Good To Know

Q: Does this kit include the necessary gaskets? A: Yes, the kit includes a full gasket set for the top end, including base gasket, head gasket, and intake/exhaust gaskets.

Q: Can this overbore kit be used on a standard 1986-1987 ATC200X cylinder? A: This kit is designed for a .040 over bore, meaning the cylinder must be bored to 66mm; it will not fit a stock bore without machining.

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