2017 Ktm 125sx

I have a 2017 ktm 125, bought this bike about a month ago after not riding for 9 years thinking I’d want a less powerful bike, realized I’d rather have a 250. Bike had a new top and bottom end rebuild on it when I purchased it. Since then I’ve ridden the bike 9 times, put in a new air filter, cleaned it after every ride, as well as changed the gear oil after every 3 rides.
