My 2004 LTZ400 was stolen 14 years ago and was recovered a week ago. (I was 22 and now I'm 36) crazy right? I received the quad with the motor out. It only came with the bottom end, no cylinder or head or piston. Im assuming they pulled this out because it was seized up? This bike was missing for so long and to finally get it back I feel like I just owe it to myself to get it running again. Plus I have a family now and would like to get them all into riding. So my questions are, how would you approach this? The bottom end of the motor (crank case) is completely out of the frame. Do I go for upgrades or just slap all stock parts back on? Cams? Drz base gasket? Should I buy a manual? I was hoping I could get an idea where to start with this project. The bike does still have a Dyna FS and a yfz 39mm fcr keihin carburator. Oh yeah, no exhaust either. Can you guys help me out?
