I have a 96 Trophy 1200 and recently did the coils, I'm not sure if its exactly the same but should be very close. I'll give you a quick rundown and hope it is of some value.
The job is easy, I can do in about 30 mins usually. Just make sure you have the tools. Each coil is held on by torx (star shaped, size 20 I think???) headed screws so make sure you have some ready. Get a few pieces of scrap wood about 4 inches long and a stick about 12-18 inches long. You can use the wood to help prop up the tank so you don't have to totally disassemble everything. You'll also need a small ratchet with sockets and a few allen wrenches.
The way I do it:
1. Unlock the handlebars so they move freely. Put bike on center stand (if possible). Remove the seat
2. Take off the two screws under the seat that hold the rear tailpiece to the frame.
3. Carefully (Very carefully) pop out the front of the tailpiece (toward the center of the bike where they meet the tank). Each side is supported by 3 plastic pins that fit inside rubber grommets. They break easily if not careful.
4. Wedge a piece of wood between the tailpiece and the airbox to help spread the plastics outward about 3" each.(enough to use tools in there)
5. Under the tank where it meets the seat, you will see a black bracket that mounts the tank to the frame. Use a ratchet and take off the six horizontal screws (3 on each side) that are there.
6. Put a towel over the battery to prevent the tank from touching the terminals. Very carefully, slide the tank back towards the battery (about 3 inches). You will feel the front of the tank unhook
7. Carefully grab the front of the tank and lift upwards and back. Use a thin stick or piece of wood to prop up the front of the tank. (as if you're propping up a box with a stick to capture an animal). You should make sure that your tank is propped up safely so you can walk away and have room to work underneath it.
8. You will see the coils are mounted right there to the frame with torx bolts. Unclip one wire plug on the old coils. Take a look at the tip on the old coil and see if it is threaded or smooth (like a spark plug) It should be threaded. The Nology coils come with smooth pin adapters installed. Take them off with pliers. Make sure you put each wire in the proper place on the Nology coils because they have a firing order to each cylinder. Then you can take off the old coils and bolt the new ones in.
9. After the coils are in, remove the stick and lower the front of the tank. Then slide the tank forward and you will feel it lock in place.
10. If your bike has a fuel cutoff switch on the left side, make sure that the fuel hoses and the air vent hose to the petcock, did not kink. If any of the 3 hoses are kinked, the bike will not start because it won't get the right fuel/air to the carb.
11. Put back in the 6 screws for the tank mount.
12. Remove the wood blocks and put the plastic pins back in for the tail section. Also put in the 2 screws that hold the plastic to frame.
13. Put on the seat and start it up. Should start pretty fast because these coils are alot stronger than stock Gills brand.
Hopefully it all goes smoothly for you. Let us know how it goes and Good luck to you.
