Not to go into great detail here but I may trade off my 2008 yz450f for a 2010 kx450f. The kx has new rebuild and new plastics with decal kit on it..... My yz is in good shape but could use some new decals and has never been rebuilt, but to be fair it's only trail ridden... So doesn't need much attention. His kx has a full yoshi pipe and header (think that's what he called it) and has billet parts and so on... Long story short is it worth me trading, it will cost me my bike and cash... Nothing wrong with my bike I just like the way his looks... But out of all fairness for the amount of extra cash I am giving him I could re do the looks of my bike too.... In the end... Carbed yz or FI kx?
