My buddy is helping me get into a 2006 KX450f. He is working on the motor as we speak looks like part of the skirt from the piston broke off scarred the cylinder. He has a cylinder on order and going to split the cases to inspect everything. The question I have is on that particular year is there anything that you know off the top of your head that I need to be aware of. Like recall type problems or errors that I need to watch for on this bike. Thanks for all the heads up.
