Hi, I live in Missouri and have recently purchased a 2009 KX250F. It is in immaculate condition and even the motor is flawless. Only has 15 hours on a complete rebuild by the kawasaki dealer. However, my intention was to find a rolling chassis but I got a good deal on the whole bike. I want to sell the engine and it even has a nice titanium Pro Circuit exhaust. Anyway, back to the topic at hand. I found a company that will modify the frame, subframe, airbox, and radiators to accept a 2005-2007 kx250 engine but they want $1,500 to do it. I'm trying to do this on a budget and I know someone out there has done this swap before and knows what all goes into it. If i could get some tips or instructions on what all I need to do it would be greatly appreciated. Thanks in advance. Jesse Witt.
