Hi, James, and thanks for the welcome. I'm from Cincinnati, and feel rather lucky as I discovered cruising the web for 550 info a place here called Westwood Honda. They stock all kinds of vintage Japanese bike parts, one of the best in the country, I'm told. Picked up my brake rebuild kits there the other day along with an oil filter. Inquired about a back up ignition key and sure enough, they had one of those. Think I'll be getting to know Terry, who runs the vintage parts side of the business, real well!
