the needle 3rd clip worked like a charm... then we found out the main was rich so we changed it from 350 to 340 and it still was really rich... so we took the airbox lid off..... perrrrfecccct..... absolutely violently fast.... never expected my little toy to be able to lift on power in 4th.... didnt even try 5th or 6th.... my brother bent my spindle and silencer today tho..... he was doing a 2nd gear power wheelie and flipped it..... the front left wheel is bent in on an angle... and the silencer is bent completely sideways....
