what year did the r6 become fuel injected

2003 was the first year the Yamaha R6 came with fuel injection

The review is below

The 600 Supersport wars heating dramatically in 2003 thanks in part to Yamaha who just introduced today 2003 YZF R6. Initially launched in 1999, the race winner receives R6 serious updates for 2003 and will probably be a competitor for the coveted AMA 600 Supersport crown.
More specifically, the 2003 is “ninety-nine per cent”, according to Yamaha, with a new chassis, engine fuel injection and new bodywork.
The chassis must have put a lot of welding robot to the factory on a job, since it incorporates “controlled filling aluminum die-casting” technology to build a large part of the frame and swingarm. Today, the company can tune large pieces of cast aluminum chassis as a section and not weld aluminum and several parts as Yamaha did with the old framework R6. The lack of welds and less real evidence tying together the framework must be inherently stronger – Yamaha argues that the framework is fifty percent stronger in terms of lateral stiffness than in the past. And lighter. The whole machine is eight pounds liger that modèle’02, 357 pounds, sec.
And even if it is stronger or lighter, the new process is a yield surprisingly beautiful finished product, devoid of any welds, overlap and other sections cobbly manufacture looking scars. Both chassis and swing-arm could easily hang in any gear-head garage as an example of fine-art motorcycle.
To improve traction and comments, the new swing-arm is ten millimeters more than the former, Yamaha continues to build on the “long arm” philosophy of the original R6. The engine is still highlighted a member of the chassis.
The top of the still inclined engine before the R6 series 99-2001 carburetors are discarded in favour of gas-body style electronic injection on the 2003 model. Thirty-eight bodies grow millimeter gas fuel to the engine, replacing thirty-seven millimeter carburetor. The AirBox is larger, more effective in designing courses and includes air dynamics.
Under the R-1 style fuel injection (piston suction style), 2003 R6 engine is refined to improve the efficiency of admission, while the lowest in a room bottles and cases assembly, Yamaha say worked hard to erase pumping and friction loss. New crankshaft, rods, bearings and revving make it easier, while lumpier cams (which are not sacrificing R6 strong mid-range just for a big dyno numbers at the top), new lighting and new pistons help increase power. Ultimately, 2003 R6 argued with a 123 horsepower pressure AirBox, three horses over 2002.
Everything is pushed through a ratio of nearly six gearbox, stacked to create a lower CG.
The cooling is provided by a GP-style curve and a radiator cooled by liquid oil cooler.
For the suspension, 2003 R6 is a 43mm front fork with adjustable pre-load compression and rebound. Brakes are discs floating 290mm at the front with four-piston calipers.
Besides the beautiful and improving Yamaha engine chassis equipped in 2003 with new R6 bodywork recalls the R1. The lighthouse design is now described as “double Gatling-style while the rear lamp is a double-bulb LED design.
