RICH or LEAN mixture. Symptoms and consequences. How to carburet a motorcycle. Kawasaki ZZR 1100.

ATTENTION!! There is a typo in what I said starting at minute 15:38, what I am saying is that if the screw is closer to the engine block inlet what regulates is the air, when in reality it is just the opposite. That is, if it is in that position what is regulated is the fuel mixture, therefore, if the screw is closed (clockwise) what is being done is causing less mixture to pass through, which would impoverish it, leaving the carburetion "finer" or "lean", and if we loosened the screw, what we would be doing is allowing more mixture to pass through, which would be "enriching" the carburetion, leaving it "fatter" or "richer". If the richness screw is located before the slide valve, that is, if the arrangement were first the richness screw, then the slide valve, and finally the engine block inlet, the richness screw would regulate the air intake. Therefore, if we close the screw (clockwise), what we would be doing is reducing the air, which would enrich the carburetion, making it "fatter." If we open the screw (counterclockwise), we would be letting more air in, which would make the carburetion leaner, making it "leaner." Another typo is the pronunciation of the word for the ratio of air to gasoline portions, which should be 14/1 and is called "STOICHIOMETRIC." In the video, I say "sketiometric." Sorry, I was a bit confused, hahaha. In this video, I aim to clarify some questions about the difference between a "RICH" air/fuel mixture, a higher proportion of fuel than the stoichiometric ratio (14.7 parts of air to one part of fuel), which would mean a lambda factor less than 1, and a "LEAN" mixture, which would mean a lower fuel ratio than the stoichiometric ratio (a lambda factor greater than 1). I will identify the symptoms and consequences of each, and then adjust the carburetor accordingly using the "richness screw" or "pilot screw" on the carburetors. This video is part of a series on the comprehensive maintenance and overhaul of the legendary Kawasaki 1100s from the 1990s. The ZZR 1100, Model C from 1992, 150 hp, with a top speed of 300 km/h, which once won the AVE (High Speed ​​Train) in a Madrid-Seville race. And its touring sister, the GPZ 1100, with 130 hp, share the same engine, but the latter lacks ram-air and has slightly smaller carburetors, giving it less racing-like handling. If you want to listen to it in its original Spanish version, here’s the link to the video:    • Mezcla "RICA" o mezcla "POBRE". Síntomas y...   I highly recommend watching the video made by the master "Pierre..." on understanding how carburetors work and how to regulate the mixture, not only at idle and in the first eighth of the throttle's travel, but also in the different quarters of the travel, where, in addition to the richness screw, the slide valve, the needle and its adjustment, the diffusers, etc., come into play.
