tps evaluating for ii issues

Hello to all you great guys working on this low idle problem! First, thank ALL of you for all of your support. I will clean the IACV electrical connection ASAP (this week) per the instructions emailed to me from Doc.

Been working O.T., and had to run to three different stores this evening to find a new battery for my P.C., and just got that replaced. It's after 10:00 PM and I just logged on. The VFR800 work can wait until I clean the CB1100 IACV connection, but I really need to finish the VFR fork rebuild and steering head bearings replacement before I tackle the CB1100 IACV replacement. The VFR is apart in the garage, and I am out of room to work.

What do you guys make of the constant sound (IACV cycling?) I heard when my bike was running seriously bad last Saturday, when it was stalling? Do you think maybe this indicates the valve was sticking? Does hearing the sound possibly mean that the sensors and ECM are operating correctly by sending a signal to the IACV?

What do you think about the condition I described where the low idle condition seems to be temporarily cured now when I turn the ignition key off and then back on again (I leave it off for about 5 seconds before turning it on). Does this disprove the sticking IACV theory?

The Factory Service Manual (FSM) has a procedure for checking the operation of the IACV (I read it several months ago, and don't remember the exactly details right now). If the valve is operating correctly (per the FSM check), is there a good way to determine if the valve is sticking? Can I insert it into the throttle body and make an accurate judgment?

Thanks again guys, I really appreciate all of you.

Hi Dave i copied and pasted this from post 146;

None of us have a clear idea of the exact part that is the cause of the fault, however there are some things that have not been done and that is cleaning all connectors to the sensors;
a map sensor 3 pole connector ( left hand side behind plastic cover ).
b iacv 4 pole connector ( right hand side under plastic cover )
c evap purge valve 2 pole connector( right hand side under throttle body )
d air temp sensor small 2 pole connector up high ( left hand side under cb1100 side cover ).

The most telling clue i found that there is still a noise coming from the iacv AFTER the engine stalled but ignition is still on, that means to me that the valve is still commanded to get to 1050 but is mechanically unable to do so.
Provided that i interpret that correctly.

If you switch the ignition off and on again you have also re-cycled the iacv every time the fuel pump is running on switch-on.

I have made a new thread about the iacv that may help you;

see what you think

So i would try as many of the abcd tips as you can, and yes, you have to lift the tank first and remove the plastic covers

Cheers
