® The CB500/550 page



Here is where I celebrate the Honda CB 500/550, a machine I really admire. This bike and I have a lot of history. I owned one at almost the beginning of my career as a mechanic (selling it with over 92,000 miles on) and now near the end of it I am again enjoying one. In between I have seen, serviced, restored and rebuilt countless others (and am currently rebuilding an engine for a friend's 550). I will try to put some to-me important facts together for those who appreciate this model as much as I do. Here are some of the things I plan to talk about:


  • Should you really put on Dunlop Gold Seal tires?
  • Why was the bike changed to a 550?
  • Is the 500 really inferior to the 550?
  • Is the charging system inadequate?
  • What about silicone brake fluid?
  • Does the cylinder head really need to be milled?
  • Is there a crisis concerning the carburetors?
  • What about cylinder compression?
  • How is brake squeal best eliminated?
  • What about ethanol?
  • How critical is the rocker shafts issue?
  • What about replacement 500 clutch pushrods?
  • Is there an ideal battery for this bike?
  • Why should you install an ammeter and how?
  • What makes me like this bike so much?
  • What about sohc4.net?
