I have about 4500 miles on my classic now. The only issue I have is an annoying squeak when going over bumps or when getting on or off the bike. When I took the bike in for its service, I told the technician to solve this issue. When I picked up the bike, I assumed that the issue was fixed but low and behold when I arrived home, there was that annoying sqweak again. Has anyone been experiencing this? The problem seemed to surface after washing it a few times. I do know the squeak is coming from the rear end of the bike. Feedback?
