Specs At A Glance

Good To Know

Q: Does this cylinder need honing before installation? A: Most rebuilders recommend measuring the bore and honing as needed to match the new piston and rings, so follow the manufacturer service procedure for your 600 HO CFI.

Q: Can I replace one cylinder without touching the other? A: On a twin-cylinder 600 HO CFI, it is common practice to inspect and refresh both cylinders at the same time so compression stays balanced across the engine.

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