Well I was headed out to work this morning and right away after start my engine light came on. I shut the bike down and restarted and the light went away until I got half way down the block. So I had to turn around and take the WR in.

If there anyway I can check the code it's throwing without taking it into the dealer? How long is the warranty anyhow? I bought it in September 2008.

quote from link-


Go to the data link connector that is located on the left side just under the edge of the seat. Remove the rubber insert. There are four pins inside. Looking at the connector with the locking hasp pointed down. The pin orientation is such that pin # 1 and pin #2 are both on your left. See below:


#2 #3

#1 #4
lock

With the key and ignition off, connect pin #1 and pin #2 with the home made jumper. Make sure you do not touch the other pins! Then turn the key and the ignition on. Do not start the bike. The engine light should start to flash:

If it flashes many times (about 10 or 11, to fast to count for me) very fast, then there are NO trouble codes.

Otherwise there will be 6 quick flashes at 3 per second and this is an intermission.
Then there will be a 2 second pause
Then count the number of one second flashes separated by 1 second pauses and this will be your first digit.
Then there will be a 2 second pause
Then count the number of one second flashes separated by 1 second pauses and this will be your second digit.
Then there will be a 2 second pause
Start back at intermission of 6 flashes…………..and so on……..

This will continue until you turn off the ignition and the key and remove the jumper. If you remove the jumper without turning off the ignition the engine light will continue to cycle trouble codes.

If you have a trouble code and then you correct the problem that created the code. The bike will automatically clear the codes after 50 start and run sessions of at least 30 seconds or more. Until then the code will remain even if the problem is fixed.

Trouble code list:
11-TPS
13- O2 sensor
14-ET (engine temp)
15-air intake temp
16-battery voltage
21-exhaust actuator
23-front injector
24-front coil
25-rear coil
32-rear injector
33-fuel pump
35-tach
36-fan
44-bank angle sensor
52, 53, 54, 55- ECM failure
56-cam sync. Failure

Keith, I would be willing to bet you have a code 21 which is an exhaust actuator failure, just as I did on my 08 XT. Take a flashlight and shine it down at the cable on top of the muffler and perform the actuator cycle test. If the cable does not move, your actuator is shot. You don't even have to remove the airbox cover to check it that way, very simple.

Please check this thread:

Thanks for the replies guys. I have been too busy to even check here let alone check out the bike but I will keep you updated.

I'd be surprised if it is the exhaust actuator. I lube the valve at every oil change.

Alright Motorbike, you win. Code 21 it is. Now to see if I'm still under warranty. If not I'll just wire it open and get a new CPU from Eric Buell racing.

just had the exhaust actuator changed a couple weeks ago, hopefully i don't have to worry about that one for a while but also had the reflash and i can tell a big change on performance and heat issue not nearly as bad.

Keith mahoney, I forgot how much we bet, $100 wasn't it? Haha!

A new actuator is $164.00 and an Erik Buell Racing race ECM is $250 but it is your bike and your money. Please let us know how this turns out. Thanks.
