Hi, I am in a similar position as freedomfighter. I am trying to find out what year my DT175 is. I do know that the engine has been replaced, so it does not match the frame. Unfortunately. The frame number is 2K4-011686 X. The 2 stroke oil resivour is on the left side behind the side panel. The battery is on the right hand side below the air box. I have been told it is a 1979.
Please can someone help me?
Regards
Jason
