1. I made sure there's free play in the cable.
2. Today I took the tank off and removed the cable, making absolutely sure that the cable is not interfering with the mechanism. It still seems to stop against something and cannot be adjusted lower.
3. I checked the fast idle. Cable free play is okay and where the little lever engages with the mechanism I can see daylight when the handlebar lever is closed. Only when the handle bar lever is activated and only when all the free play is taken up does it engage. So the fast idle mechanism is not interfering.
I have read in many places that if I touch the individual butterfly adjustment screws I should not expect life to ever be the same again - don't do it. But what if a previous owner has adjusted them?
The mechanism bottoms out against something before the idle control screw touches the stopper. And at this bottom position it idles too fast. My conclusion is one of the butterflies bottoms out. Is this possible?
I thought I would seek advice before I remove the throttle bodies, turn the thing upside down and check out my theory. The thing is, what if this is the case? If my suspicion is confirmed I need to venture into that nether-world of adjusting the individual butterfly settings. Anybody have suggestions?
