Hi
I wondered if this was normal behavior but after all I don't believe that possible.When I put the side stand out, it just snaps back up again. To park the bike, I have to block it in the deployed position with my left foot, the slowly lean it to the left. As you can imagine leaning this beast to the left with only your right foot in contact with the ground is a scary operation and needs full concentration. I've only fallen once, and luckily someone saw and helped me lift the bike again straight away.
Is this a known problem? If so, what's the fix? Mine is an 86 K100. I believe later bikes had a clutch cable controlled stand.
-
This is normal behavior on 2V models which don't have the clutch assisted retract mechanism.
The result is the same, you don't drive away With the sidestand down.
Which model that have this or the other mechanism varies with the market/country.

My k75 does it, too, so you're not alone... Maybe i'm bigger or stronger but i have no real problem leaning it on the side stand. Other than the leanangle it takes that is, but that, too, is apparently normal. As my side and mainstand keep sagging further with age and wear i'm on the lookout for a k1100 set to replace them with though... Oh and according to many (me too) we should use the main stand primarily to avoid the smokescreen... But that's another story...

There are two different spring shackle designs - one causes the side stand to retract automatically when pressure is relieved (yours) and the other allows the side stand to lock into position (not yours).

Part #4 in the diagram above. The "not yours" shackle has a deeper cutout. Purchase the right one and you can fix this problem by substituting the old one with the new one.

Wow, I'm amazed. I've owned a lot of bikes and I've never seen a side stand like that before. I found the manual. It says to put the stand down while standing next to the bike. I find that harder to do than when sitting on it probably because I'm not tall enough. I like to have it leaning slightly when getting on and off.

Sounds like #4 will cure your problem then.

It's hard to do when fatigued after being in the saddle for hours regardless of height. It's a "safety" idea not suited for a top-heavy bike. Swap the part.

Like my 78 R100S.
I did not know it followed to the K-bikes as my 93 K75S has the clutch cable retraction.

Ive read from a couple members that the clutch cable retraction causes the cable to break more frequently?
While its a cool feature to have, I am thinking of removing the clutch cable part...
-
I personally keep mine on, only as a reminder that the side stand is deployed and not as a means to retract the sidestand. The latter, jjs, leads to premature cable breakage. I normally retract the sidestand before starting the bike, since I straddle it. In those rare cases where I forget, the excessive lever pull is a big clue for me. I then manually retract the stand with my foot. I view it as a non-intrusive safety feature.

Yup, agree that if properly adjusted it is very non-intrusive and can serve as an "oh yea" reminder.

How do you adjust the cable-operated side stand? It is a nice feature to have but my other rides do not have it, so no big thing if it doesn't retract easily (which mine doesn't).
Coincidently, my K75 Standard tipped over yesterday with me still sitting on it. I had just pulled into a parking spot, cut the engine--leaving the tranny in 1st and put the side stand down as usual. About the same time, a honey whipped in beside me and I was distracted from the dismount function. I still had my clutch lever pulled from cutting the engine, so when I put the side stand down with my foot, it immediately came back up and before I could react, the top heavy beast tipped over. Fortunately, I have engine guards so the only damage was my highway peg twisted but I was able to re position it with my grimy little hands. Oh, yeah, the woman was a looker!

Holycrap! The things some guys will do to attract the attention of hot chicks...
-
She didn't notice. Was talking on her phone the whole time.
-
As I said, I don't have the luxury of the clutch controlled side stand and absolute concentration is needed while blocking it with my left foot as I lean over. Once I start leaning, there's no going back. When it happened to me, there was no one except a garage attendant who saw me and ran to help get the beast off of me. I never thought about doing it on purpose when there's a nice looking woman though. Could be a good trick, I guess it all depends how you fall. You need to her to think "oh the poor guy" and not "what an a**"

You can easily fix the problem by deepening cutout on the shackle you have now (if you don't want to order a new part). Use a grinding bit on a Dremel to increase the depth of the cutout. It doesn't need much. Use the diagram above to get an idea of the final shape and approximate depth. The idea is to have the shackle bottom out against the sidestand pivot bolt later in its travel so that the springs are oversprung when the sidestand is fully extracted. This overspringing is what retains the sidestand once deployed.

I remember a Chris Harris video where he mentioned a specific distance for it to be adjusted but cannot find it now. Check out the technical library: http://www.motobrick.com/index.php/topic,2755.msg15712.html#msg15712 (http://www.motobrick.com/index.php/topic,2755.msg15712.html#msg15712)

Thanks for the link. I'll check that out tomorrow. I have a lot of slop in my side stand but don't know if the bearing is worn out or something else. It has plenty of grease on the bolt. Tightening the adjuster nut makes sense to increase the tension, as the rod is in effect being shortened.
I believe I have just the opposite problem of the original poster. His stand won't stay down, mine won't come up by pulling in the clutch lever every time.
