Got this bike with 42k on it. Ran like a champ for about 5k. Then, started getting an intermitant problem, loud clicking (almost like the "thunk" when you shift), loss of power, and then it would just go away for a while. I was afraid to take it out on a trip. H D mechanics couldnĀ“t diagnose, threw away $100s on no fix. Finally found out roller bearing was going out and one roller was getting a flat spot. Anyone else had this on a similar bike? VERY irritating that certified mechanics couldnĀ“t diagnose.
