The cylinder is professionally sleeved and machined for the included Pro-X piston, providing a high-quality alternative for engines with worn, damaged or previously overbored cylinders.
Pro-X Piston Kit
The included Pro-X piston is a quality replacement for a Yamaha Blaster top-end rebuild. Matching the piston to the finished cylinder bore helps establish the correct running clearance and reduces the guesswork involved in purchasing separate top-end components.
The kit also includes the top-end bearing and OEM gaskets needed during assembly. New cylinder studs and nuts provide fresh mounting hardware for installing the cylinder and head.
