Greetings all. I have a 1980 GS550L. Is there supposed to be a drain hole in the oil filter cover, usually sealed with a bolt and gasket, but that can be removed for draining? I look at my bike's oil filter cover and there is an obvious place where it should be, and its expected presence seems to be generally confirmed by my Haynes and Clymer manuals. It's like the casting was made and everything was ready for a drain bolt, but the hole was never drilled through. Any opinions about whether this was on purpose (e.g., some engineer decided that spraying the exhaust or front tire with used oil was a bad idea) or do you think something else happened (like 50 of these came off the assembly line before someone discovered they didn't look right but used them anyway)? I can still drain oil from the bottom of my engine, it's just harder to get at and a drain bolt at the front of the bike seems more convenient. The oil cover looks like it is aluminum, and although it would be easy to drill out, could this be a bad idea and just making a new place for a leak to eventually happen? I'd appreciate any thoughts about whether this is something I should or should not attempt, and if so, pointers and suggestions to keep me from messing up would be appreciated.
