Face it, the carburetor-that great hole with its belly of gasoline and another bunch of smaller holes, a maze of passages, some brass pieces and maybe a few wires-is more dead than the two-stroke. Fuel injection is taking over. FI is here for two reasons: First and most importantly, the cost. The electronics that control the system have dropped in cost and size to where they are price competitive, often even less expensive compared to a carburetor. Second, the control that can be programmed into the FI systems can give all the advantages necessary for today's applications, everything from delivering flawless throttle control all the way to meeting ever-tightening emissions standards on non-competition bikes.You can hardly find a car or truck manufactured in the last 20 years that isn't fuel injected, so the writing has been on the wall a long time that the switchover was going to happen with motorcycles. It has been going on with the street side of motorcycles for at least the past 10 years. When spy shots from Japan first began showing FI motocross bikes, the rumor mill went into full effect, claiming fuel injection offered less power, no snap, poor throttle response, less rpm, stalling, clogged injectors and inexplicable electronic failures. Now that we've been riding more popular brands producing FI bikes for the last couple of years, those fears have largely diminished because the high performance is there. Sure, the first Cannondales and ATKs that boasted then-revolutionary FI systems had issues. But remember, that was a good decade ago. Shortly thereafter companies like Gas Gas and Sherco made the switch on some of their higher-end four-strokes. Next Montesa, which was actually an arm of Honda, made a bold step with the 2005 Cota 4rt in the trials world with a four-stroke battery-less FI system, which is now commonplace.
