Break-In Note: Proper “break-in” is essential. Vary your engine speeds and avoid sustained full-throttle operation for the first 100 miles to allow the rings to seat perfectly against the cylinder wall.

Installation Tip: Before installing, lightly oil the piston rings and cylinder walls with 2-stroke oil. This prevents “dry starts” and protects the new surfaces during the first revolutions.

Pro Tip: While the top end is off, this is the perfect time to inspect your crank seals and reed valves. If you see any signs of cracking or hardening, replace them now—it’s much easier while the cylinder is removed.
