    Thanks Dudlington.

    In further news...

    Undertail breather box installed



    Relays secured to the undertail with stock rubber fittings



    Ducati rubber straps keep the rest of the wiring in place



    Carbon fiber clamp for the shock reservoir



    No bullet connectors or "electrical tape specials" for this one--Amp Superseal connectors for the tail lights and signals makes it quick and easy to unplug everything at the track



    CF headstock cover in place



    GPS Navigation and speedometer--no fouling of the fairing and an unobstructed view of the gauges--job done!



    Well, almost. Still plenty of cleanup to do. A view of the bike and living room disaster area from above

    I thought the headlight needed a little extra detail (and it was a bit bright), so I made a lexan cover. I had black perforated adhesive vinyl, but that's just temporary--the white stuff arrived but the bike is on it's way to the MotoGP at COTA. I'll stick it on Thursday. I just used two M5 Allen screws and wellnuts to secure it.





    I got the GPS wired on Saturday, so now I have a speedo too. Took it on its second shakedown run--over 200 miles. Seems healthy.

    As mentioned, the local Ducati club is making the trip to Texas for MotoGP, so we all loaded up the rig to bring the bikes down.

    Photos from COTA MotoGP in Austin.

    White perforated vinyl for the lexan cover arrived before I left.


    Actually pretty bright (that's with the cover on).


    A couple shots from the corral.






    The Ducati Island hospitality area had a new elevated area overlooking turn 19 while enjoying your espresso.


    They also served us a very nice spread on Saturday.


    BBQ at The Salt Lick with other DRILL members who made the trip from Chicago. A mutual friend was dining with Kenny Roberts Jr and introduced me.

    The license plate bracket has great adjustability, but is a bit bulky for my taste, so I started making a carbon fiber one last night. I have some very sturdy (1-2mm thick, I think) carbon fiber sheet. Then...
    • On with the rubber gloves
    • Cut one wide CF plate for all the rear lights and license plate to mount to
    • Cut a smaller plate to bolt to the vertical tab on the subframe
    • Bevel the edge of the smaller plate to create the desired upward angle
    • Cut patches of twill carbon fiber cloth
    • Mix the 2:1 epoxy and hardener
    • Position the plates at the desired angle and spread a thin layer of epoxy over the area to be reinforced
    • On top of a sheet of aluminum foil, sandwich alternating layers of CF cloth and epoxy (I used 4 cloth layers for this)
    • Fold the aluminum foil over the layered CF patch
    • Since there's no vacuum bag, use a rolling pin over the foil to squeeze out the excess epoxy (pressing With a book may work OK too)
    • Peel the CF patch away from the foil and apply it to the back of the joined plates
    • Use a heat gun for several minutes to help it set up
    • Trim or sand away the excess


    At this point it was time to drill the holes but I realized my cordless drill wasn't charged, so I'll finish up tonight.

    Job done.

    I also installed an underslung caliper and went from a 15 to 14 tooth front sprocket. The ST4S gearbox seemed a bit tall in Austin.

    There were some part throttle issues with the fuel mapping, so the bike went back on the dyno on Tuesday. Much better. And when I arrived home, my license plate had finally arrived too.



    I also got some take-off slicks mounted on the black, 3 spoke Marvic "special occasion" wheels for when I really want to go period correct.



    I love the gold on the 916 bikes but I'm just not sure it's right for the 851/888, so I picked up another set of Marchesini 5 spokes, in black, although I prefer gloss to the satin finish of these. I'll have to figure out which way to go.



    So here's the underslung caliper setup. Still looking for a used billet rear caliper.





    Oh yeah--with about 600 miles on the rebuild now (plus a good amount of dyno time) I did the first oil change last night, going from the break-in oil to 15-50 full synthetic.

    I'm going to try to ride it as much as possible over the next few weeks--I'm doing Road America on June 30th and as long as I feel comfortable with everything I plan to use this for the trackday.

    At Road America and somebody parked their black and yellow bike behind me. Had the nerve to put a "1" on it too.

    Being up close to the Britten, clothed and unclothed, this weekend, a few things struck me. Just to clarify, it was the bike that was sometimes naked, not me.

    1. The airbox is shockingly tiny. It’s very cool seeing how air is routed to the airbox and underseat radiator, through the nose/tank/tail fairings.
    2. Carbon fiber everything. Yet for a bike that’s 70% CF, it’s ironic that the bikes racing numbers (#1) are fake carbon stickers…on painted but real carbon fairings.
    3. Cool details are everywhere, like the front end’s damping adjuster poking through the dash, or the front brake reservoir recessed into the top triple, or the clip-ons sandwich mounted to the triple.
    4. The bike is insanely beautiful, yet up close it was clearly developed for the singular purpose of winning races. The carbon fiber wheels (made years before BST or Dymag) and other parts have hundreds of pinholes, irregularities, and runs in the finish and were not built to please the mass-market consumer. All the more brilliant character.
    5. The owner (Bob Robbins) was exceptionally gracious and generous with his time and bike. Actually, bikes. He had several on site, including an 888 that Dale Quarterly rode. Mr. Quarterly trashed the Next Gen Superbike field and I believe finished 2nd in the other race...against a field of Panigales!
