My Fatboy Lo had a weird sound the second week after I picked up the bike, had a loose compensator but no vibration they kept it overnight then it was ok.
But it did have a bad vibration when accelerating but the said it was normal for a Harley which is a load of shit, I said I know the harley will never be as smooth as my sportbike but they insisted it was normal. Anyway after a while I had to change the rear tyre and found that the rear wheel bearing was stuffed they fixed it under warranty. Never had so much trouble with a new bike before. Wow the price you pay for the Harley you would think you were going to get some quality.
Would never buy another Harley again.
