    I used a Brutale seat......I like that "pocket" right behind the tank.

      Wow, that is one unique motorcycle! It looks like a lot of work, design and money was poured into it!!

        Quick update.

        I secured a 636 motor from JD Hord. It is being built up with +1 pistons (11:1) and the X8 race cams. Can't wait for that to be finished! Also, it will be using an IgniTech CDI and tuned on his dyno.

        From JD's bench:


        Today, I got the Penske 8983 that was recently posted by Garbodp. Then, quickly mounted up! Thanks Brian!

        I also attached an OEM connector to the brake pressure switch.




        The swingarm didn't have the OEM decal, so I ordered one up from the local dealer. I slightly offset it to the right to clear the gouge. It's a bit on the bend to the right side.




        The rest of the time prior was spent tearing apart two harnesses to re-use the OEM connectors and some of the wiring. The other harness was from my 900rr. The gauge of the wires were a size or two smaller. That must be part of the factory weight loss program! I cut and removed all the jacketing and old terminals. I ordered new terminals from Vintage Connections. The switches (left 600rr and right 900rr) were re-worked to commonize the power feeds. I took them apart and soldered on longer wires. The old wires were cut short. I use barrels to do the node crimps, braided the wires and shrink wrapped them. The shrink wrap here was some generic stuff but I'll probably order some Raychem DR-25 for the rest of the main harness.

          Now, I originally thought the hub centered this way would also center the wheel. When I put the wheel, their is barely a mm of clearance to the swingarm. That's with a 180 tire. I later read the wheel has +3mm offset difference with the stock wheel. This means the hub or wheel should be 3mm to the right. So, to fix it, I'll put the 5mm spacer on the right side instead of the left. It's not exact but I figure 2mm more to the right is better than 3mm to the left. I'll probably shave down the spacer a couple mm to center it all. Or maybe 2mm is not that bad??
          With the 748 hub centered in the swingarm, it should effectively cancel out the difference in wheel offset. It's normal for a 180 tire to be a close fit, especially with some of the wider 180's, and some members grind the swingarm for extra clearance.

            Are you sure about that? It would seem that's only true if both wheels (Hawk and Ducati) have the same offset. I measured my offset and it's more than the Hawk wheel. Plus, the 848 type wheel I'm using was meant to be used on the 848 hub. That hub sticks out 3mm more than this 748 hub. That leaves me to believe I have to space my shorter hub out to the right by 3mm. I removed the spacer so I can move the hub freely. Either way, I'll probably check the alignment of the wheels to make sure.

              Hmmmm, now you have me wondering again. I'll have to wait until after Wed to check on my bike. I was basing this all on 748-998 OEM wheels, but according to the Ducati forums, the 848 and 748-998 wheels are interchangeable, so they should all share the same 22mm offset. The 848 hub being 3mm wider than the 748 hub doesn't necessarily mean the wheel is offset by that 3mm - the 848 spindle's wheel mounting surface could be 3mm closer to the hub, or the 848 swingarm may position the hub 3mm over compared to the 748 swingarm.

                  Yes, you bring up a good point. The mounting point on the 848 hub does indeed protrude out 3mm more. I know as I had both at the same time. So, in your observation, the swingarm could be different. So, a lot of factors in play that affect the offset. The best indicator is to just measure it.

                  Cool! The tail piece finally arrives. That means the engineering development for the subframe will now accelerate! But, no rush on my part. I have a lot of work to do [& more $$ to save for this ensuing money pit of a project!]


                  As far as the progress this past week: I finished the fuse box design and ordered parts. It will take about 3 weeks but I can keep going on the harness design. I have most of the parts but I'll have to assume locations for the motor connectors and parts on the subframe.

                    All my experience is with the 748 hub and wheels.The 3mm shim on the Hawk spindle after modding takes care of offset.

                      Good to know. Thanks. It's correct then.

                        Update time...


                        I'm still working on getting the electrical together. I've received the parts from Mouser but the pcb is still being fabbed. But I can still work on the connectors.

                        Here is a shot of the 2 fuse block connectors (the gray and black Molex), the IgnitTech connector, and the OEM solenoid connector. I can't finalize these parts until I anchor down the components. They'll likely go on the subframe and that is about a week or so away.



                        Also, I decided to change out the handlebars with clip-ons. Big change, I hope it works out ergo-wise. I got a pair of 1198 OEM clamps and I already had a set of spare Woodcraft bars. Easy install, except I had to mill a half round hole in the end to allow one of the 6mm pinch bolts to fit thru.



                        This view shows where the end of the left side switch, right side switch and the ignition switch connector end up.



                        You see the ignition switch haphazardly hanging off the top clamp. I designed an ignition switch bracket and WW Bill put his finishing touches on it before machining (milling?) it for me. I'll show that once it arrives.

                        View of front routing of cables, harness, etc.


                        The black and white connectors are for the gauges. Luckily, I had a set of matching connectors off the 900rr harness I took apart.
                        Kicking around ideas for the steering stop. I like the BTT design. [you listening, Bill?] but I want to mount it on the existing threaded hole in the front. I'll need a matching one on the left side. Should be enough meat there. I want to have adjustable stops (a la Duc Monster) like so...





                        Another purchase I made was the instrument panel. I wasn't happy with the current products out there. Mostly I didn't like the graphics and the price. I hinted before on a 600F4i and here it is:



                        Everything should work fine except the fuel gauge obviously. The FI red warning light will be wired to the fan switch as I like to know when the fan turns on during hot days. Also, the tach face will need to be adjusted. I'll either cover up the 10-17k numbers right on the dial or on the glass. It depends how easy it is to take apart. The IgniTech output should match the tach input at 1 pulse per crank rotation (360). On the 4 cylinder bikes, there are 2 sets of dual coils. Each fires once per 360, spaced however degrees apart. The Hawk has the same setup but there are 2 plugs per cylinder. Same coils and same timing.

                        The other needed change is the water temperature sensor. The Hawk has an analog sensor and I need a digital sensor. The 98-99 cbr900rr sensor will work. I hope the thread pitch is the same! The last needed change is the speed sensor. It's normally taken off the front sprocket or the tranny. I'll need to design something to attach the front sprocket to the speed sensor.

                        Also, you see the 996 steering damper. I hope to engineer that on this bike as well. It should work if mounted the same way as the 996.

                        A few last notes.
                        * I have a plan to pick up the JD motor mid March.
                        * I have a set of crap carbs coming tomorrow that will need rebuilding.
                        * The tank will be sanded down in the coming weeks to be prepped for paint. Still kicking around ideas on color.
                        * Searching for an OEM seat to match the narrow small NSF100 tail. My current cbr300r is small enough and it's easy to check fit for that obviously. The other seat I like is the RSV4. Not sure of it's size but it looks cool. For it to fit, it needs to be around 12" wide. That's a small seat.
                        * Searching ideas on the front headlight. KTM Supermoto style, HD V-Rod, 796/696 Monster. Something along these design lines. Sharp, mounted low, bright, modern, angled.

                                really great stuff here! Hope the clip-ons give you enough steering lock to be usable. That steering stem looks a bit rusty! Like the adjustable stops though!
