OK.. so i was finising all services with my KLX650R .. i have done all my bikes my self and NEVER HAD HAPPENED THIS: oil plug just crack...i did hear unusual sound..stop immediately.. start opening back plug and ..i have just end off that plug??? i am looking what happened.. ok it officially broken.. Checking can i make any cut to get maybe for screwrider or make reversed bolt pattern inside stuck bit.. i touch with my drill and ..plums goes to magnet inside engine! And i these diamond drils end so i was very careful because they cut like butter any metal.. SO anybody have ideas ????
