I'm selling my 80cc motorized bike used it to get to and from work then stopped working one day (think its electrical) so for that reason I'm selling it cheap from what I've read online seems like an easy fix will leak gas while its sitting if you don't close the valve other than that it doesn't leak while riding it.
Great gas saver gets 60+ miles to the gallon (half gallon tank on bike)
Any questions call Kevin
