    Cingu.. err AT&T. I'll check into it to make sure though.


    EDIT: Oh wow, MMS messages have gone down to $0.25 each. But I see nothing about emailing myself yet.

    Tested out the rectifier to see if it was worth salvaging and it failed. I didn't think it would work because the plastic holder was slightly melted on the rectifiers side. I hope the TCI unit didn't get hurt though. Any way to test that without another running bike?

    These were taken this morning. I've done nearly zero work on it today, so everything is what was done last night before it got too dark to see.

    As you can see my supervisor has claim this spot to place his observation post. You can see the motor covered up in the background.

    And the work I did do today. I messed with the carbs a bit trying to clean them up and evaluate their repairability. Here's the engine side of them.

    The best way ... the easiest way ... the bottom-line way to test the Ignitor is to pull it and test it in another bike.

    Nothing is easier!

    How much you want for the little red chair?

    You need to pull the hats off the carbs and have a look at the diaphragms. If those got damaged your parts bill just went up a bunch.

    Already did. Nos. 1 3 and 4 look okay. They soft and flexible with holes ir cracking. However, No. 2 (the one the was leaking and where the fire started) feel kind brittle. It's flexible still and there are not any hole, but the rubber doesn't feel right and tiny particles of it come off on my fingers when I rub it.

    I wouldn't trust any of them. I would replace EVERY rubber part on those carbs. They are just too touchy and you will spend a buttload of time chasing demons in the future if you don't fully rebuild them.

    Good point. Keep the advice coming (yes I know, it's a foolish affair so that not flavor of advice :D)

    Quick question. I was planning on sandblasting the frame and then repainting it. My dad said that wasn't a good idea because the metal in the frame is so thin that the sand would tear it up pretty badly. Should I drop that idea and just hand sand everything?

    I don't think a light sandblasting will hurt anything. Just go easy and don't stay in one spot. Keep it moving....change direction away from the frame, don't stop and start while on the frame. If you are really worried about blasting the frame or the welds away, use walnut shells or some other softer abrasive in the blaster.

    Don't "Sandblast" ... "Bead-Blast" and "Media-blast"

    Use a bag of Beads to blast the Frame. They don't score the surface and remove the paint down to bare metal without harming anything.

    You can Blast the Engine clean with a softer Media ... like Walnut Shell.
    It will strip-off the fire damage and refinish the Aluminum quite nicely.

    Glass beads will strip-off flaked and pitted Chrome and leave the surface close to prepped for painting or Powder Coating.

    Ugh, effing rain and final exam means no work today. And it's supposed to get into the 20's-30's throughout the rest of the week so may not be much progress then either. :(

    Well, now I need a carburertor. Was dicking around with the no. three carb and broke the damn throttle arm off. :| Maybe I'll start planning an EFI conversion and do away with the carbs all together. Lousy pieces of...

    After cleaning up some more of the carb units, I'm gonna need a whole new set. The housings are incredibly brittle and pitted, the slides are swollen and won't slide right even after sanding them a bit. I don't think the fire caused this as the one in the best condition was the No. 2 where they fire started.

    I'm really considering adaptin an R1 or R6 EFI system to this bike. Anyone know of someone who's done this? The R1 throttle body spacing looks very similar to the carb spacing on the XJ I have. Might take some fiddling to get it to fit though. I'll keep you guys updated on how it goes.

    I actually found a guy who took a GSXR throttle body and a MegaSquirt system on his XJ, but he spent $900 to do it. 8O

    Will 82 XJ750 carbs work on this 81 650?

    I just spotted your project.

    You're going to be real familiar with Arkansas Wings Cycle salvage before this is over.
    I don't know if those 750 carbs will fit or not, but I can bring mine over to find out. I've got to pull them off of the four-wheeler soon anyway.
    I seriously doubt that the jets will be correct if the bodies do fit.
    Likewise, we can check your ignitor on my Bayou and see if it still works.

    I don't have a lot left of my XJ for parts, but I do have a bit of knowledge if you want my help. I've got wiring diagrams stored away if you want to build a new wiring loom from scratch, or just get a salvage one from Jayson @ Arkansas wings.

    If you're serious about that salvage engine going down the road, yell at me.
    I'm just down the street.

    I think the 750 carbs will fit, however you will need to swap all the jets and possibly the cable hook-ups will be different. You'd be better off getting a set of 650 carbs from eBay or a salvage place like eatatjoz mentioned.

    Oh wow, you are close to me. Do you own a shop? I would really like to test this ignitor out.

    Anyway, I've already ordered another harness for $10 shipped. But I did talked to Jayson and he doesn't really have a lot of stuff that I need.

    Oh and I went ahead and ordered the 750 carbs. I have all the jets from the set I busted (still in their places). I'll just have to swap them out one at a time.

    Not a shop owner, just a tinkerer.
    If you give me 'till after the weekend I should have my carbs cleaned and ready to try that ignitor out. I'm putting my Vmax carbs back together as we speak, and I start on the four-wheeler tomorrow.
    As far as shops in the immediate area, I recommend Conway Cycle or Al and Ben at the Cycle Shop on McArthur in NLR.

    Don't touch those jets until you soak them in a penetrating oil for a couple of days. If they're seized, you could make them worthless with a slight slip of the screwdriver.

    Oh, and Jayson does have a bunch of stuff that you'll need. He just doesn't know it.
    I got the last set of good pick-up coils from him last year, but he still has a bunch of cross over stuff.
    You just have to walk the yard.
