I have vibration at about 80mph and it increases the faster I go above 80. I notice the vibration in the my hands on the grips and the mirrors do become blurred as well. Below 80 the bike runs smoother. My Touring is all stock. I thought when I changed out my front tire it might smooth out but it didn't. Maybe I have one of the problems mentioned on this thread. I have had problems with starting the bike at times, it seems like I don't get enough power to the starter to turn it over enough. I bought a new battery with increased amps but it didn't help. A couple of days ago I tried to start the bike and didn't think it was going to start but it finally did. I checked the battery and it didn't show any volts then in showed 14 volts and then none again, the volts came and went, I checked other batteries I have and the tester was consistent. I think I must have a electrical problem, and maybe that could be causing the vibration. At times I have clicking noise when I crank the motor. I think I might need a new relay. Can I go to auto parts store to get a new relay or will I need to get one from Triumph dealer. Thanks for any impute.
