You’re going crazy soon….

Heyho, the following problem has been with me for a long time and it brings me more and more into perplexity.. 1. Folding the front suspension So as soon as I am on a worse road (Pflaster or similar ) a hard flapping on the passenger side. I thought then will probably be the damper has been changed to at 60,000. FOH did everything well and nice but each after about 200km the same goes off again so the question to someone who already gets a Similar test had what that could be? Pendulum support, bearing or something? 2.Temparature display of the cooling water. I recently noticed that the display rises to 92 -97° after short rides (10km) and always fluctuates in the 2° range. Sometimes it also happens that the display hits to the stop. If I then slightly knock against the disc it goes down again and behaves “to some extent” calmly. All other displays (speed, tank etc.) run without problems.What could it be? Mass FOH said that the cooler itself was fine, so I think only the thermostat or the water pump would remain or not? Thanks already in advance for the answers =) mfg
