just quickly about the plugs.
being an NGK r really doesnt say much about the plug. Its detailed specifications are buried, encoded in the part number, for example bcr6es and bcr7es. the numbers relate to the heat range of the plug
a 0.7mm gap shouldnt cause any problems although for mild tuning is a bit narrow. From memory until you're running aproximately a bar then a 0.8/9 mm gap did people fine with the heat range 7 plugs.
