I realized that my belt tension is not in spec. Almost 20kg too much.
Question: Is it necessary to put the zero on a lifting ramp so that the rear tire is without ground connection? Or can i just adjust the belt tension as described in the manual without a lifting ramp?
(The manual is not mentioning a lifting ramp, however the manual is known for not beiing very precise for the maintenance work (e.g. if changing headlight bulb, it does not say how to get to the "back of the lamp")
My concern is if i do it without a lifting ramp, probably the rear tire gets some "track-angle" if fastened again.
Thx for you help.
