• Was on hotrods site looking for a 500 crank and saw they still have them for 88-92 250,s but not the 87.Just curious what the difference is between the 2?

• Functionally nothing. The 87 crank is heavier than the later models with a little differnt balance ratio I would expect.

• So then would the counter balancer be a tad different on the 87,s as well?

• The balance shaft in a 87  is a little different from 88 to 92,It take smaller hole oil seal which the 88to 92 has a big hole seal.The bearing are the same,just different oil seals.
  The ome parts look up say same shaft all year 87 to 92,

  This... They will interchange with the correct oil seal, same for zilla cranks I believe.
