Bob, here is my reply to an earlier request for a video telling how to remove the ECU. I am sure there might be some shortcuts, so anyone who has those, please feel free to edit or correct what I have outlined.
"I don't do much in the way of videos, but I will outline my procedure. First go buy some more of those micro towels like the Dr Beasly kit had. They were $2.49 a bag at Harbor Freight. Cover your front fender very well and maybe even tape one on for safe measure. I like wearing thin vinyl gloves and this helps keep sweat and grease down a bit when you are working on this finish. You will need a good assortment of metric allen wrenches, pretty sure you need a 6mm, a 5, 4.5, 4, and 3mm. If you don't have these you might as well stop and go get them now. I use the T handle ones and these are essential to have if you are going to work on the H2, don't even think about trying to use the all in one tool or the loose wrenches, it just takes too much time. I also use some 1/4 drive Snap On's for this and like to use a small 20 volt Dewalt impact for disassembly. You will also need a 10 mm socket. As I said in another thread, I like to lay out the fasteners in rows, in the order they come off and try to do it on each side of the bike. Put them on a shop rag, a board, a shelf, whatever, just try to organize them. If you will have it apart long, I try to replace as many fasteners as possible, to further minimize confusion.
Take the windshield off with its six or eight screws. Be careful not to scratch the windshield, if you use anything firmer than microfiber, you will scratch the windshield, I learned that the hard way. The windshield will pull back and off. The mirrors seem logical as the next step, but hold off until you can get to the wiring to remove them (learned this the hard way too).
Pull off the lower fairings on each side. There will be two black screws up top, three on the side, a large one going to the frame, one at the back and one at the very bottom of the radiator. When you pull the left side off, there will be two wiring connections to pop loose. On the right side you need to pull off the overflow hose. Pop them off and set them aside. Now pull the inner covers. They have four or five screws and when they are all loose, pop the cover off, it does have one snap fitting at the front, so give it a tug once you have all the screws out. Now you can see the turn signal wires, free those and remove the mirrors by removing the two black screws, turn the mirror to get access.
Okay, we getting close. There are two screws between the speedo and the tank to remove and two 10 mm bolts in front. With these out, make sure you have a towel on the fender, and pull the fairing forward. There is no need to disconnect the fuse holder or the headlights.
The ECU is under the throttle and brake master cylinder. It is bracketed it with about 5 screws and three brackets. This is a good time to take some pictures (I didn't, wish I had). Pull the three electrical connectors, no need to mark them, they only fit one space each. Now you are ready to mail it off to Don Guhl!
Hope this helps."
