One thing to remember about the 400 is that it is a Suzuki, no matter what color the plastic. It will not have the same engine mounts as a 250F or 450F, so you will have to modify the engine cradle again if you switch it later. Truth be told, the 250F is also a Suzuki, considering they designed it when they were working with Kawasaki. Be patient, you'll find a 450F. Like 3Razors suggested, the KLX450F is a five speed, has lights, and could easily be retrofitted with a kick starter using factory parts. Kawasaki might even have a kit for it. Once again, be patient. The 450F just came out recently, so there aren't as many of them around just yet. Please don't put a Suzuki engine in it. Keep it all Kawasaki.
