the bike wont be BTZ or HKZ (CDI) once you have fitted them, but if yours is HKZ, you will need some coils as well, one off a GT380/550/750 Suzuki (single outlet) and one off a GS1000 (double outlet), be sure that the coils you buy are genuine ND and coloured beige, aftermarket stuff is not always that good.
