  1.      Introduction
  In order to reduce the machine weight, the             To improve the durability of the short circuit wire,
  aluminum guard used in the past has been replaced      a new switch with a terminal socket is to be
  by the new magnesium guard.                            introduced, as well as a new "crankcase, fan side"
  To simplify servicing procedures, the poly V-belt      with an additional fixture for routing the short circuit
  pulley and shaft, the handlebar with corresponding     wire.
  fasteners and the water attachment have been           With the introduction of the new carburetor and
  changed.                                               switch a new tank housing will also be used.

3.1.1   Supply of spare parts
The previous versions of the "starter cover with
rewind starter" 4224 190 0300 (TS 700) and
4224 190 0301 (TS 800) are no longer available as
spare parts. The new versions of the "starter cover
with rewind starter" 4224 190 0304 (TS 700) and
4224 190 0305 (TS 800) can also be installed on
older machines.
The previous versions of the starter cover
4224 190 0400 (TS 700) and 4224 190 0404
(TS 800) are no longer available as spare parts. The
new versions of the starter cover 4224 190 0410
(TS 700) and 4224 190 0411 (TS 800) can also be
installed on older machines.
In the future, the starter covers with groove will be
supplied as spare parts together with the longer
hose.
