I own a Harley Davidson motorcycle and recently needed to have it fixed as well. To be honest, what I dislike most about motorcycles is the process of repairing them, because it is really very difficult and in addition I am not very good at it, so I decided to simplify my task and turned to the Harley Davidson wiki for help
Here I was able to find a lot of information about what could be wrong with my motorcycle and how to fix it.
