Got the tail mounted up and adjusted for fitment. Now on to the custom hinged solo cowl, undertail, trunk box, and battery tray.

Chopping up the Chinese rear F4i seat to mold some parts onto the Orange 1000rr solo cowl, to use the existing locking setup from the F4i subframe. I will be building a custom undertail to house the key barrel to unlock it, and it will hinge forward like the 954rr trunks do.

After some trial and error and trimming a few times I was happy with the fitment. Added on some tape to hold it in place and "tacked" it there with some epoxy. Once that dries I will retest the fitment and if I'm happy still, onto the hinge build, which will be bolted to the same brackets that hold the tail currently.

Since I will be building a nice water tight trunk box inside the undertail and the new tail doesnt allow for a good way to keep the whole battery tray, it will be getting trimmed in half and mounted differently.

Keeping all the important stuff up front, which is hidden by the new tail anyways.

A cleaner cut and more will be trimmed later once I start the trunk build and figure out rear brackets to hold the tray. Also, I started building some "prettier" brackets instead of the roughly bent ones from Aluminum. Not too worried about them as they are all hidden but in the end a nicer setup will be used.

 

cool project! Thanks for sharing your progress

 

Picked up some sheet metal to make the undertail. The plan is to fab it out of foam board or cardboard first, then use that as a template for the metal to trim.

Also, dont mind the mess, but I got the trunk locking mechanism molded to the underside of the cowl. The excess glue will be trimmed and sanded smooth, sealed up and then painted with the rest of the cowl to match the bike.

The lock is super snug, fits on the frame just as the F4i seat did. This gave me a good hold for me to start fabbing up the front hinge, which will be really close to how the 954rr trunks hinge open.

Once I am done with that I will finish up the new brackets, which will be powdercoated and CNC cut. I will also start on the "trunk box" this weekend that will be mounted and sealed up inside all of this. Watertight and way larger than the OEM "trunk".

 

Alright... Made some more slight progress on the bike today.

Worked on the hinge setup. A standard hinge wont work due to the depth of the cowl, it will hit on the plastic. And since I could not find a hinge that went up AND out, I compromised. A dual hinge setup that I mocked up worked very well, so waiting on the epoxy to dry on the first prototype and if it works then I will also get that custom made on the CNC to match the rest of my brackets.

Easiest way to describe it was a quick sketch on the paint app...

The second hinge is limited to only rotate about 45*, enough to have it latch securely, and clear the plastics when lifted.

Also pulled all the plastics and started chasing some electrical gremlins I've been having. The right turn signal would not work, even though I was getting an indicator on the gauges. Could not find where the loss of power was happening so I ran a new wire to control the signal from the front. Voila.

1000rr taillight looks and works awesome now.

Then I started mocking up for the undertail. Measure, measure, measure, then cut some cardboard for the mock. I cut and folded the edges up so I will have a mounting surface on the inside of the subframe. Once that is fit I will just trial and error to get the lines to work around the tip and the taillight.

The rough first prototype for the undertail.

And just an idea of how big the "trunk" will be. I will be making a box that is sealed up to put down in here to keep everything nice and dry and where it needs to be.

I've also got some plans to clean up the ends of the subframe that were chopped since they will show with this undertail design.

 

Ta daaaa! Is this the equivalent of Lambo doors on a motorcycle?

Small update, few pics.

Got the cowl sanded, disassembled and painted tonight.

Also got the undertail finished up, trimmed, and painted as well. I am using the press at work to shape the "trunk box" that will be mounted inside the tail after its sealed up and fit. Definitely thinking of building the undertail from fiberglass in the near future, but for now, the sheet metal works.

Ever been so happy to be done with a project? Not there yet, going to build a fiberglass undertail, but the quick sheet metal one will work for now.

Nice work Skee! I know this thread is a few years old, but I signed up for this forum just now (first post!) so I could ask if your 600rr swingarm swap gave you any trouble. Did the mounts on the back of the motor hold up okay to the 600rr linkage? Did you reinforce that mounting point in any way? If you're still around, I'd love to know!

 

Not sure if you're still interested in info about the swingarm swap.. but you should check out the F4i swingarm from the company "StunterX" it looks killer and you could keep all your F4i parts keeping the swap a million times less complicated. They even custom powder coat it. Last winter I swapped my front end so this winter I'm going to custom the back half of my bike


Those 2 pics are of my bike and the other is the pic of the swingarm I'm gonna eventually put
