I am looking at the top of the frame tube, just behind the steering head, and there is a 14mm bolt where I would assume the oil fill and dipstick should be. Or am I looking in the wrong place? But when I remove the bolt there is no dipstick. I just bought this bike, and now that I'm thinking about it there is an aftermarket product (which I don't know what it is) connected to that bolt. I guess the previous owner removed the stock screw on dealy with dipstick and replaced it with a bolt and left the dipstick out. Here are pictures of what I'm talking about: What is the "Scotts" device at the top? What are my options to have a dipstick? I would like to be able to check my oil level as it is hot as hell here (105 today) and don't want to be running low on oil. Noobie says thanks.
