I changed the windscreen with a taller one ( 8cm taller from OTR ). On the first ride I went into some serious wobbling somewhere around 155km/h ( gps indicated )... I thought wind was causing it and tried later again in a more protected area - again the same... everything else is pretty much the same on the bike ( tires in pretty much same shape and not underinflated, suspension setup same, load same ) as other times when I didn't had any issues running long time at full throttle... Any of you experienced that with a taller screen?
