【SA39J】エンジンからカラカラ音がすると思ったらジョグの「例の場所」からだった【あるある】

This time, we repaired a Yamaha Jog SA39J. The noise was intermittent and very quiet, so if you listened carefully, you could only hear it. An engine has many moving and rubbing parts, so we had to check and inspect each one individually. This is because there's a chance that the problem is not in a single place. In the end, we found only one problem, but the essence of diagnostics can be summed up in the saying, "Slow and steady wins the race." This time, we'll show you how to identify and repair the abnormal noise while checking and inspecting various parts. Please subscribe to our channel and give us a high rating.
