Hey all I am new to the forums and just picked up my first Trail 70. I don't know a ton about the bike and was hoping some of you could help me with a few questions. First I have identified the frame vin as ct70-21xxx... which I beleive means it is a 73'? Is this correct? The next question I have is the engine vin reads ct70e-30...... What does this mean? Is the engine correct to the frame? Any help would be greatly appreciated!
