Did you pull out the forward chain guide/pad? I had and created a loop in the chain underneath the lower drive sprocket on the engine.
I had to remove the forward chainguide/pad. Hold the forward cam chain taut, and rotate the crankshaft clockwise. This will pull the loop out. Holding the chain taut again, re-insert the foward guide/pad.
The forward and after chainguide/pads (or what ever you call them)have very little clearance for the chain to ride through. It is physically impossible for the chain to fall to the bottom of your engine with the guidesin place.
I am off to bed right now. I'll check in in the morning. If you are still having trouble, e-mail your address or phone number. We'll get you squared away.

I cannot wait for Moab. This will be my highlight in oh, say the last 5 years at least. It would be more like 7 years, since I quit racing mx in '93.

I had the same problem. I just kept moving and shoving and pushing the cams (very gingerly) until they eventually plopped in. I set up the intake cam first and zip tied the chain to it. Then I worked with the exhaust cam until it finally plopped in. It was not easy. Sorry I don't have more for you.
