@oneupmoto: Good To Know: If your needle doesn’t have a clip, you can shim it with fuel mixture screw washers. 1-2 shims will fix any flat spots, bogging, or hesitation in the mid range. The needle influences almost all throttle positions, so thoroughly test the full range after each adjustment. It’s often not enough when tuning to just change jets, the needle position usually needs to be changed as well! Most carbureted bikes have these and this is an essential part of tuning them 👌 #motorcycle #mechanic #automotive #fyp #tuning

How do you know when it needs to be leaner or richer

nickydabob :

How can i tell if its the fuel/air screw or the needle?

NSS Concepts :

I remember by “lower - lean, rising - rich”

drew.junior :

this my sound dumb but i need help bad will this fix my idol problem when they choke is all down it runs great but when i flip the choke up it rpm bombs idk what to do

ride4style :

You do this after finding your main jet and configured the air to fuel ratio right?

glenjohnson6501 :

As a professional who has worked on literally thousands of carbs in my career, in most cases, moving the clip on the needle is the last step in setting up a carb. Moving the clip one position is the equivalent of changing the main jet 3 to 4 sizes. If you are tuning you carb for mild to moderate performance packages it is always better to change main jets to accomplish what your after. Most the time you will get what you need with a simple main jet change. Once you move that needle clip then you have to start over selecting the proper main jet for your application.

I dont have a clip

Tph_70🍃 :

I have malossi sport 70cc, polini evo2, E14 malossi filter, 17,5mm delorto and 85 main jet and it stops going faster after 70kmh so do i need it leaner or richer

kubeo :

I have this problem where the "barrel" that holds the needle gets stuck on the idle screw because i pull it too high , the barrel just keeps rotating and nothing holds it in place , is this because of the carb construction or am i missing something ?

dvsnty :

Leaner is meaner, richer is $

Black_Piaggio :

how to perfect tune it?

Brian Gibson :

01 Honda vt750 seems perfect but I know it’s lean incut pipes still has stock setup I let off an snap back in throttle when I’m in high rpm an it pops an takes a sec to come back if I let off an slowly roll back in it comes back without popping could I raise my needle an drop clip to help this

6billz Stunts🪖🏍 :

So which gives more power

JensYam :

throttle pos. rich/lean problem area ajustment.. Idle - 1/3 = pilot jet 1/3-2/3 = nedle jet WOT = main jet..

PK Repair :

mijatovic :

what is going on with GSXR 50

Muggi :

So I’ll just use my needle if I don’t have any jets?

gribens :

air screw is to tune pilot jet, just find near full 2 turns in air screw and needle for main jet, we simply start at the top to mid clip/lock, if its still lean, just change the clip going down, and if its still lean when its in the mid, put bigger main the put the clip back at the top then same process

wickednative89 :

how do u clean a gummed up carb

cocofanto :

did bro just cut a carb in half ?

714esko :

This is how to tighten loosen the throttle?

dhemver. :

How do you fix overflow problem? no matter how many time I adjust the floater it stills overflow

. :

why has my needle snapped in half like 4 time already
