    I don't usually post much on here cause I find most answers to my questions just by searching. But, this worked out really well for me and it seems to be a bugger for some, so I thought I'd share it.
    First of all, as has been mentioned before, the relay bracket that sits on top of the right frame side beside the right coil, has to go. Throw a shop towel down to catch all the bits (also so you don't melt things on your bike) and grind that bad boy off. Leave a little lump of weld so you don't cut into the frame and screw it up. Sand it all down, prime it, paint it.
    The perfect fit for me on these coils with my 650 frame was 3/4" plated corner brackets or "L" brackets. The holes are already there and they fit the M6 bolts perfectly. One end goes to the original coil bracket the other end sits on top of the new coil and lines up with the outside hole. Make sure the back of each corner bracket lines up closest to the frame on both sides. This works on both ends of the coil and everything lines up nicely. The other good thing about 3/4" brackets is the new coils don't hang much lower than the originals.
    Back to the relay bracket you took off. That now goes back on the left side of the frame under the tubing. This time a little further down the bike away from the left coil. Bad news, of course it has to be welded back on! Do it or find someone. has to happen. Before you do that and after you mock up the new coils, mock up the new position of the relay bracket (w/ relays on it) as well so you get a decent fit.
    Things you will need:
    -4-3/4" corner brackets
    -2 M6 or M5 x 20mm bolts with lock nuts and nuts. These are for the front end of the coil with the terminal screws for wiring. Short bolts so you can access the screws when its time to wire.
    -2 M6 or M5 x 25mm bolts with lock nuts and nuts for the back end of the coil.
    -This is up to you but, because I turned the backs of the corner brackets towards the inside of the frame, I didn't need such long "original" M6 coil bolts. I don't remember the length I bought. lol. Still M6 but shorter. Or use the originals and they stick out a bit. Up to you.
    That's pretty much it. All the "materials" should cost you less than $5 bucks at your local hardware store. Put it all on, tighten everything up, wire the old wires into the new coils, slap in your new spark plug wires and boots, put it back onto the bike and you're good to go.
    Any questions just ask.
    No. I didn't take any photos sorry.

    Forgot to mention, you will need to peel off the tape around where your relay wires come out of the wire harness. Pull down the wires to get more length for the new position of your relays and re-tape with electrical tape. That way the wires aren't tight.
