1983 Honda CM450A "Hondamatic"

I am the recent owner of a 1983 Honda CM450A, "Hondamatic." I am not familiar with this type of bike, and although all I had to do to get it running well was replace the battery, now I'm having another problem. Anytime I try to shift out of Neutral, and into 1st, it dies. I have no idea why, and for anyone who is familiar with this model knows, this particular model of bike doesn't have a clutch like other bikes. Could anyone tell me why this is happening? I'm totally clueless...

The gerbil that actually provides power to the rear wheel has died or fallen asleep...or the carburetion, ignition or other important system is not working well enough. I found this link: Motorcycle Repair: Honda CM400-A (Hondamatic) transmission problem, honda cm400, balancer shaft .

...and this: Hondamatic Owners Association.

Not familiar with the bike, but does it have a sidestand kill switch that shuts it off if the stand is down and the bike is put into gear? If so, check it for shorts or poor connections.

It starts & runs fine. When it's cold, I have no problems with it whatsoever. Once it has been ridden for a little while, and the transmission gets heated up, if I shift in to neutral, I can't get it back into 1st. Every time I try, it clunks, & then dies. It did it to me yesterday. I let it sit overnight, and then it started up and shifted just fine. Could this be a fluid viscosity issue, or something else? As far as the kickstand sensor goes, there isn't one that I can see...
