My sons 125cc coolster is leaking major oil. I don't know where it's coming from but when I park the Atv in the garage the next couple of days there is a decent sized oil spot about 8inches in diameter. It been leaking for a while and it won't stop. Any ideas???

 

Look all over the motor. Check the oil drain plug and all gasket areas to find out where it is leaking from. My guess is the oil plug. If it is, then replace it.
