I have a aeon cobra 220 and the oil cap has a hole in it and oil is coming out anyone know where i can get a new one or one that that is the same fit ?

 

First try googling the on-line sellers who advertise Aeon Cobra spares. Next try those who sell new Aeon bikes. If that fails, the engine may be a clone of something. Doesn't look like a Honda, but could be a copy of a Suzuki/Kawasaki, etc.
