First day on track this year, I felt front-end chattering in middle of steady-state corners. Only did it middle of long corners when I'm not on brakes or throttle. Talked to my coach/mentor about this. He bounced front-end up & down and said it was too "springy".
Turns out, I made mistake of rebuilding my forks over winter with 10w oil in attempt to get more front-end traction. Also zip-tie showed I'm 5mm away from using up all suspension-travel in front. So I replaced oil with 15w, turned up compression-damping a tiny bit, added 5mm more fork-oil than stock. Next time out, no more chattering and front-end feels firmly planted!!!
