I seen this for sale. You have some changes to make for riding it off road.
Good advice above. I would add pulling the carb apart (easy enough) and see what you are working with. Needle clip postion, pilot and main jet numbers to at least know where you are at. Count your turns out on the air bleed also. Once the carb is off you definitely need to check those reeds out since it is easy also.
