Porscheguy912: do you have a 78 or a 74 CB550?
What about your needle position?
Can you accelerate smoothly all the way to redline with no bogging?
Any flat spots or bogging?
Did you oil your pods?
What is the code on the side of your carbs? PD series?
I'm working on my 77 CB550 with PD46C carbs.
Pods, MAC 4-1, 114 mains, and the bike is bogging out over 7k RPM at WOT. I think it is too rich, but plug chops show no changes on my plugs no matter what I do. The plugs always look perfect! I'm also running Dyna ignition and coils.
Thanks
Hay man, I have he same year and setup.
I rebuilt the carbs and used 110 mains.
I have 4-1 open pipe and k&n pods.
The bike screams! And i even get in the neighborhood of 50mpg too!
I bought my jets from some canadian company.
They are big on ebay, if i remember the name i will repost.
good luck!
