Speed restrictor removal- what is done?
(may be illegal in some states!)

Remove the kick start cover by taking out the screws on the outside edge. The people model has one in the center, also


  make sure you get them all
  ensure that the starter pinion (bendix gear) is seated fully in position, it sometimes comes out of it's hole when you remove the kick cover 
  use an impact wrench to remove the nut on the front pully (crankshaft)  right hand threads  Hold the crank from turning with your hand
   remove the outer pully half 
  remove the belt from the crank, and hold the inner pully half in tight to the engine while pulling the boss out
  hold the pully tight in place and don't move. or the parts will fall out of it. No big deal, just takes longer
  insert the new boss, the new one has no shoulder on it. it MUST slide right in, easy.
  and bottom out smoothly, just like the original
   slip the belt back on
  put the outer pully half back on, being carefull to get the splines aligned properly. You must be able to spin the nut on by hand, all the way so that the clutch halves are bottomed out together. Wiggle the pully with your fingers while spinning the nut on to be sure it is on all the way, and correct.
  Tighten the nut back up with the impact, put the kick cover back on. You are done!
