Troubleshooting an Engine Noise

I developed a new engine noise after a high speed run on my 2004 Yamaha Grizzly 660. I take you step by step through my process of troubleshooting and how to isolate the cause of the noise, and assess the damage.

I also demonstrate how to use a mechanics stethoscope, check for loose valves, check spark plug color for ignition issues, how to check valve timing, and several other common issues while we looked for the issue.

In our case the problem was piston slap due to excessive wear at the wrist pin. I show the damage caused, and the parts I will need to replace.
