    '99 Fuel Injection

    Is there anything particular to the '99 fuel injection that was a bust? Having talked with a few motor heads about EFI vs carburetors that are outside of the XX world, it's been recommended that ask about the initial fuel injection offering and if there was any particular problem(s) that were worked out in later years.

    Re: '99 Fuel Injection

    I have a 99/00 FI Bird with 128 000km and all is sweet. Fuelling, torque and power curve 'feel' clean and smooth. I did have to replace the ECU due to a code 25 knock sensor fault light (within the ECU not the knock sensor) but this can happen to later models. I did replace the fuel pressure regulator to the later slightly higher pressure unit as a precaution. There are slight differences in the 2001 'digital dash bikes' including an O2 sensor but I'll leave that part for the more knowledgeable Bird owners to expand on.

    Re: '99 Fuel Injection

    As I understand it it's mostly related to a test plug/connector Honda used during the build of the Fi that they then strapped in the harness and then corrodes, which can cause some more or less fun electrical issues. From what I've heard model 1999-2000 was more prone to suffer from it and that the later one's were better. But most Fi's suffer from electrical issues and there is a harness fix that takes care of it (hopefully).

    Iv'e got at carb and they are better in that way. But not perfect, and i did a bypass on mine so that the stator feeds directly to the rectifier, and the rectifier is wired straight to the battery terminals as it was melting plugs etc on the way when the recitfier went bad.

    The only real headache is the above stated loom fix. It was bit more prevelant on the 1st gen FI's as I call them. But even the later can have the issue. It's an easy fix for them all. Harness issues will show up on all bikes just because of age (the newest are 13 years old) how the bike was cared for will dictate it's tendency to give fits. But this site has a huge wealth of knowledge for the issues and fixes so I wouldn't be to worried about bugs.

    One small plus for the 99/00 is they have a separate baro sensor as an input back on the right rear corner. The newer FI's now have the Power Commander 5 as tuner option and it's improved tuning capabilities with the right packages. The 5 should be out sometime this year from what I have been told by Dynojet. Otherwise the bikes are identical with the exception or gauge pack and R/R mounting location. It's on the left side with the addition of another foot or so of wiring harness to move it to that side.

    Route 191 formerly Route 666 Some say that this section of the
    road has 1100 curves in 95 miles.

    Re: '99 Fuel Injection

    After reading all the responses and hearing from a friend/rider/mechanic that lives around the corner from me, I’m feeling much more confident that Fi is the way to go.

    Thanks, everyone.

    Re: '99 Fuel Injection

    The interesting thing here is that the bikes are now getting on but if we were talking about 10 years prior problems with bikes were a lot worse at this age. We now think an engine should go on for infinite miles but in the 70's, we were rebuilding at 20k max
