Here is a list of what my bike has had go wrong since new in 2003.
Tires needed replacing after 10,000 miles.
Oil had to be changed a few times
Had to adjust the clutch
Damn thing keeps using gas
Sorry to be a wise ass, but its post like this that make it sound like every dog has a problem. That totally isn't the case from what I've seen up here. I feel for the few that had issues with new bikes, but for the most part, these are great bikes. I've had friends with new harley's that totally sucked ass, and the dealer was not too kind to them, when it was clearly Harleys fault. So its not just Big Dog.
These bikes are like a high performance sports car, and they need to be touched all the time. Do I have to tighten stuff up, yes. But so far, my bike has been a dream from when the first owner bought it in 2003 and put 10,000 miles on it, only having to do routine maintenance to it. I've got almost 3,000 on the same bike, and have only adjusted the clutch and put gas in it so far. Not bad for a custom bike.
Best news is, guys up here are excellent in helping you get your Dog up and running if you do have an issue.
