DROPPED BIKE OFF TODAY AT GT.THUNDER TO HAVE 440 KIT INSTALLED. WENT WITH CURTIS SPARKS EXAUST, AND 41MM FCR CARB. GUESS WE WILL SEE HOW THEY DO AND IF GT. KNOWS THERE STUFF. SPENT A COUPLE OF HOURS ASKING QUESTIONS. I THINK I WOULD RATHER HAVE THE 11.1 JE THAN THE WEISCO. I'LL LET YOU ALL KNOW HOW IT GOES WHEN I GET IT BACK. I HOPE THEY ARE BETTER THEN EVERYONE SAYS. THIS MEANS IF THEY ARE GREAT AS EVERYON SAYS, IHOPE THEY ARE TERRIFIC. NOTHING WRONG WITH GT. EXAUST, JUST HEARD MORE LATELY HOW CURTIS SPARKS IS. I HOPE IT'S A KILLER QUAD WHEN I GET IT BACK.
