I have an 03 WR 450 and have just upgraded the starter assembly per http://www.wr450.com/photos/starter_mod/originals/index.htm instructions. Now all I get is the starter spinning, I have checked and it does spin the Idler Gear Assy/Torque Limiter but there is no connection to the engine? I have tried locating the thrust washers in different positions (1 on each side as directed, both on one side, etc.) hoping to get a better bite but with the same result? Anyone have any suggestions?
