    Fuel and air tubes showed up - they look like they’re great quality, but the one air tube is supposed to be a four piece, this one:

    I’m assuming the snorkel is to provide a constant reference for all four carbs, but I’m not too confident in that.

    I assume adding a three way barb connector between these two and re-creating the snorkel will have the same effect?

    Alternately, that tube survived my crude attempt at removing the carbs, so I could just re-use it.

    And naturally when putting the carbs back together I lost the throttle linkage bushing.

    This little guy.

    Anyone know where to source a replacement?

    Edit: I’m going to try making one out of bronze on the lathe, and all else fails there’s a carb body on eBay for $18 that has it

    Let me know if/when you figure it out. I was missing one on a carburetor I rebuilt, and I could not find a replacement anywhere. I ended up ordering a bunch of miscellaneous nylon bushings from McMaster-Carr and sanding one until I got one that sort of worked. It was not the best solution. It's like a $0.50 part, but essential that it operates correctly or the butterflies won't open correctly.

    HA! I did the same thing, the electrical insulating washers - they’re the right ID, but too large of an OD.

    I’ve got three plans in place:

    1) The nylon washers, I may try and chuck them in the lathe and see if I can tickle the OD down.

    2) Make my own out of bronze on the lathe

    3) I’ve spotted a few carb body and linkage listings that seem like they’re also selling the bushing on eBay. Usually about $15-$20 for the miscellaneous parts.

    Yep--that's exactly it. Wish I could have found one with the right OD, obviously. My sanding job wasn't the greatest. I had no other way to try to remove material though. I have a bag of 98 remaining, lol.

    I don't actually remember which ones I ordered, but this is the page I emailed to myself to order from: https://www.mcmaster.com/nylon-bushings/electrical-insulating-sleeve-washers-6/

    I'm curious what you come up with. I want to hear how it works out!

    I have a set of VF750F carbs with a broken plenum.

    I suspect the bushings are the same as a 500.

    One for each of you. Price is cost of shipping in a small bubble envelope.

    Might have to wait until this weekend for me to dig the carbs out.

    Ta-da.

    No slop, the linkage is tight.

    I’ll add any other hardware as needed but I’m well happy with it.

    4mm ream on the ID is a perfect fit.

    I did stumble on Billy’s website, but looks like I’m all set.

    Don't go digging too far on my behalf. The one I made up is on my buddy's bike, and unless I have a good reason, I'm not planning on pulling his carburetor off again for many years. But you never know. If you do come across an extra though, I'd pay for postage for sure. Just knowing it's not quite right on his bike kind of drives me a little nuts.

    Did Billy decide to fire it back up?! I reached out to him a while back when I was looking, and at that time he was getting out of the V4 carb rebuilding. He was going to check if he could find one for me, but didn't see one right away, and I didn't want to bug him anymore. I think it was very early pandemic. The website even went down. I now see that it's back up, and there's a 2022 copyright on the bottom of the website, so looks like he's back in business!

    and, alright... Ed's is way cooler. That's pretty sweet looking! Nice work.

    *edit - hopefully Billy starts selling the rebuild kits again. Website looks like it's in progress. I know you can source all of the parts yourself if you know what to look up, but... it was really nice to just buy the rebuild pack with all new orings and allen bolts and just know it was all going to be there.

    Made off of this highly detailed sketch:

    Easiest bet is just to bring the linkage to a machinist, or a friend with a lathe and have them measure and make.

    I Didnt know he quit for a while, I wondered why I only saw rebuild set ices and not parts listed.

    I hope he opens up again too, his kits were very good

    the kit parts can be bought at any true value hardware store, and float bowl gaskets from any industrial bearing supplier.

    Success!

    Bike starts strong, doesn’t die when I give it throttle before it’s super warm anymore.

    Still need to tune everything but it runs strong across the band.

    Need to do a better job bleeding the coolant - opened up the bleeder and got a nice spurt of nothing at all.

    Definitely need one more good day with the bike, but it’s shaping up well.

    Oh, and I used Rubber Renue on the carb insulators, so they’re the originals to the bike (cheap fleabay ones weren’t even close).

    25 minutes for each rubber and they were as pliable as new.

    All this time and I never looked inside the rad.

    This thing seems like it needs a good cleaning.

    What have people done here - just a CLR/distilled water soak? Or is there something else.

    Worth it to try and flush the inside of the system?

    Keeps temp fine while moving, but it does come up quick when in traffic/stopped.

    I recently used Evapo-Rust "THERMOCURE" to try to remove as much rust and corrosion as possible in a very corroded cooling system on another bike. It was the worst I'd ever seen by far. I did probably 4 distilled water flushes, 2 multi-day cycles of the evapo-rust, and then 4 more water flushes before adding coolant again. By the end I was getting clear water, but it was quite the ordeal.

    I'm not sure yours even looks that bad though. But if you're wanting to treat it, I'd suggest the evapo-rust stuff. I'm planning to use it on my VF later this year as I saved half the container for that purpose. It's like $30 for a bottle though, so it's not the cheapest out there.

    old school used baking soda in water, run it up to temp, then flush.

    The autofocus didn’t pick it up well, but all that white deeper in the rad are little crystals.

    Before I do anything I’ll stick a borescope in there for posterity’s sake (and so I can validate the $20 I spent on the cheapo one)

    Squirrel - makes sense, I guess you’re just trying to use an acid to clean out the calcium.

    Pure CLR is what I use to clean my rads. Has worked well so far.

    New school, take it off and take it to the radiator shop, go have lunch and a couple beers, come back and pick it up.
