Hey everyone! My name is Angel and I work at Motorcycle Factory Inc., in Woodbridge, VA. I'm going through my parts inventory and see that I have 2 Kawasaki Adjustable ECU's that we got on closeout in 2010. The Kawasaki part number is 21175-0136 and says that it fits 2008-2010 KFX450's. They parts retailed for $627, I would like to sell them for $75.00. If you would like one please contact me and I will be happy to get you set up with one.
