So I got the bike running again today. CB500. Ran once when I got and hasn't been driven since 1991.
Here is the list of things done:
Carbs rebuilt by a forum member
Cleaned petcock
Sealed tank
Replaced with Dyna s ignition
Replaced with Dyna coils
New Mac 4-1 exhaust
It sounds a bit loud. It quieted down a bit once I tightened the exhaust down a bit more.
Giving gas bogs it down as shown in video.
I have 627B carbs. Harisuluv moved needle clip to 5th from top from 4th from top and used 110 main jets.

The first time it was ran since 1991
