This was just a free 1 hour talk at the local BMW dealership by a guy who does suspension setup at the local racetrack. Was really a means of promoting his business but I went in there knowing nothing so I had nothing to lose. The guy was certainly knowledgeable but was a poor public speaker so it was kind of boring. He spent most of the time going over various terminology and showing us all kinds of springs and forks and stuff (you can see it’s all fresh in my mind ). He probably mentioned oil viscosity but I cannot say for certain now. I do remember him saying temperature would affect your oil and he would have adjusted his forks before riding that day (was about the freezing mark). Don’t remember anything about triple trees.
All I plan on doing at this point is ensuring my preload is set correctly for my weight. Once I get that done I may play with the damping and see what difference that makes.
