At the risk of shame from my mistake, I put this out there to help others avoid my trouble. I noticed my rear tire had no cap on the valve stem the other day, so I got one out of my tool box and put it on. Next day on the highway I noticed the bike wouldn't move when I went to change lanes and realized my back tire was going flat. Once I was able to inspect it, I saw that the valve stem cap was deformed and saw where it was hitting the caliper. The stupid cap was about 2 or 3 millimeters too tall and this interference broke the stem. Just a word of caution to you fellow VFR owners!
