As the engine wears, performance will decrease. It is suggested to replace parts as needed
when the following symptoms are detected.
• Engine sound changes and easily overheats.
• Power has dropped.
• Idling is unstable and/or engine cuts out when idling.
In most cases, the bearings, piston & sleeve assembly, connecting rod and/or crankcase
have become worn. Check the parts carefully and replace as needed.
