I have a oil leak which for some reason seems to be from a screw at the top of the alternator cover. Its a rr4 Blade, just had a recent Oil and Filter Change but before this it had fallen over from a standing position where the crash bung took a light impact as I had hold of the bike all the way down. The left hand fairing as a of fine oil spray and obviously is coursing smoke from the affected area. The crash bung is attached to the effected cover with 2 screws and spacers. Why would I get a oil leak from their when its supposed to be oil free?
