I did not expect to open a can of worms but I will explain the difference.
Self Retracting Side Stand [Early K bikes, 2v]
Early Ks, 83, 84 had a side stand that needed the weight of the bike on it to stay down. If for some reason the weight of the bike was removed it immediately retracted. My introduction to this absolutely foul arrangement was when I went to buy my RT, from a member on the forum here.
I wanted to get off the bike, my normal practice from the K100LT I was riding for 3 years was to flick down the sidestand and then lean the bike on to it, making sure it was fully extended. But it would not stay down so I could not get off the darn bike.
Back to seller and I said this needs to be sorted or I can't buy the bike. At that stage I was happy with everything. Anyway investigation revealed a boomerang plate attached to the side stand spring that got caught by the bolt causing it to retract. Cut the bolt so the plate passes over it and all is good, sidestand stays down. I rode the bike home, a 2 hour ride on a sunny Friday evening.
Many years alter, buying my first RS, same feature but a hacksaw blade cured it in exactly the same way. Seller wished he had known that trick....
Side Stand Retractor later 2v Ks.
Now for my K100LT. It has a mechanism attached to the clutch cable that will retract the side stand. In theory it is fine but if you use be prepared to keep breaking clutch cables. But the resistance as you pull the clutch to start the bike does remind you to take up the side stand so as far as I am concerned its a great idea.
Side Stand Switch [16v and K1100 and some 2v police bikes.
This is located under the gear box and is actuated by the side stand being retracted.
This can go faulty so if you have a 16v K or a K1100 put the bike on centre stand and go in and have a look for this by using the side stand, you will see the metal tab.
Occasionally this goes faulty and you get a no start. As in the fuel pump will not prime. Most of the time a few wriggles will sort it. It is easy to make a by pass. It is worth finding where it connects to the loom and making the by pass and popping it in the duck tail for when the inevitable happens.
I have been told this is on some ex police bikes. My K100LT was ex police but did not have it. Otherwise, its only on 4v/K1/K1100
Feel free to point out any errors, but as it's Patrick's Day here all complaints will be directed to the Timbuctu office.
