レストアしたエンジンの１０年後の確認してみてCB750FB

This time, it was a malfunction, so I just had to replace the broken tensioner, but I was planning to remove the carbon thoroughly, do a valve leak test, and fix only the bad parts, but since I was there, I decided to redo it at the same time. As for consumables, I replaced the valve stem seal, removed the carbon from the valve, and tried to grind the valve. If you want to ride it for a long time and take good care of it, you should do these things and you will be able to ride it for a long time, but with the rising cost of living, the reality is that the cost of parts is amazing, and since it's a bike that was manufactured 40 years ago, it goes without saying that the number of discontinued parts is increasing. This time, I had some parts that I usually had in stock, so I was glad that the work went smoothly.
