Added Murph's wedges, and replaced my worn out PR2's with new ones today on my '08. This was my first time using the Harbor Frieght tire changer with the No mar bar. All went well with no problems. I'm very happy that I no longer have to pay someone to do it! This will pay for itself in short order. I also changed out the batteries in the TPMS Sensors since the front had quit working. I didn't realize just how sucky the bike was handling until I put the new tires on and with the wedges, the bike feels awesome! Now to do an oil change this weekend and I'll be all set.
