    Do yourself a favor right now and order the next size up pilot jets too.

    Great post going on here. Good learning for the next time I screw up and buy a 1st gen V-4!

    wow. those carbs appear unusually filthy !

    somebody didn't bother to read the FSM, as carb removal instructions do not suggest removing the plenum while carbs are in place on the bike, why the tube broke.

    if you know how to do the blow test to check the health of the slide diaphragms, i'd suggest, if they are good and move up and down nicely, not to remove the top cap as no dirt gets in there, and you might have hours of grief trying to get the shrunken rubber back in the grooves properly. hours of grief. if you need to resort to "stickum," the diaphragms will likely be damaged upon any later removal.

    Lol!

    Capt - did drill the pilot plugs and pull/clean/etc - it wasn’t bad at all, good call.

    Found a lot of blocked emulsion tubes, all bunked with varnish behind the jet itself. Most of the floats were 1mm off in one direction or another.

    Now just trying to figure out where these two springs should be. Seemed like they fell off when I was fiddling with the carb in front right - the one with the throttle plate:

    small one goes between throttle interconnections for synch , larger one goes between carbs.

    Ok - yes, found the missing throttle interconnect - getting all those back together is going to be a pain.

    It’s unclear from the manual picture where the two larger ones go (found the second off to the side).

    And yes - the manual does not tell you to take the airbox off. For some reason I went into autopilot and am now paying the price.

    Re: vacuum piston rubbers, honesty they went back without an issue. I used a little dab of grease to hold them in place against the carb body like I did with my 350 carbs.

    Excellent… remember Ed the install goes with the plenum on. I should have reminded you earlier… sorry brother.

    My fault for reading more of the manual than is actually there

    Old fashioned way - tub of ZEP (general cleaner/degreaser) with a soft nylon brush after all the brass was removed, then deluged with water, blew it dry, carb cleaner in all the passages and brass, compressed air all that dry.

    Hardest thing used was probably the nylon brush or the nylon pipe cleaner - no hard wires and all the gunk is out. Ignore the K&L carb cleaner on the bench - I took it out then thought better of it

    Old place had an ultrasonic AND a parts washer that I would’ve loved right now, but whattya do.

    after any deep soak you need to lube the throttle shafts or risk them seizing up during a storage period.

    Yes - that was done. I’m not sure what others like but I use this stuff religiously:

    https://www.amazon.com/Tri-Flow-Squ...ocphy=1022762&hvtargid=pla-315876899021&psc=1

    They make it in a spray bottle too, but it gets everywhere.

    It’s got liquid Teflon in it. I used it on the throttle shafts and choke shafts, as well as a *light* coat around the vacuum pistons to get them moving. It’s my go-to cable lube also.

    Doesn’t hurt that it smells like bananas in like a chemically-but-pleasant-banana kind of way.

    I think the Squirrel'd one wants to know that you strung your carburetor jets up like a guitar. err... that you ran a guitar string or something similar through the orifices to verify that they are clear. I use fishing line since I've never actually remembered to snag some guitar string from anyone.

    Ah.

    I did not - put them up to light, saw light. Sprayed cleaner in one end, it came out the other.

    All the rest of the gunk in there disintegrated with some carb cleaner.

    merely seeing a peek of light is not the same as verifying that the hole is FULLY open with a .010"-.012" guitar string .

    i' ve seen many jets that showed some light but were not FULLY clear until they were poked with a wire, physical cleaning not just chemical carb spray.

    Take an old cable, any old cable. Cut one end off and pull out the twisted cable from the sheath. Now cut about 12 inches off. Remove one strand from the cable. You just created the perfect jet cleaner. It has curls in it, so when you run the jet up and down on it, you know the wire is touching the sides of the jet and cleaning it. Finish with carb clean and compressed air. Win.

    Ehhhhh I’ve always steered clear of metal stuff in the jets. They’re miles better than they were - I feel good about them.

    Just waiting on the SS tubes and those tiny little cotter pins that hold the linkages and we’re back in business.
