tps evaluating for ii issues

Dave,
"AS" forget about this...it should be written ..."as" far as to PCSV....

>>>>>>>>>>>>>>>>>>>>>>>>>>
1* test condition:: on center stand, engine hot/normal operating temp and NORMAL RPM (1050)..if for any reason is not within specs, wait until it stabilizes within..
2* disconnect THICK/YELLOW vacuum hose end **that goes from PCSV to Th. body/intake manifold = this will create vacuum leak or as if PCSV were stuck in open position (normally closed) and register RPM change....it may very, so watch it for a while..
** careful, not to break nipple to PCSV
Unplugging the electrical connection will not be the same thing as removing the hoses (Popgun is perfectly correct)

>>>>>>>>>>>>>>>>
YELLOW SKINNY HOSES DISCONNECTION...might be more difficult to achieve , since there is less access to inner throttles ??? have a look..

Max is recommending that I disconnect the two EVAP ( skinny vacuum hoses/yellow & blue, linking each th. body, Honda calls'em MAP vacuum hoses) system hoses (hoses identified with yellow marks in previous post), and I assume that this is the same thing as the PCSV?(..generally, all seems to go to intake manifold) . 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 = YOU SHOULD SEE RPM CHANGE...watch for a while what is happening with RPM...may go up, down...

Let us know, please... before next step as per Max/SportsterDoc/Popgun
