Getting ready to mount new front and rear tires and have some preventative maintainance questions. The bike is a 2007 Road King Classic with 43,000 miles. I have no issues with wheel balance, handling, loose spokes etc. but ......... 1. Since I have the wheels off should I replace both wheel bearings? They are the original bearings. 2. Again no handling issues or loose spokes but is it wise to have the spokes trued due to mileage?
