The early relays by Siemans were not up to the task, especially the starter relay. Under the seat there are a series of five relays which represent just about every circuit in the harness ( starter, lights, neutral switch ,coputer and fueldelivery/ignition.
Upgrading the relays is cheap, easy and sure to enhance reliablity somewhere down the road. Most have upgraded to the Bosch unit but there have even been reported failures of those ( very few). The GEI units are in service with a few riders and we're all watching for the long term results.
