Trying to figure make model motor size ect...

 

Im not 100% sure but it looks like it may be a 150cc. My recommendation is to look around on the motor for a model number, it will be stamped on the case somewhere. Hopefully, that helps good luck!

 

Almost certain it is a "Minarelli" two stroke. These are mostly 90cc but were available from 50cc to 150cc Polaris used them for a while and Apache until recently, may still do, plus a host of other Chinese/Taiwanese makers, mostly in the early 2000s, before the Honda cub clone four stroke engine became dominant. There will be an engine number, and the prefix should tell you the capacity if you google it.

 

The # on the case is JA50 ☆081030☆

 

Oh dear, that maker hasn't played by the rules, the 50 bit could mean 50cc but usually a Minarelli engine prefix would be something like E40QMB.
