After adjustment is is advised to turn the engine by hand a few times, set it to tdc again, and only then, check clearance again Nice video nonetheless
Y400Sm one of them got rounded, so I decided to replace all of them on the exhaust side. But be careful if you replace those bolts. Their lenght are not the same. The ones on the cam chain side are 45mm long, the two on the opposite side are only 40mm. Don’t mix them up.
