NOTICE for 2006 Standard FZ110 Engines

Changes to regulator & gasket sets for YS110 engines:  FZ110 engines built in 2006 were fitted with a different regulator.  

The original regulator diaphragm (#73 above) for the FZ110 engine has been replaced in 2006 models with a 2 part gasket-diaphragm (#A & B above).  The new gasket is not included in the standard FZ110 gasket set (part #YSE2020) for YS engines built before 2006. 

To replace gaskets in standard YS FZ110 engines built in 2006, you will need both the FZ110 gasket set (part #YSE2020) plus the new regulator gasket (part # YSE0745).
