Hi Guys, I am wondering how to properly check the oil level on my GS500. Here are many questions I have about that "simple" check: 1. How do I need to position the bike? I know it needs to be levelled. Does that mean I can use the side-stand and/or the center-stand? 2. Does the engine needs to be cold/warm/hot? If warm, how long should I let the engine run before I check? How does it affect the level? (is it lower/higher when cold?) 3. When checking, shall I screw the dipstick in or just let it rest unscrewed? (I think I have read I should NOT screw it in but correct me if I'm wrong - does that depend on bike models?). Thanks for any help!
