hi formz,and a warm welcome from spain.first things first.put your bikes details and your location into your signiture line.1980 CX500
Rebuilt the carbs, although they were immaculate when I pulled them apart so they didn't need much cleaning. The bike starts right up but it just will not stay running without the choke pulled. It responds to throttle input just fine and if I give it a little bit of gas it will stay running without the choke.
Some other things that may help: one cylinder seems to be running a lot hotter than the other judging by exhaust temp. I'm also getting slight backfires/sputters out of the exhaust. I know the gas is clean and I have a fuel filter on it.
Any ideas? I tried adjusting the idle with the screw but it doesn't seem to do anything. I'm stumped!
if you are happy your carbs are lean....sweet
because you need choke,it sounds as though you have dirty carbs.but,
...your last line says something else.idle screw is the only big black knob,yes?located between and under the carbs
winding it in or out does nothing,is that what you are saying?
