I'm not sure if modern Bullets have them. Mine was '94.
Modern Bullets have a decompressor built into the exhaust cam operated by springs, ramps and bobweights. There's a boss cast into the cylinder head where the second spark plug would be placed, that a few Bullet owners have drilled out and fitted the type of poppet valve decompressor you describe. This is after they've ditched the cam decomp because of the godawful clatter it can make.
My old DR250 has a handlebar mounted lever like your old Bullet. It's timed to be released automatically by the camshaft as I imagine the Panther system does. Or I can hold it in manually to kick the engine over or bump start if it stalls.
