i thought about it a lot. I did actually had the thread that describes it, i did follow it, till step 4 or 5 saying remove bevel gear box. and not beeing native i thought it talks about the real gear box, well and then i just did stop to follow the recipe and ended up where i did end up.
lessons learned: read the whole recipe before you start, not just while you are doing it.
yup the seal got malformed by the kardan, had to bend it back, but it is seems tight.
regarding swing arm: yes one should not do it.
i did use belts, there was force on it, still hope that compared with the force of two people on bike at 140 and shock bottomed it was in say 'greenish' range
speedo was a cable issue
now i need to check why bike started to refuse starting when engine cold. seems like started during the shock incident but cant image how that should correlate.
lets read the errors
