I'm new to the WR and I've searched the forums but I can't seem to find anywhere on how to make a "PowerNOW" for an '04? It looks like the older models have a collar in between the air box boot and the back of the carb where the PowerNOW goes? Am I right? What do you do on the '04's? I've noticed I could buy from Scary Fast but I can't seem to part with the money right now. Any help would be great, Thanks.
