Just a quick update...
I was on the track again today, and I think I've been able to solve the problem!
I increased the rear compression with 3 clicks harder, and softened the preload on the rear by 2 clicks. No more wiggling around for me, ye! I pushed it harder and harder out of the problematic corner, and at one point was hitting 160-180km/h coming out of the turn before I had to slow for the next. It stayed its line, and didnt move from it.
I had more confidence in the bike, and was able to start concentrating on trun-in points, apexes and opening the throttle earlier out of the corners, and better body positioning.
I dropped my laptimes by 7 seconds, from my previous trackday laptimes. Definatly a huge improvement.
Thanks for all the info and help guys. Much appreciated
