Evidently I have a bad case of excessive throttle use on my ride. Just took it down for it last service before winter sets in and the bike has 7000 miles on it and the rear tire is very close to the wear bars. Wore right out in 7000 miles. I am also very meticulous on keeping my air pressure right where its suppose to be so it wasn't a low pressure air problem. Just excessive acceleration, probably some right wrist trouble I think. Oh well it will have a new rear tire in the spring and see how long that one lasts.
