I FINALLY GOT TO HAVE SOME RACES ON MY BIKE . AFTER SOME CARS RACING A GUY HEARD THEM AND COME OVER FROM HEARING THE SOUNDS OF THE HOT RODS. WE RACE A TOTALL OF 5 TIMES ALL AROUND THE LOCAL AREA AND IT CAME TO ME PULLING BETTER DOWN LOW WITHOUT HEM GETTING BACK OUT FRONT TILL ABOUT 150 AND HE PULLED ABOUT 1 CAR WHEN WE WENT FROM 60 ROLL. I WAS SUPRISED AS WELL AS HIM. IN ALL IT WAS GOOD FUN. I HACE A FILTER ,JET KIT AND SLIPON
