Just wondering if anybody has had problems with the oil sight tube? I'm about to fit the Baja Designs oil sight tube onto my XR650R. (Also ftting Scotts damper with dipstick-mounted post so the sight tube is kinda neccessary). I've heard some reports of thees sight tubes actiually leaking oil, and also that they are not very accurate at measuring oil levels (apparently oil gets stuck in the tube???). But on the other hand, a lot of people seem to be using them. Any feedback before I start drilling?
