I'm in the process of putting my '74 together and have come to the point where I want to mount the sidestand. The bolt I have, 7/16' I believe, fits the mounting hole in the frame properly, but is too large in diameter for the hole in the sidestand. The bike was in pieces when I got it so don't have the original bolt, but I have no reason to believe the sidestand is not the original one....what am I missing here? Thanks...

This caught me out briefly when I was in exactly the same position - what you're missing is the spacer which fits inside the stand and enables the bolt to clamp up without binding the stand.

Thanks....I have the spacer....the problem is that the bolt is too large for the hole in the sidestand, but just right for the hole in the frame. I can drill it out, but don't understand why it is too small....I guess it's possible that a previous owner resleeved the hole in the stand, it's now approximately 3/8 inch, but why not the hole in the stand.....

No, nut goes on other side.
Lucky you that it's just a hole size problem. The mounting lug welded to the frame tube on my '74 Roadster is definitely bent up. The bike leans too far over when the side stand is deployed. Don't want to mess with heating up lug/frame tube which could weaken the frame tube in the heat-affected zone and make things worse. I guess I'll just have to use the center stand exclusively, but I can live with that.

No, no, no... take a hint from our Trumpy buddy DPO!

I thought about having a wedge with bolt hole machined that would fit under the existing bracket to restore the correct angle with frame tube, but was afraid that once the bracket/tube has already started to rotate, that unintended consequences could occur, such as a kinked/sheared frame tube.

2 options in my head for you and an easy fix IMO.
1.. Fabricate 2 "tapered washers" so the stand is at your required angle, you will av to think about that abit ... or,
2.. Take the stand off, get the oxy out, heat it up red hot, and bend/straighten it back to original angle adjacent/below/near to the pivot point... It has bent over time !!!!!!
Dont get all out of shape in your head and remember it is a side stand. In reality it could easily be substituted with a piece of 12-16mm round bar.. the original stand will be made of cast steel, not cast iron and you could bend it into a "U" shape if you require.. Just dont think about using water to cool it.... Hope this helps.

Bill,
Easy problem to solve; the stand is soft steel and bends over time. With the sidestand extended, shim up the tip with wood strips until the bike sits at the attitude that pleases you. Measure the shim height (mine took 1.5" to set the bike at the proper attitude). Using the center stand or a paddock stand, secure the bike, remove the sidestand, and mount the sidestand in a vise, clamping the mounting tab. Rig up a pointer to mark the tip position; you'll be wanting to bend the stand, and this will be your measurement jig. Remove the stand and place it in a press (I have a cheap HF bench-top 8-ton press that worked fine), find the bend, and press it out. Remove the stand, measure, and repeat until the tip moves to your measurement. The whole thing is a 1-hour job. No need for heat. You'll be good for another 40 years. I got the basic technique from Mexico Mike a few years ago (thanks, Mike) on this board.

Rick, so you're saying in your case that the side stand itself is where all the bending occurred? I see a slight bend in the arm, maybe a couple degrees, at he tab that connects the spring. Not enough to make much difference. Looking at the mounting bracket on the frame tube, it has a radiused bend curving up. I also note that the frame tube is not round at the top weld of the bracket. Looks like it is slightly crushed from the bracket bending up. So I don't thing bending the arm itself would do the trick. I think the frame tube could crush even more if I tried that fix. Just being cautious here. Thanks for the info though.
