Suggestion AS TO PCSV only
Make a long test short::
1* test condition:: engine hot/normal operating temp and NORMAL RPM (1050)
2* disconnect vacuum hose **that goes from PCSV to Th. body/intake manifold - NOT to canister = this will create vacuum leak or as if PCSV were stuck in open position (normally closed) and register RPM change. Please
3* Do not bother any other tests with EVAP/PCSV for now.
** careful, not to break nipple to PCSV

Hi peterbaron. Please excuse my ignorance. What is "AS"? PCSV = Purge Control Solenoid Valve, correct? Max is recommending that I disconnect the two EVAP system hoses (hoses identified with yellow marks in previous post), and I assume that this is the same thing as the PCSV? This seems like a pretty simple test that I can do. If my bike is running fine (1,050 RPM, warm idle) and I pull off these hoses what should I expect? I believe that Max is saying that if I pull these hoses off when experiencing a low idle condition and the idle speed increases, then this could point to a defective or sticking IACV, is this correct? Doc has suggested that I unplug the connection to the EVAP purge control solenoid valve (PCSV). Will doing this test achieve the same results as unplugging the two EVAP system hoses? This sounds like a pretty simple test that I can do also. Thank all of you guys for your continual support.
