Is This Dirt Bike Running Too Rich or Too Lean?

Adjusting the carburetor on my 110cc pit bike and I'm not sure if it is running too rich or too lean...

Turning the air screw out increases the amount of fuel added, turning in decreases the amount of fuel added. If your air/fuel mixture screw is out more than 2 turns you need to get a bigger pilot jet, if your screw is at 0 turns out and still doesn't run right you need to lean the pilot, hope this helps! Enjoying the build so far! 😎

Clean that carb out real good too brother, one little piece of dirt can be a problem

Depending on where the screw is located will tell you whether you have an air/fuel screw(air filter side) or a fuel/air screw (intake side). Air/fuel screw is turned in for more fuel, and out for less. And it’s the opposite for fuel/air screw. The general range of either screw type is from 1/2 to 2 1/2 turns out from being seated.
Based off your video it looks like you have an air/fuel screw. If your more 2 1/2 turn out with out correcting the issue you need to drop a jet size.
Rule of thumb- too rich will bog then pick up, too lean will hunt for idle, or it will bog and die, sometimes will only run or rev with choke. Hope that helps lol

Definitely running lean after your adjustments make it richer

What I found with the mikuni carb on my dr350 is it bogs bad unless you use the factory air box and the super dense factory foam filter. It has something to with the vacuum pressure being higher with a more restrictive filter and atomizing the fuel better

Check out the floats. My bike had that same problem you can by a factory tune one of slightly bend that one.

Yo it’s running lean a rich bog would sputter and rev up once the gas clears out the cylinder lean won’t rev at all

[kaiden]

Yes readjust the carb now and u should be set

Quit playing with that carb get a mikuni vm22 please rubber boots generally earnt the best the top end could be making to much vacuum for that carbs application
