wow what a deal!!!in my case, I have a 2002 bike, the ECU was showing a code for the Left Knock Sensor.
I did an online search on Craigslist and found a bike only 30 miles from me, it was a 2004 that hit a brick wall so hard the forks were folded back under the engine.
I felt very comfortable buying a bunch of parts off that bike,
would you believe $75 for all of it?
