  From around 1969/1970, Zundapp has completed all engine blocks with a 91mm connecting rod.
  Before this an 85mm connecting rod was used, which can also be recognized by the low-pin pistons.
  If you have a motor block with a low pin piston, this cylinder will not fit.
  It is possible to assemble a new regular crankshaft with a 91mm connecting rod, and it is possible to mount this cylinder again.
