Lol... I just tripped a code too when I reinstalled mine. Not sure what I did, wish I knew but itís easy to clear. First of all you need to know if they disabled the air injection, I would assume they did, if they didnít youíll need to leave the pump plugged in or get a eliminator to plug in or jump it with a resistor. Any way, another member on here had a good post on how to clear the codes and I did what he said, but here it is:
You need to satisfy the following requirements, start bike, let it idle for 30 seconds, drive bike for 10 minutes, 5 of the minutes need to be above 25 mph. Then repeat three times in a row.
The following is what I did and it worked the very first time, youíll need a good 30 mile stretch of road, I live on the edge of town so I used the freeway at night (no traffic) here goís:
1.Pulled over on the on ramp and shut bike off.
2. Started bike and let it idle for 35 seconds ( need 30 but i was counting in my head)
3. Drove bike between 50 and 60 mph for 12 minutes ( need 10 but i was using the clock on the dash, gave a cushion)
Then pull over and do it again, 3 times total. Then shut the bike off and when you turn it back on, poof, codes are gone if the problem is non existent.
Hope that helps!
