I was just getting started with getting familiar with these carbs when you bought this one and here 40 some odd years later I am still learning, and thanks to you sir I am proud to say I learned something new today. It is a wasted day if you don't learn something new when given an opportunity. Well spoken and explained clearly. I'll be looking forward to more of your videos as I am an old Motocross,Enduro, Rider of trails,etc and I am restoring several vintage Bikes both 2 and 4 stroke so I'll be checking to be sure. Thanks for your video. I'm going to grab some air in the meantime if the jets are the problem and I am almost 100% sure it is after your demonstrating with the pen vise which I have got to get one of those for sure now,Thanks again,Take care.
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.
How can you tell which type/model Mikuni carb I have? My mechanic told me I have an HSR 42 carb, but I am wondering is my designator is further broken down into a VM 28/486. What does that designator mean?. I am trying to find a suitable pilot needle (a 25) that will fit it. Thx
This is by far, and without a doubt the best explanation of a Mikuni carb I've seen so far

Very very good explanation, thank you so much.
Thank you, a lot of technical info on these mikuni carbs...well done!
Great videos. Thanks. If you change the speed of the video to 1:25x it sounds like Johnny Cash made this video 😂
You Sir are a fine teacher. Thank you very much.
thanks v.m. Sir
Thanks!
