Topic: 1977 CB550F Muffler Question

[Michael Wilson]

I just bought a 77 CB550F and it does not have a muffler. I don't want to pay a ton of money for a nice new muffler as this is my first bike and I am still learning to ride. Can anyone suggest a good muffler I can pick up for cheap and install without re-jetting? The bike also came without air filters. I have purchased and will be installing Uni Pod Filters, so I supposed that should be taken into consideration. Thanks for the help.

If you are putting different filters AND a different muffler.. I think you are going to need to work on your carbs to get ideal performance.

Which means, of course, you can choose any muffler you like

buy OEM stuff if you dont want to tinker but pay more for it

Thanks. I am planning on working on the carbs before I get the muffler. Do you suggest that I put on the filters and muffler first?

you can clean them out real good and make them look good. do a bench sync. but your not going to be able to jet them without a little tinkering with the bike running. I'm sure there is a 550 GURU here that can give you a recommendation of what size jets to put in, but its all gunna come down to testing it.

Thanks for the tips. A little update. I cleaned the carbs, bench synced them (trying to find some vacuum gauges to do it proper), adjusted the air screws and idle screw. Bike is up and running all-be-it on the rich side. Next up: Checking the plugs and wires to make sure everything is firing. After that, I will experiment with jets. Thanks for the help. More tinkering lies ahead.
