    Luke and his helpers have been grinding it out the last couple of weeks, here are a few recent pics that help tell the story.

    Mr Fisherman came out and lent a helping hand;

    Loud Al is a big part of the operation;

    Another shot of Luke and Mr Fisherman, late at night Luke's eyes do begin to glow a faint red;

    Almost ready, just a few more bits to be fabricated and a little more carb tuning;
    [​IMG]

    The carb tuning tapped into Luke's vast well of patience, but he persevered and got it right. Here he pulls the carbs for the umpteenth time, no small task;

    Yesterday, loading up;

    Nice box;

    About 4:30, I'm leaving for a grandson's basketball game, said my good byes thinking they would be done and gone when I got back;

    I got home about 7:00, and Luke was still working. Turns out he had several more items to build or fix and so I asked what could I do? He quickly sketched out a GPS mount and said "go to it!" At 10:30 I finished the mount, he finished the fuel can tranfer caps he was machining from aluminum, and was in the final stages of loading when I went in to bed. Heard him pull out about an hour later, I'm sure he was dog tired! :eek1

    Luke has done a masterful job of taking one of the most unlikely bikes on the planet and making a pretty competent off road beast out of it, I was skeptical at first but have now been won over. Sure hope he and all the OSR crew have a safe and successful trip. :clap

    Stay tuned for updates. :D

    Wow, really coming along. Looks great.
    Is that little spot light on the bars the only headlight you have on it?

    I see tail, turn and horn and I seem to remember you getting it plated but no headlight?

    In Cali we have to have a headlight on at all times even on older bikes. If it has a plate it has to have the light on.

    Looking good! Wish I could be there to see it in person but I will be routing you on from the opposite corner of the continent!

    As you might have guessed, I've been pretty busy the past few weeks, hence no updates. So, a quick summary:

    I'm now in San Diego, staying at a friend Ted's place with Cory and Paul. Allan, Laura, and Dave will fly in tomorrow. Paul and Laura are driving a Subaru in the race so we are all a team of seven. We got here yesterday and have been doing last minute prep. Mounting up navigation stuff for the race, getting the fuel tanks mounted properly, putting on fresh tires. Things like that.

    Yesterday was a bit odd, as it was cool and overcast, but today was a true SoCal day. I applied sunscreen to my outside and In-n-Out to my insides. First time for each in a year. Did some welding on my bike and the Subaru, good times.


    A few pictures:
    I-5 south, this is the first part of CA you see from the north; very nice.

    Paul had some work to do on the Subaru too.

    I've got a little more work to do on the bike, but it's basically ready. Just have to make up a pigtail to power one of the GPSs, and run it up and down the road to see what kind of fuel consumption I'll get.


    I'm pretty excited for all this, thanks for all the good wishes!

    Bike is looking great and I am glad the weather has been good. It is supposed to be beautiful the next couple of days. It is gorgeous right now here, 30-40 north of you.

    This time of year we often get that morning gloom, overcast, heavy dew but it usually burns off by 10 or 11 o'clock.

    Keep us posted on how it runs and handles. Sure looks good.

    Well, it's bad news for the CB. It ran great on an 80 mile test ride through the SoCal back roads (great roads, btw) and got 32 mpg, which isn't great, but with the extra fuel packs it's good enough for Mexico.

    Firing the bike up before tech inspection on Saturday, it made a pretty aweful noise, kind of like a ducati clutch. So we pulled the clutch cover in the parking lot of the hotel and discovered that the actuator lever was dragging on the clutch basket sometimes depending on the pull on the clutch, so we fixed it and pulled it back together.

    Sunday, it ran perfectly on the first special stage. It was a few miles of soft sandy trails followed by a long run on dry lakebed. The bike handled better than a 400# bike ought to in sand, and really really well on the lake bed.

    Two miles into the first transit the motor locked up on the highway, and that was the end of the riding. We tried to fix it on the side of the road, but couldn't get anywhere, so trailered it to the first day's finish at Bay of LA and worked on it all night. We freed the motor up enough that we could disassemble the top end, and it all looked ok By about 1:30 am we had pulled the top end, unstuck the rings (so we though), put it back together and fired it up.

    The next morning we got up for the start and after getting ready to go, took the bike for a quick test ride before starting the special. It made it about 100 feet and locked up solid again. Allan and I spent the morning tearing the motor down again, and it turned out that the third con rod had come apart and the crank bearings had seized. There was no way for us to fix that, so that was the end of the race.

    We stashed the bike in a storage yard in Loreto and drove with the race to support Oregoncoast in his Subaru.

    I was pretty gutted by the whole thing for the last couple of days, but when the bike gets back in a couple of weeks I'll tear into the motor and see what happened.

    No pictures yet, I have some video of the first stage that I'll put up when I get to a decent internet connection, and Allan will have some pictures when he finishes driving home; it's now vacation time, so that will be at a much slower pace than the drive down.

    When we heard the news Jani was almost in tears and we were both pretty upset. Bummer! No matter what, you did build an amazing machine and it proved itself at the D100 and apparently at Laguna Salada. Engines do fail, it just happens.

    Anyway, the main thing is you are all safe, nothing else really matters all that much. See you soon and enjoy your vacation, there is always another race! :D

    Bummer dude. Come home safe and we'll fix it.
    I bet that first special was worth the price of admission.
    Enjoy the vacation, you have more than earned it.
