Description

Some of the NICHE product categories include cylinders, brake pads, axles, off-road mirrors, and drive chains. Let NICHE components fix your machine today! A carburetor’s job is to supply an internal combustion engine with air/fuel mixture A carburetor works by mixing air and fuel to allow for internal combustion. ATV Carburetors: Most ATV carburetors use a simple design. They have a vertical air pipe that’s strategically located above the engine cylinders. The vertical air pipe is then joined to a horizontal fuel pipe (at the narrowest part of the venturi) which allows for the passage of air into the engine’s inlet manifold. The inlet manifold, also called the intake manifold, is part of the engine that supplies the air/fuel mixture to the cylinders Motorcycle Carburetors: Regulate the flow of air through their Main bore (Venturi), this flowing air draws in fuel and the mixture enters the engine via the intake valve.Turning the throttle on a motorcycle handlebar does not directly control how much fuel enters the engine. The throttle controls how much air is allowed to flow through the carburetor, and the flow of air is what controls how much fuel is also fed into the engine Niche Industries, headquartered in Metro Detroit, is a leader in manufacturing and distributing replacement parts for the most popular powersports machines.

  • Not a direct replacement.
Does not work with the factory throttle cable; also has different size fuel inlet. It may work if you changed the fuel line and used a Niche throttle cable. I returned it because I wasn't up for the battle. TRX250EX

  • DOES NOT FIT
Does not fit a stock 2008 Honda TRX250EX like the description specifically says it fits. Trash.
