Roadside bodging (first and second gears not selecting)

[Fazerider]

To complete this long-running tale I should add that the problem came back after a few weeks. :rolleyes
I extracted the shift arm again and even before measuring could see that the tab had unbent itself enough to collide with the selector drum pins again. The tension caused by the cooled weld had relieved itself by cracking the inside of the bend.
I did attempt to weld the inside of the corner, but a stick welder isn't the best tool for an awkward job like that and my skills certainly weren't up to it either. I discarded the ruined mess I'd made and tried grinding the top of the tab down a bit on another second-hand shaft.






This appears to be the best solution. The tab is still long enough to act as the stay for the claw return spring but is short enough to pass over the tips of the pins on the selector drum without hitting them. The metal is incredibly hard, a cobalt steel hacksaw made no headway through it, grinding it down was effective, though it takes a while to clean up afterwards. The pic should make things clear, I ground the tab down to about 8mm measuring from the tip to the back of the plate.
