Just purchased a nice example '78 Trail 90 with some wiring issues. I was able to find an original service manual pdf online but saw there's a guy on eBay selling service and EPC info for 60+. Service manual is helpful but the views in the ad look even better. Does anyone know how he gets this info and if theres a way I can access it? I've gotten the SIS day pass before for other Hondas but doesn't seem like theres an equivalent for small engines. Thanks
