hi, i'm very new at vintage bikes. I just picked up a CB360T last weekend and have trouble with the choke and idling.

1. Choke has to be on to have the bike idle or if i close the choke, it will die.

2. it has to idle at 1,800rpm ~ 2,000rpm or it will shut off.

3. it makes a lot of ticking sound (i'm guessing valves need adjusted)

otherwise, it runs really good, no problems at all.

are all my 3 conditions normal or are there any solutions to each of these?

thank you all..

All you stated could be due to munged-up carbs .... Clean them..... Then let us know what's going on.... at 1800 RPM you are getting fuel through the main jet.... The idle jets are probably plugged up with varnished gas..... Steve

thank you for quick response Steve. So just to confirm, Idle jets are in the carbs correct?
Also in theory, once the idle jets has been cleaned, it should idle at less rpm without the motor dying, correct?

I will start tearing apart the bike this weekend and start with cleaning the carbs. Thank you again, and here is a quick picture of what she looks like now. :)

Just to back up what Steve said, when cleaning the carbs, only do one at a time to avoid any confusion. Make sure all passages and jets are clean. There are passageways that go through the carb body. Spray cleaner in them and it should come out somewhere else on the carb. Watch your eyes! By the idle jet I assume you mean pilot jet right Steve? Sounds like clogged pilot jets to me?

GB...Yes pilot jets, and I was just about to mention doing one carb at a time.... From his post, I'd suggest a shop manual before he does anything.... Maybe Bill can fix him up with a bike specific CD...... Steve

Termigni....Yes and yes to your questions..... Steve

My bike seems to have the same symptoms. I just cleaned out the carbs and they seem to be nice and clean they really didn't have much of any varnish to begin with. Any ideas?

Thanks for the speedy reply. ok i'll take em off again. I'll post pics of them also. Since this is my first experience with motor mechanics not sure if anything is unusual about the jets. The main jet's hole goes all the way through but it looks like the pilot jet has a metal plug in the hole not sure. Will post after work.
