I assume you mean a Granite Peak...if you are..then I would no recommend it. I put a 2 stroke 80cc on mine but the Carb makes it a TIGHT fit...I am just as newbie as you if not more...so there MAY be more variables to it then what I know.
The Granite peak is a fine bike to motorize but the 4 stroke kit motors will not fit. The two stroke kits fit tight but well especially if you direct mount the front to the frame with a little machine work. I have some info by clicking my signature or you can always p.m. me for help.
