Did I just void my warranty by changing the oil myself?
There is no authorized service centre nearby and the hacks that do service scooters want $95 Canadian dollars per hour plus costs to do this. I did have fun doing my first oil change before 1000 km. I put some vinyl tubing on the end of a plastic funnel to access the oil reservoir. There's no oil filter on a 50 cc scooter. There is a tubular screen inside the drain. It had some metal filings on it so I cleaned them off with paint thinner and let it dry before reinstalling it.
