Hello all, yesterday I changed my oil and filter. When I drained my oil little to none came out of the drain in the frame. Usually there is at least half a quart in there. The amount in the bucket came up to the level it normally does after all have been drained. This brings us to my question. I haven't been able to ride for a week and a half due to weather. Does all of the oil drain down into the engine after the bike sits for a while?? I thought it stayed in the frame until the engine was running. Is this normal, or do I need to check something out?
