Don't know how good they are, but my friend bought one and is going to put it in sometime in the next month or so (after rebuilding his engine). But there are a lot of good reviews over at honda-tech.

Hmm. I've never considered this mod; Pros? Cons?

EDIT: AND FOR CHRIST'S SAKE WILL IT HELP REDUCE MY DAMNED WHEEL HOP? :(

Pros would be less parasitic power loss. From what I've read, the cons are that if you have stiff mounts (or mount bushings) you will feel more vibration. Also it'd be possible (I've never read of this happening though, but that doesn't mean it hasn't happened), that it could throw off the crank. Of course it'd be more likely to happen with higher hp applications. I know there are a few threads about it over at H-T, I can't seem to find them at the moment though.
