Installation and engine checks
Use the verified cold-engine procedure, clean the plug wells and avoid cross-threading or over-torque. Confirm connector or cap fit and clearance. After installation, check starting, idle, misfire indicators, diagnostic codes and plug condition; stop and diagnose abnormal operation before riding.
