This write up will highlight how to change the main jet on your carburetor without removing your carburetor from your machine. In my case, upping the main jet is all that is needed to compensate for an aftermarket pipe and filter. Some machines may require upping the main and playing with the needle. For now, we'll just deal with swapping out main jets.
Depending on how your machine is set up, you may want to remove the fuel line for easier access to the carb.
Pic 1- Loosening the carb...engine side. I had the airbox removed for another project, but it did makes things easier. If you don't remove your airbox, make sure you loosen the clamp on the air box side, as well as the engine side.
Pic 2- Once that's taken care of, slowly rotate the carb 90 degrees so the bottom of the bowl is facing you. Do this slowly so you don't kink or tweak any cables or wiring that may be around the carb. It's also a good idea to put down some rags or paper towels to collect any fuel that will spill out of the bowl.
Note: The dump screw on my carb didn't have the hose attached to it. Usually, you can shut off the fuel at the petcock, open the dump screw and catch any gas that drains from the carb. Without the hose, I used the paper towels to catch any gasoline that came out when I slowly loosened the 4 screws holding the bowl to the carb body.
Pic 1- Remove the 4 screws holding the bowl to the carb body. Some fuel may spill out here. Once you have the screws removed, pull off the bowl. Next, carefully unscrew the main jet.
Pic 2- While you have the bowl removed, clean it out with some carb cleaner. If you look closely, you can see some stuff in the lower righthand corner of the bowl.
After the bowl is clean, it's time to install the new jet. Install the new main and snug it up. Don't crank the thing down too tightly; you don't want to damage the carb body! Just tighten it until it's snug. Once you have the jet in, you can reinstall the bowl. I used a little anti seize on the screws to facilitate removal in the future.
Button everything up, start the quad and take it for a ride
