everytime i make a turn left or right i feel like the bike is going to fish tail out from under me just wonerding if anyone else had this prob also in the pic of the shock the gold pc at the top of shock is very lose but the nuts on each side r tight thx for help

 

There's so many things that could be causing that I don't know where to start... Front and rear tire pressures right? Are the tires bald or " flat spot"? Are the rear wheel bearings bad? Is the swing arm pivot bearings bad or loose? I don't think I've ever seen a shock cause issues like your describing.

 

Perhaps you need to have the suspension set up for you & your riding style.
