This is my first bike ever! I received from my dads friend's friend. It has been sitting for a few years and to my knowledge all it needs to run is a clutch lever and perch. I'm sure there is a ton of maintnenece that it needs also. What kind of maintnenece can i perform myself and what must i have and experienced person do? I am pretty mechanically inclined and have built up 2 strokes from scratch for smaller applications such as go-peds. What year it is? Also I realize it is way to much bike for a newb such as myself, but its all I got and free is free so all first time riding tips are much appreciated. Its dirty in the pictures becuase it was to cold to clean the bike.
