I know this isn't a direct ST1100 question, but I'm working on my brother in law's '91 Nighthawk, which I believe has the similar Keihin CV carbs as the ST1100.
We've opened up the carbs twice now, cleaned the jets and they are clean. Fresh lines, squeaky clean tank, and added an inline filter, stock airbox, fresh air filter - stock exhaust is slightly opened by a PO. We fire up the bike, and it idles fine, but give it any gas and it dies. Even after warming it up, you can only rev the throttle with the choke on. I believe this is telling me we have a lean condition. All the jets are stock #35, #112.
There are pilot screws we haven't touched - could that be a culprit based on our symptoms?
