Sticky throttle
« on: February 29, 2012, 07:44:30 PM »
So, decided to keep the bike. It looks fun.

Took apart the carbs, cleaned the hell out of em. New plugs, starts way better.

Wehn I hooked up the throttle cables, I noticed that when the bottom one (return cable?) is hooked up, the throttle wont back down. When I take it off, it seems to work fine.

Thoughts?

It's binding somewhere.  Check the cable back to the throttle.

Make sure there is a little slack in the cables or they will bind.

I had the same problem with mine 77 CB550K... I realized after a bit that the push cable was from a F model. I have ordered the correct K model cable and still need to install it...

Might have the same problem... (no tank installed, no bend, just the cable looks a tiny bit shorter on the F model compared to K model)... On the other hand, the pull cable does not fit at all if it is from a F model...

It worked fine until took off and put back on the carbs

Still sounds like your cables are too tight and binding, they need a little slack to opperate correctly, check your adjustments ;)

You mean the nut system that connects to the carb?

On my 650 the adjustment is on the top cable where it attaches to the carb rack, there are 2 nuts on the outer cable so you can adjust the length, the bottom cable just has a flange and a nut that locks it up tight.
