I recently adjusted the spring preload on my CBR919, 40mm front and rear, bike sag was 15mm. Front adjustment is on showing last grove and rear is on second last notch. Doesn't look like I can get any more that 35mm with these springs, are they shot? I guess I'm gonna need 25-30mm for then next track day. I am a 75kg rider with gear, ideal rider weight for stock springs is 73kg or 160lbs according to RaceTech.
I've done some touring perhaps the bagage weight has softened the springs!?
I also made the 17inch front wheel mod, do I need to compensate for the 1inch extra on the front by raise/lowering the rear/front.
