Does anyone out there know how to change the oil filter on a 1980 suzuki gs750l?

just got the bike and need to change it pretty bad.. so any help would be huge. thanks.Does anyone out there know how to change the oil filter on a 1980 suzuki gs750l?on the gs550 there was a circle cover on the front of the engine. i'd check there, it might be the same. take that off and the filter is inside. its spring loaded, so don't drop the cover in your used oil or something
