Well I bought a CZ 125 from the states, the whole deal cost me $3500, when I finely got it home, I desided not to restore the rolling frame, I tried to sell it as a whole bike, but no interest, a couple of friends told me to part it out, I ended up selling the complete roller
for less than $2000, I still have the engine which has been rebuilt, I have relisted the engine on ebay over 4-5 times, and it all cost. so the engine can sit. I will never part out a good bike ever again.
