The truth is, in some cases (depending on the carburetor style) you may NEVER get all of the bugs out of your carburetors response at certain transitional phases throughout the throttle. Most of the time people battle between poor idle responses such as hesitation when the throttle is flipped or choppy breakups throughout mid-range throttle. This is more common on much older carburetor systems that may not use systems like accelerator pumps or air-cut valves.
"Finding the sweet spot between poor throttle response and poor mid-range to wide open throttle is key"
There are hundreds of different posts on carburetor jetting that involve scientific theory's, algorithms, charts and math that can be very helpful yet confusing when setting up the fundamentals or "starting point" for what needs to change inside the carburetor. The way I dial in carburetors is not the ONLY way... It's just what works best for my brain.
For example I found this pretty nifty write up from the guys over at CafeRacersUnited.com
They have a cool way of calculating jet sizes that I can agree with!
What I don't advise you to do is to go out and spend 100$ or more on a fancy staged jet kit and expect it to be a sure-fire bolt on fix for all things carburetor. Often times it can end up leading you into deeper water with overly drastic jet and needle changes that simply are just not needed. Don't get me wrong, I have heard plenty of people swear by certain set ups from aftermarket companies as the "wham bam thank you mam" fix for their bike's application. So To that I say congratulations on finding the perfect fix....but for most people, it's just not that simple. In some cases I do believe kits like these can serve it's purpose as a general platform to start on.
"The one thing that isn't factored in with jet kits is your physical location. Meaning that If I live in Colorado and buy a high dollar stage 2 jet kit. Then Tommy boy buys that same stage 2 kit but he is located on the east coast beaches of Virginia. There will be very different results."
That being said.. LET'S BEGIN!
One of the quickest most useful tools you can use to diagnose any carburetor problem is the choke system designed with the bike. Once you have installed the pod filter(s) and have evaluated how the bike is responding to them, you can use the choke to determine what helps the problem spot.
Example 1: New pods are on and the bike seems to idle "okay" but as soon as any throttle is given the bike shudders and shuts off or it has a bad hesitation and shudders/backfires until you increase the throttle more. If you apply the choke during the throttle operation what happens? Does the bike's RPMs suddenly pick up and respond better to the throttle? Or does it get worse and shut off instantly because of the richer mixer you added. If better is your answer, than start here. An increase in either the idle jet or main jet needle would be the first to increase.
There are three different styles of choke systems that Honda uses on their bikes, ATV's and scooters. Although they are different they are all serving the exact same purpose, which is to RICHEN UP THE MIXTURE entering the combustion chamber.
