Carburetor Jetting Is Useless Without This First
Don't miss a thing! Subscribe Now! http://bit.ly/2kzUdzB An integral part of the jetting process is setting the float height in your carburetor. If the floats are allowing the incorrect amount of fuel into the float bowl, it will alter the jetting of your machine. -Cameron ReVive Moto: https://www.revivemoto.com Need Tools? https://www.amazon.com/shop/cameronniemela Facebook: https://www.facebook.com/ReViveMoto Instagram: https://www.instagram.com/cameronniemela Tools I Use: Scissor Lift: http://amzn.to/2xH1pkn Dewalt Impact Driver: http://amzn.to/2wDxAEz Tire Levers: http://bit.ly/2wX88JX Spoke Wrench: http://bit.ly/2vBtn0c Tire Change Stand: http://amzn.to/2wPFIlz Wheel Truing Stand: http://amzn.to/2wPC7Ea Crankcase Splitter: http://amzn.to/2wPTCV0 Circlip Pliers: http://amzn.to/2gn4u5G Exhaust Spring Puller: http://amzn.to/2wfiUKx Torx Bits: http://amzn.to/2wlHcBj Allen Bits: http://amzn.to/2wlBTlh Torque Wrench: http://amzn.to/2vGzz6x Impact Screwdriver: http://amzn.to/2iDBwzg Bel-Ray Waterproof Grease: http://amzn.to/2iBXRNz Y Handle Tool: http://amzn.to/2wQ1Axt Bearing Puller: http://amzn.to/2wPOn7x Cleaning Supplies: Aluminum Cleaner: http://amzn.to/2wld1dn Degreaser: http://amzn.to/2voFxxx Camera Equipment: Canon 80D: http://amzn.to/2vlPXOk Flexible Tripod: http://amzn.to/2vmj9F3 Tripod: http://amzn.to/2vm6NfT Looking for a way to support the channel?

Mikuni Carb series #4 How a Mikuni carb works.
Ever wonder how a carb works - I'll explain it.





basic carburettor adjustment (tuning) 4 stroke, and how it works.
In this part 1 of two video i am showing you where the different parts and adjustments are on my old honda with a new carbie works on most small carbies. i will show you what to look for when tuning your carbie! please enjoy and watch my other videos. :D i will make a part 2 tomorrow! this one is on my honda xl100 1974 classic honda style, but is the same, for classic and new yamaha kawasaki suzuki and all small bikes pretty much. motorbikes and cars are simular. how to adjust the fuel air mixture and the idle speed. riding it to test the tuning.





How Motorcycle Carburetors work and how to tune and clean them
Here's a link to the kind of carb cleaner I like best (it IS the best) http://amzn.to/1rsKle5 Check out my newest carburetor video (it's even better!). → https://youtu.be/Rzec6VJQFCg Follow me on Facebook → https://www.facebook.com/briansmobile1 Follow me on Instagram → https://instagram.com/briansmobile1/ Check out and/or Donate to my favorite Charity here (or ask your boss to!) → http://www.g1dfoundation.org/ hey... awesome video..nicely explained ! just one question. Please do tel me wts AIR NEEDLE and LOW JET used for again. ? i mean how and what do they work? thanx :) Reply · The air needle is like a transitional restriction to increase vacuum pressure and tapered to prime the main jet flow gradually to ramp up fuel flow from the idle/low circuit to the main circuit. Think of the circuits like gears or stairs. The needle covers transition between 3rd gear to about 5th gear on a six speed. It overlaps basically. Fuel is getting by it from the idle/low- on through to where it's completely out of the way of the main jet and the main jet fuel flow is roaring like the straw/compressor example. Without the needle the carb would work, but not as smoothly through middle throttle (where most people ride and have the most fine input or throttle roll back and forth. The low jet is like second gear on a transmission. You can shift from 1st to 3rd, but again you risk stalling and it won't be as smooth. Also there isn't really the mechanical inertia to carry the process on like you have with a rolling vehicle with a flywheel on the engine and the wheels turning. The pistons still create vacuum every other time they go down, but air just doesn't have the punch that steel does when in motion. The circuits in a carburetor have to be there or you would have a limit on RPM range. An idle jet can't deliver enough fuel to really scream, and the main jet couldn't go slow and would be VERY hard to start because the engine would have to be spun up really fast. So you have usually four or five circuits (I want to say jets, but their physically different) that get air flow like stairs as the throttle opens. They are typically 1. Starting circuit (choke on) 2. Idle circuit 3. low jet 4. Jet Needle 5. Main jet.
