FI light came on after washing my bike
I wanted to start a thread to maybe help some others out if they run into the same problem as I did. I have a 2006 ZX6R with 5800 miles. I washed my bike the other week just like I usually do with a hose and soapy water. Ive never had a problem with this before and figured it was ok to ride in the rain so a little water wouldnt hurt it. Big mistake on my part. After I washed it, I took it for a quick spin around the block to get any extra water off it and noticed it was running a little strange, almost hesitant to rev but I didnt think much of it as I was only doing low speeds and I didnt have my helmet on so I didnt take much notice to the different sounds as I thought it was just because I didnt have my helmet on. I parked the bike and called it a night. The next morning I get ready to go to work and jump on the bike and after a few minutes of riding, the FI light comes on and the bike literally just starts running like complete crap. I have a 45 minute ride to work and was only about half way. I take it real easy the rest of the way and make it to work. I figure maybe some water got somewhere it wasn't supposed to and hope that sitting in the sun all day while I'm at work will dry it out. After work, I get back on the bike and the light is still on and its still running poorly. Also, the normal sounds that come from under the tank are replaced by a terrible screaching and grinding sound like the throttle bodies are stuck and struggling to open. When I get home, I whip out the manual and check the codes from the FI light. I get a 32 and a 62, both of which have to do with the subthrottle activator and sensor. I did a little searching online and on several forums and found a few others who have experienced this after washing their bike but none really explained what the problem ended up being or how they fixed it. So I set to work taking the bike apart and following the service manual checking anything I could that didnt require the special kawasaki tools. Everything was checking out fine but there were several areas I couldn't test without the special tools. I called a few shops around town and found one that was very knowledgeable and steered me towards the TPS. He had seen this same thing happen before. He told me to replace the throttle body assembly. The throttle bodies contain several sensors, including the subthrottle sensor and the throttle positioning sensor. Its easier to replace the throttle body assembly than it is to replace these sensors. So, I get online and order a set of throttle bodies off ebay. Today, they arrived and I bolted them right up. I cross my fingers and turn the key...no fi light! No more terrible sound. Everything seems ok. I havent completely finished putting the bike back together because I am getting the tank painted to match my new fairings so I have to wait for that before I can fire it back up but it seems to be fixed. So lesson learned, be careful when washing your bike with a hose. And if you get a 32 or 62, the throttle body assembly is probably the prime suspect to replace. Let me know if any of you have had an experience like this.
