This is my first post and also this past week I bought my first Trike! It is somewhat of a basket case, but it will be my summer project. First of all, my question...Where do I go about locating the serial number of this machine? The guy I bought it from says it is a 1986 Tri Moto 175 2 Stroke, but I want to make sure of what I have before starting locate some missing parts. Thanks in advance for any tips. Zman
