Are you guys still happy with the JR. ? I'm sitting on the fence getting ready to by one but was waiting on feedback from you guys. I had a Quadzilla zxt but took it off because it had to much timing rattle. Hows the rattle with the smarty jr? Are you getting more MPG with normal driving?? I figured that its Feb. now and all that bought one at xmas time would have results by now. . Would appreciate the feedback thanks, Brian
