Topic: 1979 cb650 Choke Usage

[Borth42]

Hey guys,
I feel that my bike takes a little longer to warm up than what I am reading in these forums.
Carbs are clean, but takes about 7 miles or 15-20 minutes of stop and go riding in order for me to push the choke all the way in.

Anything to worry about?

They are from the "lean burn" era like the 750F2 and 550K3 and they all take a long time to warm up and idle properly
