Maybe you were dreaming......
IF it had holes in the fins that sounds like the motor out of that one sold on ebay back about 4 months back. The guy had 3 bikes in the listing, obviously Tom mcpeek bought it and those guys over there busted it up for parts as they were talking bout doing that.
They paid i think $700 for the whole bike so $900 for just the donk is a bit ritch ? And by the time you got it here that would end up over $1500. not really worth it heh
