Another bike, but I figured there may be a common answer. I have a '87 Honda CBR600 and I try to take off the choke or give it a steady throttle, and it'll die. Even if I let it warm up to normal temp, I can only whip the throttle, but I can't hold it. I can also bring the choke about 1/2 way back and it'll still run, but somewhat rough. I hope someone more fuel-knowledgable could help me on what's causing this.
Check your idle screw. Screw it in to raise your idle. At least 1100rpm.
Yeah, tried that. Idle wouldn't change too much no matter how much I turned or which way. I'm stumped.
Cam-chain tensioner too tight?
Perhaps...I'm going to run down all the vacuum lines when I get home today. Hopefully something's loose or disconnected. I'd hate to get into the CCT.

If I recall the earlier CBR's had the CCT in a location that was much more accessible meaning it wouldn't bee too big a deal to change it out. I have a 2002 and it is miserable getting to the CCT on that one. I would recommend going with a manual tensioner if you determine this is the source of your problems.
ASLAM.
Yeah, it's REAL easy to get too. Just one cover and there it is. I already have the bike torn apart, so that won't be a problem if it does end up being that. I hope this worthless manual I have explains how to troubleshoot it. :)
No, it wasn't the CCT. Would it be running lean or rich if it bogs out when there's air introduced into the system? Basically, when I took the choke off tonight, it gave me this "too much air" dying sound. Almost sounded like a gasp. It did the same thing when I barely touched the throttle. The idle won't change no matter how much I turn the adjuster knob. Would a rejet of the carbs or sychro be in order here? I know it's the carb system...I just don't know what to do with it.
