Since changing them out, I have a similar problem.  With the bike on the
center stand, the engine running, ant the transmission engaged, the chain
begins to jump up and down, eventually threatening to jump the rear
sprocket.  It also looks like it's getting enough tension to nearly stall
the motor at idle.


Nothing wrong with the chain, or anything else. You are just hitting some
harmonics that as the engine varies it's speed a little at idle (between
power pulses, it changes the pull on the chain, then the chain starts
bouncing around because the wheel inertia is changing. To avoid that, just
raise the idle (hold the throttle open) a little.
