It doesn't mater if he does race, rally or NASA, if he does not know, he does not know  ;)

  it might be an idea to publish the clearance ,

 in simple figures, and advise the best way to achieve it,
IE;  measure the piston,and add X thou for clearance ??

I wish it was that easy Mr Webley, it all depends on the grade of alloy used to make the piston, different alloy expands at different temperatures. Honda original pistons were made from a very high grade cast and the clearance can be kept at a minimum. A less grade will expand more and would require more clearance  ;)
