All parts of the bike are original. It is a 1974 K3 (low) numbers matching frame/engine ct70-23000456/ct70e-000434 built in May 1973, but it had been on fire/in a fire at one time. I used all the parts that were restorable. The only hard parts that were replaced were the headlight ears (which still had to be repaired!) and the turn signals (which I did not have). Otherwise, I used mostly NOS/OEM parts, or reproductions. The engine and all its components are original including the piston. The engine has been rebuilt with new gaskets, seals, and rings. The head was disassembled and cleaned. Valves were hand-lapped and the motor has strong compression. Otherwise, just lots of polishing, cleaning, and re-painting. I should have the chrome next week. I will also get to recover the seat using the original repaired seat pan! I hope to ride it sometime in the next two weeks! (but, I'll take some pics first for all you Trail 70 nuts!)
Cheers!
