Hey guys, one of the guys that rides with us at my track completely ruined his motor last weekend. He ran it without any oil and completely melted everything. You name it, its broken! Now since he is going to pay me to mount the new engine (500 bucks) I figured it would be worth the time to post this and see what ideas you all have. It is a 2007 YZ 450. he needs a new engine, or a used one, and even from other year models if 07 not available. The two dealers I called said they could only order the parts. I find that hard to believe. Does anyone have any experience or know of how and where I can get a new/used engine? I have been looking on ebay too.
