Choke will not stay engaged
« on: May 14, 2009, 09:07:49 am »
On my '78 cb550, once I pull up the choke and take my hand off, it falls open again.

Any one else with this problem, or is this normal?

At the base of the choke knob is a friction adjust.

.... if thats the entrance to canada, sign me up!




ooh... sorry got hypnotized by your avatar....

NO idea on why your choke drops closed.
.... sorry.

IS the 550 a cable actuated choke, or like the 750, is there a lever on the side of the carbs?

If it is a cable, look for a "tightening" nut to increase the tension on the cable.
I know 650 carb setups have a hidden nut for the choke cable to increase the tension on the line to keep it from falling on it's own.

The round section that holds it onto the bracket is knurled so that you can adjust the tension by hand.  Try tightening it.  Of course, that doesn't always work, especially if you have lubed the cable.  So, either get used to holding it up until the bike is warm enough that you can ride it, or go buy a new OEM cable from Honda and don't lube it.

Perhaps it is possible to clean lube off of it with some kind of solvent (kerosene?  brake cleaner?) without destroying it.

I can twist mine slightly clock wise and it will stay without using the friction adjust. It will slowly right itself and start falling. s'weird man.

Thanks guys, I have never noticed a knob, but will give it a look when I get home

The knob is often covered in a rubber boot to protect it.

Actually it's more of a knurled ring than a knob, but it sounds funnier that way :D

Mine has a rubber sleeve over it so that the knurls don't knurl your fingers.
