I know evos are notorious for leaks, but i have a nasty leak coming from the forward head where the banjo bolt of my carb crossover is screwed in. Ive tried tightening the bolt in hopes the leak would stop but no sucess. I have a 80' evo with an S&S carb. The leak occurs while riding and at a stand still. Any ideas on what i can do to eleminate this problem? Oil gets all over my hard bags. Thanks in advance.
