Other Air Intake & Fuel Delivery
About Other Air Intake & Fuel Delivery
This category holds intake and fuel delivery parts that do not fit a narrower group. The sample listings show a wide spread, so it helps to know the main types you will find here and what each one does.
Fuel injection modules, such as the Power Commander 6 listings for Polaris, Yamaha and CFMOTO machines, adjust the fuel an injected engine receives, and some also adjust ignition. They are typically used after an exhaust or intake change, and the listing says which model each one is for. Choke plunger kits and reed sets belong to carbureted machines: the plunger is part of the cold-start choke, and reeds are the one-way valves on a two-stroke intake, which can wear or crack. There are also snorkel kits, air filter cages and VForce reed valve systems for particular models. Because the category is mixed, search by part name and pick your machine in the Ride Finder at the top of the page.
Brands here include Mikuni, S&S Cycle, Dynojet, All Balls and SW-Motech. Related groups are Air Filters, Carburetor Parts, Fuel Injectors and Fuel Filters. The whole group is Air Intake & Fuel Delivery.
FAQs on intake and fuel delivery parts
What does a Power Commander fuel injection module do?
A Power Commander is a plug-in module that adjusts how much fuel a fuel-injected engine receives, so the mixture suits changes such as a new exhaust or intake. Some versions also adjust ignition timing. Check that the listing is for your model and follow the maker's setup instructions.
What do reed valves do, and how do I know they are worn?
On a two-stroke engine, reeds are one-way valves that let the fuel and air mixture in and keep it from flowing back. Worn, chipped or cracked petals can cause hard starting, a poor idle or weak low-speed power, so inspect them when the engine is apart.
What is a choke plunger for?
A choke plunger on a carbureted engine enriches the mixture for cold starts. If the plunger sticks or leaks, the engine can be hard to start cold or run rich when warm. A plunger kit replaces the worn parts.
Does a snorkel kit make an ATV waterproof?
No. A snorkel kit raises the air intake so it is less likely to take in water, but other parts, such as the vents, the electrics and the drivetrain, still have limits. Follow your owner's manual for water crossings.
