I had a patch/plug installed last week at a Honda shop. Every other place I called that sounded like they would do it, refused when I told them what kind of bike it was.
Might regret saying this, but I believe the decision to repair a bike tire is based on individual circumstance. Many people won't re-use a used piston, go back with the old rings, main & rod bearings, pan gasket or head gasket. Maybe I've been lucky, but I've had nothing but good luck re-using speed parts that were still good. Point is, most people would throw something away because they don't know any better or don't care. It's easier to throw money at a situation than to think it through. I'm 1000 miles away from getting new skins for the front and back. I decided that if I kept the bike under 75 MPH it would be okay. I'm 200 miles into that decision as of today.
With that said, I would probably not repair a new tire. My bike is too much fun to limit the speed for the life of the tire. My own situation was different with it having so little left on it.
Like I said, it based on circumstance. I would not tell someone to arbitrarily throw something away. There is a ton of that mentality in car racing. I made a good living for awhile on Ebay selling parts that people were ready to throw in the trash.
Don't bash me too hard please. I'm making an honest statement I believe to be true.
