How do you check the oil level accurately after a change or any other time with out a stand. When I look at the site glass with the bike upright its hard to see it with out looking from a slightly high angle. I am not sure from my view point if I am seeing the level accurately. I feel I should be down further like on my knees to see it right but I don't feel comfortable trying to hold the bike perfectly upright like that. Just wondering if there is a technique to it. Maybe I'm being overly cautious since this is my first bike.
