11. TROUBLESHOOTING
11-
Symptom: HIGH ENGINE OPERATING TEMPERATURE
1. Check if cooling system shows any failure (see COOLING SYSTEM).
System is leaking. Repair and/or replace damaged part(s).
2. Check function of lubrication system (see LUBRICATION SYSTEM).
Lubrication is not working properly. Repair and/or replace damaged part(s).
3. Check condition and heat range of spark plugs.
Melted spark plug tip or inadequate heat range. Replace.
4. Check air leakage on engine intake.
Leakage causes overheating. Replace/repair damaged part(s).
5. Check air inlet and outlet of the CVT cover.
Air circulation is clogged (overheating).
Clean air circulation from contamination.
