Good To Know

Q: Is this kit suitable for bored-out cylinders? A: This kit is designed strictly for standard 49mm bores and will not work with oversized or bored cylinders.

Q: Do the piston rings require end-gap checking before assembly? A: Yes, checking the ring end-gap in the cylinder bore is a standard mechanical practice before finalizing installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
