Skorpion Sidestand woes

Anyone come up with a solution or a replacement to the Skorpion sidestand? Mine has eaten slightly into the stop and also had lateral movement. There is not enough meat on the mounting block to cut a bigger hole to fit a larger diameter bush either...

TIA

You can replace the Skorpion sidestand with the more robust one from an MZ 125 SM with a bit of modification. You can see details here: http://mzskorpion.mybb3.org/sidestand-t113.html

two things here;
- remove the sidestand and weld a blob (or have welded) on the left sie of the U-bracket where it is now worn sofar the stand goes too far forward - that is the problem, isn't it? Happen with most which have the first version stand. It the blob is too big just file (grind) to fit.

- Replace the Bolt (axle) with one which is not threaded in the axle part of the length and bush the frame bracket. It is not too skimpy to bush with say a 1mm wall thickness. You will probably habe to turn (have turned) and very good for this would be a discarded valve guide (ask any good motor shop) because such bronze is the idea bearing material for this. Then, shim the U-bracket so the the stand is a nearly tight fit.

Then keep is greased.
I personally have a slightly modified Ducati sidestand fitted to the Skorpion frame.

ike all Ducati stands, this one snaps up by itself; there is no sidestand switch to cause problems.

Thanks Bill,
"oart of the length and bush the frame bracket" lost me though. Can you reframe please? :)

how lost?

Simply a longer bolt so that it has a portion of unthreaded shaft. If you are turning (having turned) anything, you can make a speciall one-off bolt from a standard 3/8" Allenhead with an unthreaded shaft, turning the 3/8" shaft down to fit the enlarged hole tightly (adjustable reamer, certianly available in the machine shop if you go this far) and then cutting a new thread behind the shaft. Original is 8mm which could present a problem in the States, but even 1/4-20 woud be enuf to hold the bolt. Come to think of it, just straight-forward reaming the U-braket and frame to take a 3/8" bolt would more than suffice and alleviate the necessity of a bushing.
If you wan to go super-sexy tho, the bronze bushing reamed into the frame so that is a snug but turnable fit would be the best bet. Make that busing slightly shorter than the inside measurement of the U-bracket. THe 8mm bolt can remain as is; thighten that up to the ends of the bushing which will be the part that turns in the hole in the frame. Since the U-Bracket is a poor fit, you should fit a disc spring (Tellerfeder):

or as many as necessary. Of course in this case the center hole of the spring will have to be larger than the bushing. If the Bolt is the axle, only as large as the bolt, of course.

One should space out the side stand with these disc springs from the beginning. That would probably take care of the wobble and wear to start with so that such repairs are not necessary.
