Good To Know
Q: Do these rings fit standard bore Arctic Cat 650 V2? A: No, they are .020 over size; use only with cylinders bored to 80.5mm.
Q: Can I install these rings without honing? A: Proper ring seating requires a cross-hatch finish on the cylinder walls, so honing is recommended before installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
