Electronic Ignition - Electronic Trigger Plate and Rotor - - XS650
277 Degree Rephase Ignition System by Pamco. Using the same proven design as the Standard PAMCO Hall effect ignition for the XS650, the 277 systems offer a solid state answer for the popular Rephased XS650 engine.When combined with the outstanding single output "Green Monster" coils, these systems will provide the powerful and reliable ignition that you need to get the most out of your Rephased engine.Simple three wire installation: Battery, ground and coil. No external box of tricks.(If needed these parts are available separate or in other kits offered on this site).Note: The 277 Rephase application can be used for either the 277 or the so called 443 timing. The rotor has two slots so that it can be installed to accommodate either cam timing scheme, but you have to be able to determine the correct timing for your particular engine.
