i have a 2007 kx 85 dirt bike i want to change the spark plug and air filter but i don't no if it's to soon or not please help thank you
How often do i change the air filter and spark plug on my kx 85dirt bike?
that all depends on how much it's used. if you race, you should change, (the spark plug at least) every 4 races or so. if you don't, use it much i'd say about every two and a half months. i'm sure you can figure out the median to those two ends.
