Stainless steel bolt kit would be a good start.
Yeah Just how long that Schit takes to change and fit Isn't worth it !
@Mullgs Clean it well and see what needs done Rubber brake hoses ? Time to get those changed!
Loom probably needs the rubber sheath stripped off and replaced with loom tape (Loosely not bound up tight! )
Fuel Lines Quick release ?? Change the Male ones as at this age the end can often just shear off letting the tank drain its contents
Alternator belt ? Ever changed ??
HES sensor wiring? Ever Checked or changed?
Subloom to Ignition switch Ever Checked or changed?
Cosmetics ? Under the fuel tank a good scrub and ACF 50 on all connections and I protect the underside of the tank with Black waxoyl and while you are there wire brush the wee pump flange bolts and
make them shine and be gentle and unscrew them and change the filter and internal hoses and anti seize those and write on the tank the miles / Date you changed the fuel filter
Spokes and Rims and that Stuff is a pain but worth it once done Then heat up some vaseline in a pot of boiling water and brush it on Wash it off after the next winter and it should still be shiny under the poop
AND if you decide the stainless kit make sure and use an ALLOY anti seize because copper ease "can" set up a 3 way reaction and make it real difficult to get back out later
