Not sure about this bit though:
The remaining weak point of the motorcycle is cam chain tensioner (CCT) failure. The only good thing about this failure is that it rarely results in engine damage and simply requires the CCT to be replaced. Of the two tensioners, it is the front which is more likely to fail and it is, unfortunately, the more awkward of the two to replace. Replacement is comfortably within the capabilities of the competent home mechanic, but the valve timing must also be checked after CCT failure.
