When I replace the primary gasket on my 04 Road King Custom Sport I found an easy method for installing the gasket. This method will keep the gasket aligned perfectly and eliminate damage as well to the new gasket. In addition will keep the gasket in place or from falling off when intalling the primary cover.... Use the longest primary bolt and match at any hardware store and match size with 4 ea. shouldered bolts aprox. 3" long and cut off the heads and then file smooth.. Now use these bolts temporarily and thread them by hand at at top, right, left, right and bottom of case and simply slip new gasket over the bolts, Note: shoulder protects gasket and the primary cover. Now install the primary cover and intall the factory bolts as specified, remove the temporay bolts and replace with factory bolts. No more dropping the gasket perfect alignment and fool proof install every time. I have no more problems with primary gasket replacement. This method works on other HD model as well.
