Despite my replacing the pivots, the problem of the indentations in the frame where the stand impacts it allows the centre stand to go too far forward, making it very heavy to use and rendering the bike less stable on the stand. Without taking the bike apart does anyone have any suggestions for a cunning bodge to solve this problem?
Well you asked for a bodge…

Could the indentations be filled with weld and ground back? Might help improve the integrity of the frame in that area too.

I'd worry about the effect of a weld on the tube, so I might start with the first suggestion, (or go to the gym).Thanks.

The frame has pads welded onto thebottom tubes where the stand stop lugs touch the frame. It would be possible to weld on new pads (they appear to be about 16 gauge (approx 1 1/2" x 1") and are shaped to the tube profile).
The other option would be to build up the lugs to compensate - this could be done with stand removed (but does involve the hassle of removing the stand. However, this wouldn't stop the original problem and the frame tubes may continue to deform.
The other thing to check is if the stand pivot holes have become extremely oval - this could negate the effect of your new pivots.

True confessions time. What I did many years ago was to remove the petrol tank and the battery, drain the oil tank and tip the beast upside down and weld patches onto the frame where the indentations were. It worked and still works to this day. Gordon.

I fully agree with this one having done it myself as well, the only cautionary word I would add is that the lower frame rails tend to be bowed upwards as well, and welding the patches on can make this worse, I would gas weld it and put plenty of heat into the surrounding area so that it cools slowly.
Incidentally, the frame I repaired was a 1957 one, and did not have the strengthening plates on it that the later ones do.
Good luck!

Just my luck, my Dommi is 1957. Can't complain, it is a great bike apart from the vibration.

welding is the only answer I welded my frame and ground it back then welded a patch of cut out tube were the stand meets the frame .as I had the frame striped of its paint at the time and then fitted the stand the engine plates with no paint on and turned the frame over to get the right place to weld the patches on . and that this point any other welding needed too be done can take place too.

Well you asked for a bodge. Try putting some pieces of sheet metal packing twixt stand and frame to get the right thickness of packing. Then shape pieces of packing the correct thickness to fit the frame and epoxy them in place.
