I recently have been having issus with the handling of my 2011 GSXR/750. It all started (in a galaxy far far away), not really, but after the local paving company put down the slurry/tar covering on the pavement in my neighborhood. I would take my bike out and the suspension (unadjusted stock) would handle great, I could lean it perfectly. Since the tarring in the street the feeling now is the front end wants to slip when dipping into corners. Another sensation is the bike "seeking" for grip. Its almost like it skates from right to left.
I have replaced the stock BT-016 tires that come on the Suzuki bikes with Michelin Power 2CT. Air pressures are checked and checked rigorously.
Looking for some suggestions; possibly a steering dmapner issue?
