This has occurred to me as well, and it’s entirely possible that it’s a left-turn thing. Also nmK12’s suggestion that road camber might cause this to happen.I'm with the tire wear side of things. Left side does wear more than the right for some people. But, if you look at the Factory DVD there is a section I've seen in past searches that deals with not messing with the factory setting of some bushings in the head steering area that you work on while removing the front wheel carrier. They obviously are centering adjustments. I think any serious work in this area needs to be done by one of the few MC frame shops or someone who has done this before. Maybe there is a dealer shop qualified. My theory on left side wear is left turns are longer and people tend to take them harder & faster because you can see where your going. Of course this is not the case in the UK.
I have a hard time believing it's significant. I believe the camber of the road would cause more wear than the longer left turns.... no?I see you live in Texas so your riding in the US. This is function of the radius of a circle. Left turns take the longer path therefore there is more wear. Road camber may also play a small part but put simply its distance.
Ok I get it now.
