    i asked about this a while back.. i chose not to go with one because of the damage they do... they're meant for race cars who's motors get rebuilt before every race

    They're balanced, but they're not dampened. Huge difference, and I'm honestly surprised people(not directed at you) still don't know the difference or get those two confused.

    Balanced is self explanitory. Dampened, IIRC, has to do with obsorbing vibration that can cause parts to stretch, weaken, crack, and eventually explode. Most commonly are the oil pump failures.

    I'm sure someone can eleborate a little more...

    I run the CTR pulley on my setup with no problems, it shaves a considerable amount of weight of the crank. Honestly the best way to go is The Old One - Energy Dynamics This will emliminate harmonics that are bad and eliminate the unecessary belts that you dont want. If not go with the CTR pulley.

    Honda installs them on the B16b's striaght from the factory, I wouldnt think they would do that if it was gonna throw the crankshaft outta whack. Either way its a Honda manufactured OEM part..

    wrong.. Honda made it for the N1 race cars.. hence the name CTR N1 crank pulley .. the pulley on a factory CTR is the same a b16a

    Seems to be your best bet, but is it really necessary to take weight off your crank mass, worth the effort?

    As long as you're not making much power or doggin it all the time, and possibly change the oil pump, should be fine. You can try to bolt up a damper to it though :)

    Also, I should add that the smaller the stroke, the less torsional vibration there is.

    As far as people blowing their motors; there was about 4 I believe on H-T when I last checked(this was like 2-3 years ago). Plenty of other people with blown motors with aftermarket ones.
