About the Honda CBR900RR

The Honda CBR900RR, also known as the "Fireblade," is a sport motorcycle that was produced by Honda from 1992 to 1999. It was the successor to the CBR600F2 and was eventually replaced by the CBR929RR and CBR954RR.

The CBR900RR was a popular choice among sportbike enthusiasts for its combination of power, agility, and handling. It featured a liquid-cooled, inline four-cylinder engine with a displacement of 893cc. This engine was capable of producing around 115 horsepower and 73 foot-pounds of torque, which made it one of the most powerful bikes in its class at the time.

One of the key features of the CBR900RR was its lightweight frame. It weighed just over 400 pounds, which made it highly maneuverable and easy to handle at high speeds. The bike also featured a fully adjustable suspension, which allowed riders to fine-tune the handling to suit their specific needs.

The CBR900RR was known for its sharp, responsive handling and excellent stability, thanks to its carefully designed chassis and suspension setup. It also had excellent braking performance, thanks to its dual front discs and single rear disc, as well as its responsive ABS system.

In terms of styling, the CBR900RR was a sleek and aggressive-looking bike. It featured a sharp, angular design with angular headlights and a distinctive dual-exit exhaust. The bike was available in a range of colors, including red, yellow, and black.

Overall, the Honda CBR900RR was a highly respected and popular sport motorcycle that offered a great combination of power, agility, and handling. It was a favorite among riders looking for a bike that was capable of delivering a thrilling riding experience on both the track and the open road.

The Honda CBR900RR was equipped with a Keihin CV carburetor, which is a type of constant velocity carburetor that uses a vacuum-controlled slide to control the amount of air and fuel that is drawn into the engine. The carburetor on the CBR900RR was composed of several key components, including:

• Throttle valve: This is a butterfly valve that opens and closes to regulate the flow of air into the carburetor.

• Main jet: This controls the flow of fuel to the carburetor. It is located in the center of the carburetor and is adjusted by screwing it in or out.

• Pilot jet: This controls the flow of fuel to the carburetor at low throttle openings. It is located near the bottom of the carburetor and is adjusted by screwing it in or out.

• Needle jet: This controls the flow of fuel to the carburetor at medium throttle openings. It is located near the top of the carburetor and is adjusted by raising or lowering it.

• Needle: This controls the flow of fuel to the carburetor at high throttle openings. It is located near the top of the carburetor and is adjusted by raising or lowering it.

The jetting of a carburetor refers to the specific sizes of the main jet, pilot jet, needle jet, and needle that are installed in the carburetor. The jetting of a carburetor is important because it determines how much air and fuel is drawn into the engine at different throttle positions. If the jetting is incorrect, it can cause the engine to run too lean (not enough fuel) or too rich (too much fuel).

The jetting for the Honda CBR900RR is specific to the individual bike and can be affected by a number of factors, including the altitude and temperature at which the bike is ridden, as well as the type of fuel that is used. It is generally best to stick with the manufacturer's recommended jetting unless there is a specific reason to make changes. If you do need to make changes to the jetting, it is important to do so carefully and gradually, and to make sure that the carburetor is properly balanced.
