pic 1 the case is broken so you cant bolt the starter in, that's why it is blocked off.pic 2 the green and yellow wires are the head lights, the square with green, brown, yellow and blue and triangle with red black and black is the handle bar switch the 4 prong goes to the key switch and the black looks like it might be coil ground. pic 3 is the cdi and those plug into the wires fro the stator. pic 4 the 2 plugs with the zip tie the one on the right goes in the back spot where it looks like something is missing, the unplugged one is for the rectifier, the starter solenoid is supposed to be where the zip tie is. pic 5 black wire is from the solenoid to the starter, red wire hooks to the main battery cable not sure if it is upstream or down from the fuse, the fuse is on the bottom of the solenoid you don't have, not sure about baby blue. the case of the motor is junk, cant be repaired so you cant put the starter back in. looks like you have most everything electrical but that cdi is a guess there is no test for it you just have to eliminate everything else. it looks like at a minimum you will need a rectifier, key switch, and handle bar multi switch. i hate to see a machine scrapped but i think this one is on the edge. the 87s are a tough sell because of the cdi, you can by 89 and newer fairly nice for 1200 and restored for 1500 all day long. i am not sure it is worth fighting the 87 electronics that harness looked rough and at best you end up with the 87 stuff. unless you can find a super cheap parts bike i dont see you getting her on the road for under 500 and when i restored mine i had another 400 in general wear/maintenance parts ie brakes, bushing bearings to make it safe. i know the machines inside out and it takes me about 40 hours to do a resto. so if you got it free you might break even and in the end it is still a stiff rough riding warrior. if the cdi is good should part out on ebay 300 - 400 if you put the time into disassembling and listing the stuff. i have seen the cdi for as much as 300 alone. so if you love it fix it if it is just another bike to you i would part it. hope this helps.
