Carburetor Tuning Basics: Changing Your Carburetor Jets on a Mikuni Carburetor
I'm working on a new project we're calling "The Motorhome Experiment" at For years my wife has been riding with me on our motorcycle, even though she's not a huge fan, and now I've proposed selling everything and hitting the road in an RV. She's giving me a year, I think it'll be more...come check us out at The Motorhome Experiment channel on YouTube at Carburetor Tuning and Carburetor Jets - This video shows how to replace the main carburetor jets on a Mikuni carburetor. It is a very simple process on the Mikuni and can be done on other carburetors with a little effort and some basic tools. Figuring out what carburetor jets you actually need for your motorcycle is part art, part science. It can be done with proper testing equipment or by trial and error. Drop in a new carburetor jet and go for a ride. Drop in a bigger or smaller jet and go for another ride and compare the performance. Not that difficult really. If you live at higher elevations your jetting will be much different than those who live at sea level. All of those things effect performance. Engine modifications will also effect what jets you need because your engine will require more or less fuel depending on those mods.
