Finally got the bike running last week, (77 cb750F). One problem I'm seeing that I'm not sure how to fix - at rest, with no pressure on the throttle, there is no tension on either the push or the pull cable. Ok so far. BUT... the idle will not come down. If I put reverse pressure on the throttle, forcing it shut, the idle DOES come down. When I look at the linkage, I see that the cable linkage does rotate a fraction of an inch, and disengages the accelerator pump. Without the reverse pressure on the throttle, the choke linkage re-engages the accelerator pump and the idle increases. (the choke linkage operates on its own spring). Why, if the cables are both slack, does the throttle not return all the way? I can see that the cable linkage (the round plated that the cables attach to) does not return all the way to its resting point, but stays about an eigth of an inch off of it.
Update - I checked the accelerator pump clearance, it was a bit tight so I adjusted it to spec (.2mm), but the situation hasn't changed. What is causing the change in rpms? The throttle slides don't move, what else is taking place????? Very confused. Another question would be - how far out can you turn the idle control screw before it disengages the tab that it pushes against to adjust the idle? I need a comparable bike to look at, methinks.
