any help on these would be ok? The green one was my first bike ever had a 2/1/2 hp briggs my dad put on it off a potato sprayer. I was 8 years old when i got it. The parts for most are in other parts of the buildings, I never rode the red one my garndfather got it at a fle market when i was 10. The falcon slowster I rode for a long time till my one of my older brothers that was about 13 at the time tried to move the engine with a hammer to get the chain tight, busted the case, the neighbor was machinist welder fixed the case. I never put it backtogether , i got the heath kit after that, i was around 12 i could not pull start it verry good at the time could not keep up with my brothers riding the back roads and trails on it. so i stepped up to a BORED AND DOMED PISTON 1981 XR 80 AT AGE 13, THAT THING would run 75mph on the black top. I run it till the crank bearings went out. i was KIND of hill climber back then climing the left over hills the worlds biggest coal shovels left here in ohio , thats what i was keeping up with my OLDEST brother for, hill climing.
