Just replaced my front tire on my 2007 flhtc with champion kit and am having a vibration problem. the bike has no vibration until it gets over 65mph and then it just vibrates more the faster you go and i did not have this problem with the old tire. i am going back to the Harley dealer to see what they can do for me but when i called they said it could be a lot of things and they will have to check them out. the tire they installed was a Dunlop wide whitewall 402 and the one i replaced was a Avon. I did watch them balance the tire from the service window and noticed when they spun it to check the balance they only gave it a real slow spin. Has anybody got any suggestions what the problems could be if it is not the tire even though that is where i think it is but many of you know more than i do and i am always learning from this great site.
