By the way, to remove that valve stem seals was quite a pain without proper tool, due to quite deep wells. I did not need such tool in my other projects, but now, sitting in Malaysia, purchased such puller. Since there is another brick in the queue, will see how it works.

Shopping in Malaysia was not bad.
Got the tool for the springs.
However, if center stand assembly removed completely to work on bench, this tool is not needed. :laughing4-giggles:

Original rear master cylinder was terrible, as was shown before. Found original used part, but it was not pumping either. 177381
So took an overhaul kit, now all ok.

Brembo forks.

What is correct oil volume????

I drained 200 ml.
In Haynes says 420 when dry
In Maintenance manual says 0.330 for K75.

The 420ml figure is for Showa forks from 1991 on when the oil is drained completely.
The attached chart from IBMWR is widely accepted and shows the figures for Showas, sport forks and Brembos. Brembos are identified by an imprint on the slider.

to avoid having many keys (individual per lock), decided to replace lock insert from original lock to the new one.
this is original lock for low seat.

Unfortunately, these inserts are not interchangeable, they are of different construction of the actuator (not very seen on this photo)

Left is high seat lock, right is low seat lock.

today is one month since parts for engine were sent by supplier in Germany. And delivery date is still not know, as per tracking they are in the middle of nowhere.... When this worldwide craziness already finish?
However, sometimes long waiting time is good. Thus, i was looking yesterday through the pictures of disassembly, and suddenly realized that i installed output shaft wrongly.  boohoo Original mark almost lost its paint mark.

Since engine is open, the situation was immediately rectified.
