Bike was running fine, all fluids good. Valves started ticking LOUD and temp light came on at the same time. Let it cool completely, same when re-start next day. Ideas? '99 VN1500G1 Nomad, 24K miles.

Would look at thermostat and/ or water pump

Overheating can be caused by many conditions. Did you just do any modifications or maintenance on the bike and then this happened? Overheating will cause valve train noise because the oil is starting to break down and thin from overheating. The temperature light could come on when cold if the temperature sensor is defective. The temperature sensor and fan sensor are located at the bottom of the radiator. Make sure the connections are secure. Since it overheated would change oil and filter, coolant, and thermostat with new O ring. If the radiator cap looks old, replace it too. While the fuel tank is off would also check any coolant, fuel, and vacuum hoses that might need replacing along with a visual check of other components that you don’t normally see with the tank installed. Use the proper coolant and oil. Procedures to check various components is in the manual. For some reason in the manual’s Table of Contents, pages 88 thru 107 are omitted which is the cooling system section. The pages are there, they are just missing in the Table of Contents. I posted three links below. The first takes you to the cooling section (page 89) and the second takes you to the Troubleshooting page about overheating. The third link takes you to a parts illustration of the cooling system. Are you doing this repair yourself? It is a bit of labor but not that difficult. Go for it. You will learn more about your ride. If you have any difficulty understanding anything, post back. We would be glad to help you.

Thanks! I don't think it's overheating, could be wrong. Will check all above. The temp light comes on immediately on start even when cold, and there's a lot of engine noise...both cans.

Hey Steve, Checking back to see how you made out.
Thanks for asking. I think the water pump went out. Looks like it will be cheaper to find a new motor than do a complete teardown. DammitMan strikes again.
