86 mm  is 3.3858   stock bore so that would  mean 3.3828  has .003  thou clearance wiseco says .004

Whats the minimum clearance you could safely get away with with Wiseco?

wiseco builds the right clearance in for 86  stock bore..since there skirts are tapered it would matter where it was checked at
