750 K2 Strip & Rebuild - help please
Sesman:
One for Mr Honda. Can’t imagine why they would be needed though.

It's a tensile load path (pulling the bolts principally into stretch) that is holding onto the hydraulic action of braking application. They have enough torque on the bolt when assembled that they aren't going to come undone in use.
The bolt is effectively stretched to a force greater than any spring washer could assist in this application.
Sesman:
And they are not subject to vibration, at least of a harmonic amplitude that would justify further treatment. Now if it were an engine mounting bolt that might be a different matter.
Lobo:
Thought pls on what’s happening here with the instruments- it’s doing my head in. AFAIK all components original, including new OEM clock rubber surrounds. With the rubber locators seated within each instrument slot and upper bridge slot, the Rev counter sits a few degrees to the left, and the speedo even more degrees out to the right. If I twist them to straight ahead obviously those rubber locators cease to locate / do their jobs.
What am I missing? (Tbh this problem had always been there - I just shaved the previous rubbers…)
Oddjob:
Mounting bracket bent? Possible old crash damage never fixed.
