Sidestand Angle

The sidestand on my T140E has been "fixed" in the past. The bike leans over much more than it should. The tab has a big weld to the frame and the tab has also been bent out. (picture attached if I did it right.)

About what angle should the sidestand tab be relative to vertical or horizontal?

Thanks much!

Good luck getting an answer on this. I tried last winter when I was doing the frame on my '66 and I had folks try to help and post pictures and such, but it appears there is no hard answer regarding angle.

And I'll tell you that although it appears to pretty easy to measure the angle on that stand, it really is not. I happened to have a T140V that was fine and measured the angle of the straighted vertical leg with a machinist protractor and asked a few more here to do the same. I then set my bike up on wheels and clamped the lug in place, put the sidestand on and marked the frame. The weight of the engine does not cause the suspension to compress much at all so the bare frame was okay to use.

Go to my restoration thread, Rob's T120R restoration and you'll find info on this along with photos of my bike on the sidestand. I suspect I provided the measured angles of the bikes I measured as well.

Also do a search here for that thread I started last winter.

Your lug is obvioulsy something somebody made up from two pieces of steel and then welded them to what remained of the old lug. If they did not weld the two pieces together, they will slip relative to each other and you really only have the strenght of half of the lug thickness instead of the entire lug thickness.

I suggest that you straighten out the lug with head and get it to the angle you want. DON'T QUENCH IT!. Let it cool slowly. Then, I would MIG weld the seam between the two pieces, making a weld prep first for decent penetration, all the way around. You might even drill the hold bigger, weld it up and then redrill it to the right size as this will give you an added weld in the center of the lug.

Lastly, don't kick start the bike on the sidestand. That's what usually causes them to break.

regards,
Rob

A single piece of 1/2" flat would have been 4 times stronger,but welding them together will work too.
If you remove any nearby heat-vulnerable parts,it should be easy enough if you heat both pieces red at the bend.You could pull it back with a big spanner.Fit a piece of sheet-metal as a heat-shield between the engine and frame,to keep heat off the engine.

It looks as though if you pulled it back until the outer edges lined up,the angle would be about right.Somewhere between 35 and 40 degrees below horizontal should work OK.5 degrees only makes about 1" difference at the end of the stand.You can always bend the arm of the stand later,so it all looks good.

Even a plain arc-welder would be good enough to weld the two flats together.Completely disconnect the battery before you weld.

On one of my bikes, the angle is wrong, but the tab looks original (ie factory welded). I can see that the angle is way out compared to my other bike. Is this an easy job to fix?

Mine was like that when I bought my '77 T140V.

A local blacksmith heated and bent the lug while it was on the centre stand, offering up the side stand until it looked right.

I assume that your stand has moved?

I bought a chrome plated one, rather than plate mine, and found that the angle was way out. After a bit of filing on the new stand, the angle returned..

Si it might be a poor quality repro stand, rather than a misaligned bracket?

I've got five T140's to compare it with. It's definitely the angle of the tab. I'm glad to hear that it can easily be sorted in situ by a blacksmith.
