My name is Patrick, I have owned my 73 Honda 500-4 since it was new. I have located and purchased many parts for my 500 from a place in the Netherlands. Yep sounds odd, but they have a lot of parts for the older Hondas. Be advised that the prices listed are in EURO´s. The site however has an exchange rate calculator so you can get an idea of the actual cost. Service is excellent, I ordered a complete set of original exhaust pipes for my 500 a couple years back. They said they would arrive in about 10 days, I had them at my house in three days. Excellent service and easy credit card payment. Some of the parts seem pretty pricey but if you have no other option and want to restore your 500 to original condition, it may be your only option.
