currently the best place to look for parts unfortunatly seems to be Ebay. Cosmo went out and they did it in stages, their stock was a mess and stuff got auctioned off in random lots. and some other companies that did buy up large lots (like Domi racer) went Kaput as well and that stuff got auctioned off as far as I know :doah:
I would suggest snatching up the parts breakdown books if you see them for the hurricane and the dynamo, as alot of times certain parts are just listed with the part numbers not what they are for.... the sellers that just bought out auction lots don't know what half the stuff they bought is.
another important thing on these is the tail light bulb needs to be in place for the bike to run, it sort of completes the circut so if its bad or not there no spark. so along with cleaning the points etc., clean the wiring grounds/connections and the bulb and socket.
I have a Hurricane, I have been collecting NOS parts for it but I have not touched it in years. Its currently stashed away up at my mothers home along with a couple bins full of parts under a workbench for a rainy day
