Have not bothered reading his other threads or posts, but if the sump is a problem then it should have been brought up by the Yamaha engineers.
I did watch most of the video, it seemed all the bikes had their shortcomings and IMO for the money, simple things like the sump should not be one, nor should the BMW have final drive failures, and the KTM should not have fuel pump and water pump issues.
For that matter neither should the damn clutch basket, better than a GS? I do not know, I bought the Tenere over the GS do to supposed reliability, probably in reality they are closer to the same than many want to admit, I do not know but I do enjoy the Tenere so it is what it is
