I have rebulid my Honda XR 600 R for last 2 years, 95% parts are new, includng new ohlins shock and new ( old but i have found in a shop new) 1992 cardrige syste forks.
I have also Scott steering stabilizer.
Today i went first time for a road ride. Above 100 km /h ( 60 ml) bike sarts to wobble, from right to left, like a snake.
What may be a problem? All stuff is new , is wrong suspension set up?, bad preasure in a tires?What else?
