Carb Talk! Mikuni Round Slide VM's

Going over carb evaluation basics, what to look for and some advice on tweaking the jetting for performance.

Love this video, it’s exactly what I needed to be able to work on my own carbs

[@warrenford9947]

Very interesting and thank you. I have VM24ss on my kz650 and this video has cleared up a few questions. The fuel float levels are a pain which I solved using a 3D printer and making a clear float to use as a measure tool. Now the levels are very accurate.

[@MotoRestoFL]

Now, that's an idea! How'd you go about getting the 3D dimensions into the software? I don't know virtually anything about that stuff. I had a KZ650, a 1979 I think it was. My first brand-new bike. Had those carbs on/off a zillion times jetting/podding and with the of course, mandatory Kerker 4 into 1. Cheers.

I have a 1976 Kawasaki Z2 750 imported from Japan and having issues with the carbs. Thank you for this! Very informative

Thanks so much, very helpful

[@liveyourbestlife3785]

Thanks for the video alot of useful info. I have this set on a kz900 but I don't have an air screw on the air filter side, instead it has a fuel screw on the engine side of each carb.

[@scottwheaton9689]

The idle mix screws on engine side thru float bowls on came on 77 & newer kz1000 with 26mm mikuni’s regulating fuel flow & not air flow. The last yr 900 being the 76 kz900 came with idle mix screw on back side of carb closest to air filter regulating air only & not fuel.

Thank you very much, very educational. I have a 77 Z1000 which I hope to get going again soon..

I’m already subscribed. Which service manual do you recommend for a 77 Z1000?

[@MotoRestoFL]

@@jean-lucrombouts207 Thanks. You can find the original factory manual in PDF online, just do a google search. I grabbed a copy years ago, but I know it's out there. I purchased a clean copy in a spiral binder from a seller in Australia 6 or 8 months ago, it's the same as the factory PDF manual just clearer and I like paper service manuals over electronic. You can find them on eBay as well.

[@tfjack97]

Interested video, gives me an idea of how they work, but nothing like hands on. Did you make that rack or did I miss something? If you made it how about a quick video on it. Thanks Jack

[@MotoRestoFL]

I don’t quite understand making a rack, Mikuni did that. Do you mean tearing down a rack and reassembling? There are a number of those although spread within carb work on my channel like the Valkrie videos and I think some others. One never should I rack carbs unless it’s absolutely necessary and this particular rack is in good condition. Thanks for watching.

[@tfjack97]

No I was talking about the little stand maybe I should have worded it different, the stand that you had the carbs setting in to hold them straight up. Hope this cleared that up. Thanks.

[@MotoRestoFL]

@@tfjack97 oh gotcha. Yes I made that out of a cheap drill press vice. One that dates back to probably 1978 or 80. I haven’t seen many like it and it’s quite universal except for some carb racks that simply won’t fit well due to setup.

[@tfjack97]

Thanks for the info, I will try to get a better look at it and see what I can come up with. Thanks again for the reply.

[@wastingmymoneyonmotorcycles]

I don't suppose you sell those adaptor tools for using the float bowl drain to measure the float gas level with clear tubing?

[@MotoRestoFL]

No. They're easy to make. Find a jet even that screws into the drain and simply solder a small piece of copper tube available at any hardware and it'll work to hook up a clear plastic tube.

[@dshellymachine]

@@MotoRestoFL They are for sale on Ebay.

[@MotoRestoFL]

@@dshellymachine that’s cool. He asked if I sold them. Thanks.

[@thomasjakinsjr7024]

I need 2 leavers and a jet for these carburetors do you know where I could get them from

[@MotoRestoFL]

Not sure what you mean about leavers, you'll have to elaborate. As for jets, you can order them virtually anywhere. Which jets?

[@augustusczar7375]

How do you remove the needle?

[@MotoRestoFL]

That’s a bit complicated but the shaft has to be removed from the arms and then lift the slides and arms out then remove the arms from the slides and then the needles. Basically. There may be differences between these these types of carbs.
