Installation Notes

• Break-in: Vary engine speeds and avoid sustained full-throttle for the first 100 miles to allow rings to seat properly.
• Pre-lube: Lightly oil piston rings and cylinder walls with 2-stroke oil before assembly to prevent dry starts.
• While you're in there: Inspect crank seals and reed valves for cracking or hardening — much easier to replace with the cylinder removed.
