CB1100 Idle speed instability problem
Hello guys, I am back. After waiting 2 weeks for the IACV to arrive from Honda I waited another 2 weeks for the valve cover gasket to arrive (I plan to inspect the valves while I have the bike apart to replace the IACV). I spent almost 3 hours on the bike on Saturday and I don't even have the air filter housing removed yet! I spent about 45 minutes just removing the fuel tank! That fuel line connector sucks! I used pliers (against the recommendation of Honda), brute force, and finally WD-40 and finally it came apart. The black, rubber, outer piece makes no sense to me. It is completely flexible and I can't see where it is doing anything except taking up space. I should have pre-read the instructions in the manual before starting because it would have saved me time. I am flipping back and forth between about a half dozen sections in the FSM just to take pieces off the bike like the fuel tank, the rear fender (fender "A" and fender "B"), and the air filter housing. I plugged the new IACV in before disassembling anything and it appears to be functioning properly - it cycles each time I turn the key on. I probably won't have time to get back to the bike until next Saturday, but hopefully I will at least get the old IACV removed by then. I apologize, but I am not fully taking pictures and documenting every step of the way. I am working slowly and carefully, (yes, I am really slow, but I don't do this kind of work very often) and I am trying to not make this task any longer than necessary. Hopefully I'll remember how everything goes back together when I reach that point (could be two weeks before I get that far, as I am limited to only having a few hours available on Saturdays for working on it). Wish me luck!
