Fit the ati pulley and be golden, As to why you would ever even think to fit a solid pulley is beyond me, Honda fitted a damper for a reason so dont try to out smart them, I think I have posted this on here before
Harmonic Balancer rather than Billet Pulley
Harmonic waves can travel thru the drive train and thru the crank. If there is nothing at the end of the crank to absorb the wave, it will travel back in the opposite direction to meet the next wave. This causes the unfavorable harmonic vibration. The first thing to take the abuse is the oil pump gear and you know what happens when that breaks. ALSO, pulling weight off of the crank that close to the center line will add ZERO horsepower or rpm capability. Don't fool yourself on this. Think of how big and thick the counter weights are on a crankshaft. The harmonic balancer is just another externally added counterweight that happens to absorb negative wave energy. Honda engineers were not stupid or naive. Don't try to out think them in this case, use a harmonic balancer.
