2strokespirit Posted December 6, 2007 Report Share Posted December 6, 2007 WISECO!!! You must check your bore size. Or....may be French pistons..... Renault pistons?? ... Just Joking! Wiseco the way to go!! Quote Link to comment Share on other sites More sharing options...
. Posted December 7, 2007 Report Share Posted December 7, 2007 if ring spins it is because bore/piston clearance is to great. Either from bad bore job (bore should be to the .ooo (thousandths), or from wear Go with wiseco, micrometer bore, and then buy pistons for application, then bore after pistons are micrometered Quote Link to comment Share on other sites More sharing options...
