"Easy. First thing to do is locate your diagnostic test plug under the
seat. It's an empty four pin connector. If you're looking at it with
the pins facing you and the locking tab at the 12:00 position, the
pins are numbered as follows:

Pin 1 -- upper right corner
Pin 2 -- lower right corner
Pin 3 -- lower left corner
Pin 4 -- upper left corner

With the ignition switch off, install a jumper wire across pins 1 and
2 in the diagnostic plug.

Turn the ignition switch to the ON position and wait approximately 8
seconds for the check engine light to start flashing.

All trouble codes are sent out as a series of flashes. To retrieve the
first digit of the code, simply observe the number of times the lamp
flashes.

The transmission of a trouble code is always preceded by six rapid
flashes (about 3 per second). This transmission is followed by a 2
second pause in which the lamp is off. The lamp will then flash one or
more times to indicate the first digit of the trouble code. The length
of time that the lamp will be either on or off when indicating a
trouble code is about 1 second in duration.

Following the transmission of the first digit in the trouble code,
there will be another two second pause before the second digit is
transmitted.

After the second digit is transmitted, there will be another 2 second
pause. After the pause comes another intermission (six rapid flashes)
after which the next stored code is transmitted in the same manner.
Once all the trouble codes have been displayed, the sequence will
repeat.

If all you observe is the rapid flashing, then no trouble codes have
been stored.

When done, turn the ignition key off and remove the jumper wire.

There is no way to clear trouble codes using this method. The only way
to clear codes without hooking the bike up to a computer is to take
the bike through 50 start and run cycles (start engine, run for at
least 30 seconds, shut it off).
