Honda 400ex No start
When you reassembled the engine, did you make sure the timing chain tensioner was wound up and held tight when you installed it? If you don't wind the timing chain tensioner and keep it tight while installing it, it will cause the chain to be too loose, the tensioner will not do it's job.
I recommend taking the chain tensioner off, winding it tight and reinstalling it.

Yes I made a little T out of sheet metal for holding it back. I turned the engine over a couple of times then rechecked the marks before putting the rocker cover back on. I didn't look at the valve seats but I did set the valve clearance after I put the cover on. I even pulled the flywheel when I changed the stator to check that the flywheel key didn't sheer off.

I have this same problem with my '06 400 EX. I get it started and running while choked then when I shut the choke off it will start to die. I changed the plug. I am in the military and am getting deployed so I don't have any time to look at it. I am thinking the carb is dirty and the gas in the tank needs drained and new gas put in. It was running great one month then I didn't run it for a few weeks and then it started doing this crap. O well prob something simple like gas. Just need the time to drain the tank and put new gas in.
