The idea when you add weight to the handlebar ends is to add LOTS of it.

The handlebar is actually responding to the engine's vibrations and will vibrate in harmony (resonate) at certain engine RPM. You can change the resonant frequency of the handlebars so that the bars do not respond to the engine vibration at say cruising speeds (shorter stiffer bars will tend to cause the high amplitude vibration to shift to higher speeds, longer or weighted bars will tend to cause high amplitude vibration to shift to lower speeds). Some manufacturers include weighted bar-ends as part of the design.

Weighted bar-ends are added mass that will lower the resonant frequency of the bar so it vibrates less strongly but does not eliminate all vibration. In many cases, that's enough. You simply change the resonance to a frequency that the bike rarely generates or to a RPM that has less effect on the nerves in your hand. Shifting the resonant frequency is intended to reduce the strength (amplitude) of the vibration at your normal cruising RPM.

I went to a dive shop and paid $3.00 for a 3 lb. lead belt weight (wheel balance weights and lead shot mixed with epoxy would work too), cut it up witha hacksaw, hammered it into shape and shoved/wedged it in the handlebar. Covered it with the stock end plugs. The weight's got to be in there tight to work, closer to the free-end works best. The lead piece in each of my handle bars is about 5 in. X 1/2 in. semi-round.

Those aftermarket bar-ends and Barsnake-things they sell in bike shops aren't going to help as much.
