check for codes.
To check for trouble codes turn the ignition switch to run for three seconds (one second pause after the fuel pump stops running) and then turn the switch back to off for three seconds. Repeat this process again. Now turn the switch to ignition and wait for about 8 seconds and the check engine lamp will start flashing the codes. If there are codes present the light will flash rapidly (about three per second) then there will be a 2 second pause with the lamp off. The lamp will then flash one or more times to indicate the first digit of the trouble code. It will be on and off for about 1 second. Count the number of times it flashes for the first digit of the trouble code. Then there will be about a 2 second delay then will flash again for the second digit. After flashing the second digit there will be a 2 second delay and additional trouble codes will be flashed. Write down the numbers and when they start repeating themselves the trouble code transmission is completed. All trouble codes consist of two digits.If the lamp flashes only the 3 flashes per second there are no trouble codes present.
let me know what you find.
after re-reading your question, it seems this is not your personal motorcycle.
are you a shop or professional mechanic expecting to be paid for this repair?
so if this is your personal bike, why did you say "the bike at for 2 years and the bad gas ruined his fuel pump."
one would say "his" if it belonged to someone else.
let me save us some time. I don't help shops. I help people who would like to learn how to fix their own bike.
I am going to OPT OUT.
that will open the question for anyone else who would like to answer your question.
best of luck with his problem,
