I am hoping that the list can help me with a couple of clutch questions:
   
  1.  I've noticed there are two types of Polaris P-85 clutched - narrrow 
roller and wide roller.  The wide roller seems to be from larger engine 
(600-700) machines.  Knowing that the bore will need to be machined to fit a 
494/493 regardless,  what would be the preferred clutch for our application - 
narrow or wide roller?
   
  2.  Am I correct that the correct bore/depth to fit a 494/493 is 30mm / 1.75?
   
  Thanks, Cory
