What does putting bigger jets in a carburetor do?

Bigger carburetor jets allow more fuel to enter the carburetor from the fuel tank. Usually, installing bigger jets alone is enough. Installing a bigger carburetor altogether is only done for major modifications, where you have significantly improved your bike’s air intake and fuel injection.

Do carb jets affect idle?

As far as jetting goes, the jet size will not affect idle, as the jets don’t come into play until the carb transitions to the primary circuit, unless the throttle blades are open far enough to expose the transfer slot. If this is the case, the throttle blades need to be closed enough to cover up the transfer slot.

Do bigger jets make more power?

A larger jet number means a bigger hole and more fuel. A smaller jet number has smaller holes and should be used if your engine needs to run more lean.

How do you clean carburetor jets without taking them apart?

To clean a motorcycle carburetor without removing it, you’ll need to remove the bowls at the bottom of the carburetor. Once the bowls are removed, spray some carburetor cleaner up inside, wait a few minutes, then spray again to ensure coverage. Then replace the bowls and start the motorcycle to assess how it runs.

How does Jet affect idle?

Main jet starts to affect the engine at about 7/8’s throttle and mainly controls WOT. If the main jet was missing, the bike would still idle fine and run fine up to about 7/8’s throttle. If it were completely clogged, it could affect idle as there is some bleed through at the needle (which the main jet feeds).

Does Jet needle affect idle?

Registered. The needle position has no affect on idle, it basically affects mixture around the 1/2 throttle range. If you need to change the WOT mixture you need to change the main jet, then change the needle to suit half throttle needs.

How do I know what size jet I need?

How do you tell if your pilot jet is too lean, rich, or just right? The pilot jet is sized correctly if the fuel screw setting falls between 2.5-3 turns out. The pilot jet is sized correctly if the air screw setting falls between 1-2 turns out, with 1.5 being the sweet spot.

Where are the air correction Jets on a Kadron?

The jets are carefully cleaned if they are the correct size for the application. We also measure the air correction jets, found at the top toward the middle of the carburetor housing.

What to do if your Kadron carburetor does not come out?

If it does not come out, the carburetor housing can be heated with a torch to facilitate easier removal. Once removed, a small ball bearing will be revealed underneath it. Don’t lose this ball! It is the secondary check valve, and serves a crucial role in the proper operation of the carburetor.

What kind of idle Jets does a Solex Kadron use?

Solex, Brosol, or Bocar 34-3, or 30/31, use a 60 idle, and a 50 power jet (also called the “Pilot Jet). This seems wierd, but it’s because of the construction of the idle and progression circuit (most guys have never ever bothered to look at it closely), which uses both jets (Combined area), in conjunction with 2 big idle air bleeds.
