I am having problems with the forks pattering on my KX500 supermoto.When i am braking in a straight line into a corner everything is ok even into a tight hairpin from high speed.The problem happens when i am banked over in the corner and trying to carry speed.I was also having problems braking into corners but i have fixed that by changing to 10wt oil and preloading the springs so i have 1" of sag.Would it be best if i fitted heavier springs and if so how much more than std which is 0.39kg.Any advice would be very welcome
