Welcome.:thumbsup: An ambitious undertaking but hey, there are lost treasures everywhere still so it's not impossible by any means. I found what many big bike enthusiasts consider the Holy Grail of trail bikes, a 1966 Hot Shot purpose built race bike with 230cc 2 stroke power from a snowmobile and that's how it came. Said to be one of ten known and the best of the ten I found it in a barn in Shawnee Oklahoma. I looked at a vague ad that read two vintage scooters and I always look because scooters bring good $. This is what they were:
The green one was also made by the same company for the same big trailbike outfit (Bearkat) for their racing program and both were raced extensively.
So good luck with your quest, you and many of us are all looking for the same bikes it would seem and there is no shortage of guys with the means to overpay if that's what it takes. I am not one of those guys however, just a poor country boy barely makin' it here in Oklahoma so I'm no big player. I have to pass up many good vintage parts all the time here:laugh:
