The modern Air Cooled bonnevilles have a design flaw for the footpegs. Loads of reports of them failing at the tack welded head bolt, the clevis bracket or the alloy casting at the pivot pin fork. The bolt failure is most typical. A local buddy of mine had his low mileage bonne fail that way, then happened again within 6 months of dealer. fitting replacement. It is 5/16th full threaded mild steel with the head tack welded to the clevis. Takes all the shearloading from rider. Fractures right att the joint point, across the bolt shaft threads. DIY upgrade is to knock out the tack head bolt, drill to next size and use a higher grade, shanked bolt with a couple of washers and nylok nuts.
Piece of mind!
