Okay...We've been up and down the "Power Now" road. But, I thought I'd just pass along that I think the thing works. I just put mine in Friday, and went for a ride on Saturday. Of course, it's not like going from WR to YZ timing...but it is a nice boost when you crack the throttle open at lower rpms. Is it $69 worth? The jury is still out on that one, since at this very moment, $69 is a lot to me. But just for the record, beyond all the trash talk, on the bike, this thing works pretty well for a simple bolt on product. I would recommend it.
