I just put some new Kenda 760's on my XR650L, and went and did a 150 mile dual sport ride yesterday; 75 miles of which were some of the roughest trails I've ridden in my 23 years of dirt biking. Long story short, the extremely rocky terrain caused a partial chunking of my central section in a row of knobs. It's about 65% still connected, but has what appears to be a fairly deep tear. The tire has less than 500 miles on it, and I really don't want to scrap it since the tread is still good. I was thinking if I got some sort of tire glue, I could possibly save the section and not have to immediately replace the tire. Any suggestions as to what kind of glue to use to try and repair the knob?
