Most of us have experienced the wobble of the stock tires on grooved pavement. Well yesterday I was turning left onto a highway on ramp. I slowed to let a car coming the other way turn right on the same on-ramp. Instead of keeping in his right lane he swung into the left lane in front of me. This annoyed me a bit so I crossed to the right and went WOT. The on-ramp is grooved and with my rapidity and stock tires the FTR started to wobble into the beginning of a serious tank slapper. I eased off an it settled down. So be careful out there. Accelerating fast on grooves can unsettle the bike.
