Petre, Check out voleurs thread - KLE 05 with accessories. You will see photo guide to fitting centre stand. It is easy to fit, the only problem I encountered was putting both springs on but it can be done. Side stand remains in place. It may take you a few attempts to master putting bike on centre stand as it is not located on balance point of bike, situated slightly to rear.
I have raising kit on my bike. Easy to remove tie rods (dog bones) and replace. Greatest difficulty I had was removing bolt close to exhaust. I got around the problem by lying bike on ground, just a leverage thing.
Same principal to lower rear of bike
