Tried to replace my childhood frame from back in 1983 yesterday. FAIL !!! Once had a Hi Performance ATC90 with dads (local at the time) buddy Pete Fisher aka Powroll nutted-up 180cc monster. And to be honest as a kid wanted to my pants when they started it up. Someday one will return and NEVER to be sold ........ Guess I'am not over-it !!! Cheers to the dude who got it ......
