After reading all that, I'd love to see you ride!

Sounds like your timing is 180* off. You should recheck your timing marks again and recheck your valve clearance. It doesn;t sound like a fuel problem. Hope this helps.. If not give us more info about who built it..ect..

start with the basics...

1) spark
2) compression
3) fuel

if you've got all 3 it should run...

Ok here we go 400ex Motor 101, check the cam timing first the cam lobs should be down on TDC TOP DEAD CENTER the cam gear has two slashes on it they should line up with the top of the head u should be able to se them both the slant towards the front of the motor, if this is correct your timing is good, you should have a service manual in front of you because with out it you could have never known the torque specks for the studs that hold the jug on or the head bolts this manual should tell you everything your need to know. My engine turned over 1 time and started so its not rocket science.

Wow, you must have a big oil tank 2 liters is a ton of oil.
