I need help identifying this engine

[erectordale]

I think this is a ytm engine a 175 around 1981 . :wondering Does anybody know what this is ??? I've been told it say's 175cc on it this is the only pic I have now. Just tryingt to figure out what it is.

I am fairly sure it is a YT engine, so if it says 175 then it must be the YT175. There were few changes in the years, very few changes with the engines. Is that a 200x frame it is in?

[erectordale]

from what I can tell its a 82 r frame with 84 r forks

I guess I need to study up on my foot pegs then lol
