I know it's illegial but we ride in a cool area with no other traffic. Jacob my son on my Kawasaki 650sx, 44sbn, intake, westcoast exhaust and pipe, pjs water pipe, skat impeller. GPS'ed at 43.8 yesterday standing up. He has been riding for about 20 gallons and can ride 45 minutes without coming in. He usually gets on his knees in a fast corner, turns sharp then right back to stand-up, WFO until he is ready to turn again. I'm so shocked how fast he picked this up.
