I picked up a 1998 yz400f recently. I was looking for a project bike to fix up and flip. Well resell and hopefuly not actually flip but ya never know. This will be my 3rd bike rebuild. Last winter I did a frame up on my beloved 1995 xr250r which I bought new. I then tackled a crf230 that had melted down a piston. Here is what it looked like when I picked it up. Engine was totaly froze up but I thought I would take a gamble on it.
