    Started to redo the wiring today. First picture is the backside of the main fuse. Second and third picture is the connection for reg/rec. The red wire goes directly to the main fuse since the original fuse-board is gone.

      Had to trim the box a bit in the front and bend in the sides some in the middle, to get the fueltank low enough, but now it fits better than expected

        All very nice work, lovely!
        Too late now, but it would have been nice to punch in the tank sides a bit for knee bracing. Something sorely lacking in gas tanks of the period.
        Anybody who's done some very hard braking on a track or street knows why that's a small thing for a big help.
        PS: You can still buy or fabricate a fork brace, very important on those spindly fork tubes.

          The tank can be propped up for easier access to the m-unit:

            Thank you! Yes, knee indents would be cool too. I had a Kawasaki zx7-r Ninja before and the knees fit perfect when braking, and as you say, it's a big help
            I don't know how much it would help on this bike though, as the rearsets are positioned pretty far towards the rear. This makes the leg angle so that when I sit towards the front of the seat, the knees are where the rear camshaft-cover is. A little higher when i sit towards the rear. As you can see on the pictures below, the cx 500 tank is pretty narrow, and has a shape that allows the knees/thighs to fit pretty well if I have may toeballs on the pegs. Not nearly as effective as well made indents though.

            I was looking into fork braces, espesially the Tarossi. But as I miss the braking power of the Ninja, I've decided to do a fork swap later on. I've bought a set of GSX-R 2005 USD forks with radially mounted calipers.
            The calipers I'm going to sell again as they give the wrong ratio for the radial master pump I bought. The master pump is 16mm as that was perfect for the original calipers. The Yamaha R1 monoblock calipers are highly rated and the piston area makes for a perfect fit for a 16mm master. Lots of amateur racers do this swap on their GSX-Rs. Also I dont want to buy new Accossato levers as they were pretty expensive.

            I'll hopefully be able to do the fork swap next winter. I'm waiting for better exhange rates for the dollar before I order a front wheel from Cognito Moto

              Pretty happy with the decision to powdercoat the rearsets gloss black
              I haven't finished the left footpeg yet, but the season is getting close to the end and I want to get the bike on the road, so I'll go with the black nylon prototype for now

                Those look good. I was thinking another benefit would be; they won't chew up your boot soles like bare aluminum race pegs do.
                Really shortens the life of expensive, over engineered racing boots.

                  My father got a new lift/table for the garage and it made working with the bike so much easier

                      Heatshrink soldering is an extreme timesaver (at least for me who hasn't used a soldering iron in ages).

                        The handlebar controls I bought came with one momentary and two laching buttons. I knew this in advance, but I bought them anyway because the housing are good quality and I have some spare M12 momentary steel buttons. What I didn't know was that they were non standard threads and I don't have a tap that fits. Thankfully they came with some low profile nuts and the housing have just enough room for them to fit.

                          There's no room for the ignition-lock on the top triple so I'll have to place it somewhere else.
                          Anyone have a suggestion? Pictures are welcome

                            I'm thinking maybe over the carburettors, on the right side where I've marked with a blue dot.

                              Accossato PRS2 radial master with matching clutch lever. Blue ATE brake fluid matched the blue stripes on the tank and seat nicely

                                Very temporary varning light panel Will use this until the new top triple is finished.
