    Roger that sonny,

    LWB....even has a correct /5 and or early /6 extended LWB swingarm, with the welds. My 73 has the small battery box.

    NICE!

    I have one, as my daily and ONLY rider.

    COOL! :evil

    The goal is to have this sucker ready for barber...thats a lofty goal. When all the parts come in, the Atlanta crew can expect a call for a tech day :)

    Things to do on said day:
    -Pull the rear wheel
    -Pull the swing arm
    -Pull the transmission
    -Lube all splines
    -Pull the top tripple
    -Grease steering head bearings
    -Drain forks and refill
    -Install new wiring loom
    -Mount new tires (if I have them)
    -Set points gap and time
    -Set valve lash
    -Rebuild carbs (I love doing this one so I'll do it in one night)
    -Install carbs

    That's all I can see doing in a day with 3-4 people and beer. That won't get her cranked, unfortunately. I need to completely strip and re-line the tank...so maybe I'll order the POR15 kit and get on that ASAP.
    Mean while, the r90 is running cool on one cylinder and carbon fouling 100% of the time on that cylinder. I'm blaming the boyer ignition...piece of crap.

    *PS: can we do this NASCAR style with jumpsuits and air tools?

    Took the fairing off and temporarily put my Magura europa bars on. That's about all I can do until the slew of parts come in.

    That extra 2 inches makes the difference (that's what she said?)

    I stole the tail light screws for the r90 :(

    Bonus. I really love carbs and I really love tearing them apart and rebuilding them. It's some kind of weird OCD now.

    I like that method you have of randomly placing the parts on a towel all in one big jumble. Guarantees the more even wear of parts by having them rotated from side to side every year. :lol3

    Oh, there's a pattern you say? :poser

    Just joshing ya.

    What a lucky guy. Already has an amazing 90 /6 and now gets to make a beautiful /5. Someday I'd love to have a /2 to park next to my /6 but that'll have to wait. It's dumb how all the best things cost money. (I don't know if I believe that the best things in life are free....)

    Looking forward to seeing some progress soon!

    Tires are here. Want to keep everything stock, original and period correct on this bike so I went with Dunlop K70 tires. Seriously the best looking, modern compound, vintage looking tires I've seen. I hear they aren't shabby on the gravel roads too :evil

    Although I really like those Dunlops on a lot of vintage bikes, they never came with them from BMW. So while they aren't stock and original, they are at least period correct.

    BikeBandit. They're perpetually "on sale" there too. I steer away from BikeBandit for everything but tires and tubes. They tend to have the cheap rubber prices and ungodly fast shipping.

    I haven't been sitting idle, just had a set back. The right side top end has a lot of old gas/rust in it, so I pulled it and I'm trying to get the blasted header un-seized from it so I can clean it out. New tires are on, old wiring harness is off. New wiring harness is in place but not hooked up. Frame and engine have been scrubbed and new euro bars are on.

    The tank is in a vinegar soak currently, before I start using the POR15 kit. Also, 15 year old gas smells HORRIBLE.

    My brother has a spare gasket kit for the top end, in addition to push rod seals. I helped him install an endura last on his toaster in exchange for those on the cheap. Doing everything I can to stay under that $2,000 mark!
    Funny story time. I keep 3 bikes in a row in the basement (others are stored off to the side,) the bultaco, r90 and r75. As I was pulling the top end off the r75, a water main busted right above all 3 bikes. Living in Atlanta, for some stupid reason, I can't shut off my water main at the street with out some proprietary tool. Being sunday, the water dept is not open. Their emergency line really doesn't get someone out there fast. As gallons of water is pouring out, I call 911 and get the firemen down there to turn it off. The bikes were under the water for about 10-15 mins before I could pull them out. Firemen got there and shut it off later. I cleaned all the mess up, fixed the pipe and the atlanta water came out and turned it back on the next day. The dude accidentally left his tool to do so, so I win.
    Looks like no water got in the cylinder/engine of the r75 :)

    2 day vinegar soak, rinsing with baking soda (to neutralize the acid.) This is before I even use the POR15 kit...vinegar is amazing stuff.
