Yamaha V star 1100 clutch adjustment 

You should back the screw up then tighten the screw until you actually feel it hit something then back a quarter turn. Please edit your video

What's the electric wire that plugs in to clutch handle?

And the screw is more than likely JIS (JAPANESE INDUSTRIAL STANDARD), not Phillips. A good chance why it stripped.

What did you torque your clutch pressure place to on the backside? The 6x bolts that hold the string part

loosen bolt. unscrew to the left until loose but not completely out. then tighten to the right until you hit a snug point. then loosen to the left a qaurter turn. hold srcew @ that point and tightn the bolt. your video is backwards and not helping shit
