I engaged in a discussion about this on the weekend, but can’t find it so I’ll start another discussion. The sidestand on my ‘76 has always been “wobbly” and the bike leans over way too far for my liking when on the stand. At home I usually put a piece of wood under the foot of the stand to reduce the lean. I took the stand apart and the stand and bolt are in good shape. The problem is the tab for the stand that’s welded onto the frame has an enlarged hole. The stand bolt is 10mm and the frame hole is closer to 11mm. I want to tighten things up and have two basic options:
1. Weld the frame hole up and redrill to 10mm - or cut off the old tab and replace it with a new one of proper dimensions.
2. Drill the stand and frame to accept a 12mm shoulder bolt.
I’m leaning towards option 2 and here’s why. To weld in the hole on the frame is a bit tricky especially for a rookie welder like me. It will also be challenging to redrill the hole in the correct spot, square to the tab. Also not comfortable with cutting the tab off. With option 2, I only need to open the hole in the frame about 1mm. This should be easier than drilling a new hole. It will also require drilling the kickstand, but I can do that in the drill press and if I mess it up, re-welding and drilling will be much easier off the bike.
The ‘76 it has a unique, one year only stand. It uses a 10mm shoulder bolt with a 16mm shank and the threaded part is 8mm. Fortunately I can buy a 12mm shoulder bolt with a 16mm shank. The threaded section is 10mm. So all I need to do is enlarge 2 holes in the stand. One to 12mm and the other to 10mm.
Before I hack up the stand, does what I’m doing make sense or should I be trying to weld up the hole? I guess option 3 could be a bushing in the frame hole?
Note the new shoulder bolt has a 25mm shoulder, I need to buy the 16mm one.
