I WAS PULLING WHEELIES THEN ALL THE SUNNDEN THE THROLLE GOT LOOSE FEELING THENI GAS IT AND IT WENT FINE AND THEN I LET OFF AND IT SOUNDED LIKE A HIGH REV IDLE SO I TOOK THE LIL BOX THING APART ABOVE THE THROLLE LEVER AND LOOKED IN THEIR TOOK EVERYTHING OUT AND PUT IT BACK NOW MY OIL ADJUSTMENT IS OFF BUT I KNOW HOW TO FIX IT I ADJUSTED THE CABLE AT THE CARB AND AT THE HANDLE BUT IT DIDN'T HELP SO I'M STUMPED AND IM MAD B/C I REALLY WANTED TO RIDE THIS WEEKEND. I CAN'T BELIEVE THIS BIKE LET ME DOWN LIKE THIS , I GETTING A NEW ONE IN THE NEXT MONTH OR SO BUT I REALLY KINDA SEEING WHAT I WANT WHICH BRAND AND MODEL/

 

So after all that, what is you question? Why it is revving? Does it start fine, Does it idle fine? When does it start revving on its own- After you give it some gas or when just sitting there?
