Hello, so I just bought a 03 klx300r for a smokin deal. It’s got a Bill blue carb and new tires which are worth already more than I paid for the bike since it has an oil leak at the valve cover. Well I decided to pull off the valve cover to see what was going on... and well please look at the pictures. This is such a garbage job I can’t believe anyone could ruin this so bad. There was jb weld everywhere and I pulled the heli coil out. Please see how much material has been shaved off on. So please help me here, what are my options? Can I just drill deeper, tap in some threads or can I fill it all with weld? Any option is appreciated. Thank you
