I've had a pretty weird experience in the past year and I'm looking for someone to give me some advice. For the previous oil service I noticed that I'm losing oil, not a lot, but enough to need to top it off. It wasn't smoking and I didn't notice any leaks, so i was confused, but I still rode the bike. I did an oil service and now for the past 2k miles roughly it hasn't lost a drop of oil. Anyone has any ideas why?
