    I've got a 99 605 for sale if anyone is interested. I bought it for a project and just don't have the time. Got a box of spares, including some plastic and a tank. Runs good, just needs a battery. PM if you're interested. I'll make you a great deal!

    Dammit! Where were you two weeks ago when I was shopping for a 605 (for the past two months)? I found an XR400R last week and bought it instead. [​IMG]

    Dah well... good luck on the sale to some lucky fucker. :freaky

    Hey all, life happens and the 87 ATK resto project took a back seat.. Finally getting around to working her again.. The entire year(s) long resto project here.. She's now to the point I can strip suspension and have all reworked.. :rofl

    Decided to show Ms. ATK some love. Several things I wasn't happy with -

    1. The rear fender hanging below the frame rail
    2. Wiring routing going to tail light
    3. Leaky o-rings at engine outlet to oil cooler.
    On the stand, ready for fixin'..

    I spent 3 hours fabbing a mount from the right peg to the engine stand. and it bent on the first application of force. Oh well..[​IMG]


    I like the FJR headlight reflection in the background. Hey! Let ME in the nice warm shop![​IMG]


    Here is where the O-rings were leaking. New o-rings, and straightening the holder bracket fixed it. Of course, I first had to remove all motor mounts but one, then jack the engine up so those stupid bolts could be removed. What a PITA.[​IMG]


    High tech at work...

    On to the carbs and leaky float valve. I have both these carbs. The No Fit carb had better main jet baffling, and the needle valve and seat looked identical. So I swapped parts. Made one good one out of both of them. And, apparently, it worked!

    More pix later of modifying the rear fender for a better fit..

    I had an ATK/XR kit bike for a short time until I found out it was stolen :cry I returned it to the rightful owner and it all worked out ok in the long run but I sure do miss it!

    Good on you for doing the right thing. I once found pieces and parts of my TT500 in a swap meet. The resultant 'meeting' was not nice.. :eek1

    Well the rightful owner was nice enough to give me what I paid for the bikes (he really didn't have to) and I was nice enough to give the bikes back (I really didn't have to) :D Authorities could care less about it as it was a civil matter and I lost a fair chunk of money and time but I couldn't help putting myself in his shoes so I feel mostly good about the outcome other than I lost two of the coolest bikes I've ever owned LOL.

    I called a couple shippers when I was still shopping around, and their quotes scared me off from that idea. 50 to 75 cents a mile IF the bike was even on their regular route.

    I'm kicking myself that I missed Pantera's '99 605 DSES. Dude lives three hours from me, and it went for $2200. :baldy

    I started lusting for one in October, and he had sold his in August. Dammit dammit dammit.

    I have Panteras bike actually. My buddy in Asheville bought it and then decided to vintage road race BMW's. I bought the ATK to build a hack bike but decided I would rather ride than wrench.

    And now it's in Vermont, and I'm broke. Damn the luck. [​IMG]

    It worked out okay, really. I'm tinkering on a pretty decent XR400R now. The cam chain swap is a bit more complex than that of a Rotax 4T, but it'll be done soon. [​IMG]

    My jetting sucks!
    It won't start with choke on..
    The drill is turn gas on, decomp kick through with choke on about 6 or so times
    Turn choke off
    Kick
    Kick
    Kick
    Kick
    Kick
    Kick
    Kick
    Kick
    Cough!
    Kick
    Kick
    Kick
    Start!

    When I get it dialed in I'll post up!

    In the mean time..
    Project ATK is getting closer and closer to being an bike actually worthy of abusing in the dirt as all good dirt bikes should be. Today got her 'lifted' off the suspension to remove forks and rear shock. I gotta say Thanks to my bud Gupster for building the bike rack and lift.. I'm getting to old to be crawling on the floor like the 'good old days'..

    Front forks and rear shock ready for Independent Race Shop, San Luis Obispo, CA.[​IMG]
    1989? CR 250 cartridge forks. Supposedly the 'ones' to have. After IRS gets done with them, I'll have a better idea of what they 'really' are.. [​IMG]
    Yeah, it's a bit scary to put a 5k dirt bike up in the air with a 17k HD sitting underneath. That's why I have the big turnbuckles and custom jack under the ATK.[​IMG]
    And TieDowns too! [​IMG]
    The exhaust is another issue I don't know what to do with.. The rear tire hits, it needs be spaced about 3/8" away. I'm considering just building a new system from scratch and be done with this headache.
    [​IMG]
    Naked, the forks are rear shock are both leaky. I hope severe corrosion hasn't eaten at the internals. [​IMG]
    Back in the day, I had RaceTech do the work. Hopefully, IRS can do a good job locally for less money..[​IMG]
    When done, this bike must be able to handle severe abuse, run reliably, and handle great. I have another motor for her, it was the race engine, which I'll detune, rebuild, and stab into later. Just because she is old school does NOT mean it can't work. [​IMG]

    dcarver, if your bike is had to start try going up on your pilot jet. I'm no expert bt I have succesfully jetted a few bikes from scratch.

    dcarver...the one thing about tm flatslides on our 4stroke engine is to not USE the choke at all!

    My jetting right now(im fine tuning after adding an hrc replica cam) is 20 pilot, 220 main needle in 4th. needle is the leanest 6fj41 If im not mistaken

    keep us posted, bike is looking great

    All ktm EXC,620/625/640 rear wheels will fit into the ATK with a slight spacer mod on one side. Suzuki DRZ400 wheel will fit as well as that is a straight fit into a KTM. Call Titman racing in QLD as they are the distributor for Talon hubs and will tell you what else should fit. The 94 ATK had a specific sprocket bolt pattern that wont cross refference so going to a KTM or Suzuki hub will give you a better range of rear sprockets. you'll just have to spring for a new disc.

    Thinking about parting out the ATK, can't seem to get any interest in the bike whole. Any thoughts?
