where i can buy these conversion kit?

At 15:50 he says change what on the slide?

Hi. I have got an XF650 Freewind. Twin carbs is just trouble. I want to change to a single one (DR650). Is there a manifold available?

great job !!!!!!!!!!!!!!!

Hello I'm looking for to buy the mikuni carburetor or carburetor parts w3690z871 for arc gen welder .please help me find it if you can thanks

Why would you want 1 inlet instead of 2?

So.. I'm new to these carbs becuase I'm new to karting lol but I'm no stranger to carburetors like Holly, Edelbrock, Nikki ECt When I would adjust and tune my idle and mixture I would use a vaccum guage to see the highest vaccum in the engine when I adjusted the fuel mixture screw. On this 212 I'm thinking of drilling a hole to tap in a port right behind the carb to see of I can get a reading. Anyone else ever try this ?

Hi guys are you looking to do a similar set up for XTZ660 Tenere?

What I needed to know was idle lean and Rich adjustment, then mid range lean and rich adjustment, for how far to drop the needle and what difference it makes on the five clip settings, it was helpful to know that they started on the second from top clip stock

What if my carb will only idle with the choke on? Do you have any good starting points?

Cut the airbox rubbers?! Oh no, no, no,no,no.

hello how the gas apperate in it

Hugely helpful!! I didn't realize that the main jet was in the side. I thought that was just a bowl drain!!

I need majore help with my carb do you have a number so I can talk to you about it

Well, Thanks so much for clearing that up, now we know! Tuning a Mikuni Round Slide Carb IS ROCKET SCIENCE!

Any advice for 1978 rd250 ive had it ported ,

Thanks for making life easier for me with my Mikuni VM 36 on my 1979 Suzuki PE 250 N it’s dumping fuel out of the Overflow pipe so I’ll go ahead now and try and get it sorted 😉👍 And Best wishes to all in Australia 🇦🇺 from 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇬🇧

beyond good video, thank you so much!!!!

Hi I need a little advice I have dt 200 1986 my vile won't run unless the choke is on all the time

Qual o preço? Carburador mais falance

And do you also make one for the xt350 model? I have both a xt600 and xt350

What sort of blueprinting did you do for the manifold adapter to make sure of the fuel delivery from the carburetor?? Do you find there is any power loss or gain compared to the OEM carb

What's the price just for the adapter plate, without the hardware, for a Mikuni HSR42, I'm in Tucson Arizona. Thanks.

Hi I have vm 34's on my CX500 I'm about 10 full turns out with the idle screw ( one with spring around it ) she still seems seems to idle fast. She has straight through pipes. What do I do

Could I pleas confirm, as I have watch this about 10 times and I'm still not100% sure. Over 3 turns out I need a bigger or smaller pilot jet?

Did the VM 30 s for my Honda CM 400T rebuild. It starts ........awesome .....but with the choke levers down and and maybe for 3 or 4 min. it runs and quits. Now i gotta turn screws or something ?

thank you, legend.

Greetings! I am writing to you from Italy. I bought a used carburettor, which the previous owner bought from her. The carburetor is a HSR42 Specific for honda xt 600. I'm putting it on a yamaha xvs 1100. Could you please have an idea of ​​how to set the jets approximately? Now mount a 57.5 maximum jet and a 32 minimum jet.

Personal note 13:48 clip down richer clip up leaner

You have provided the best information for these carbs. I have been jetting for weeks! Midrange is still to lean in richest position on the needle. You mention go to the next size needle jet! Thank you!!!

how do you adjust the choke plungers when putting on a cable kit? the manual lever seems to move the plunger about 8.5mm

I need every jet and needle and slide made for vm24.....main size from 160 to 280.....and piolet 10 to 40 ......every increment in-between

how do you know what needle goes with what needle jet?

One of the best carburetor information videos I've seen yet explaining what to do and how it works great video

Do I have to change the needle height ig my bike is sputtering at half throttle

Hello. Nobody can officially anwser me or understand i have a question about when a mikuni is wide open. The cut air intake side is flush.....but un cut intake side has a bit of a lower hang.......so for max performance should i set them so the uncut side is just above the barrel? Or is it a bit lower for a reason? Thank you and hope you read this👍

Most comprehensive video on the subject I've seen yet. Thank you

My VM 13 came on a new bike in 2020, brass floats

Good video 👍

My bike will only rev up with the chokes on, it won’t rev with them off. It just goes blahhhhhhhttt and dies. The plugs have always been very sooty and black, which tells me it’s too rich. Since the Mikuni starter circuit is different from a standard choke, is it giving me more air to the mixture while it’s on and throttle opened? Which is why it can then rev with the choke on? With the throttle closed, it will barely idle with the starter circuit on. Been chasing down the tuning with these carbs for weeks. Air screw is almost falling out to achieve a rise in rpms; I have smaller pilot jets on the way. Any help would be greatly appreciated. Honda 400cc with Mikuni VM 32’s.

Thanks for this video. I run a 38 VM on my 83 Shovelhead. Seems to run ok . Just got to roll on the throttle!

Thx Tom, going good

Definitely explained it well massive thank you

How can I tell what size VM I have? Do I measure the inner diameter of the inlet spigot?

Good job

Hi would you have a vm to fit suzuki ts 250k 1973?

Thx for this helpful Video. Love the detailing, best regards feom germany 👌👌

Thanks for this useful information. I'm trying to tune a mikuni VM carb on a quad bike for a friend. He bought the carb online and slapped it on but it was extremely rich. It had a 200 main jet, I've gone down all the way to 130 and it's still a bit rich. The pilot jet was a 60,ive gone down to a 40 and it's still too rich so I need to get another set of pilot jets to dial it in some more. It seems clear that it's really not the right carb for that motor but it fits the stock boot so I'm working at it to get it right. Hopefully with the information in this video I can get it running well without replacing the entire carb.

Love your work mate, learnt more in these few minutes, than I have reading about carbi tuning, I've found there is so much miss leading in formation out there, I would of liked your input on setting float tang setting and its affects too, with my YAMAHA AG100 1973 that uses a mikuni vm20, it's to be set at 19.2mm, from carbi side of bowl gasket, no gasket in place, to the highest point of float, when in the upside down position, without pushing needle spring in.
