I have a 2007 HD Softail Deluxe, I have not been on it much in past couple of months, tried it last week and it would´nt start, I connected cables to my car, lights and all were on nice and bright but would just wind and not kick over. Could this be bad gas in the injectors, how could I remedy this without taking to Harley and having to sign my 401k over to them? appreciate any suggestions.
