tps evaluating for ii issues

Hi team, new update: Rode the bike about 10 miles on city streets last night. The low idle condition is now rearing its ugly head more often, and stalling is now becoming more common. The bike initially started normally, and had the normal cold / high idle condition as a normally running CB1100 should have. As soon as the engine warmed up and the cold / high idle returned to a normal, 1,050 RPM idle (approximately 2 miles of riding) the low idle condition began, (this was at the third or fourth stoplight). At the third stoplight after the low idle condition began (700 RPM, slow return to 1.050 RPM) the engine stalled. I restarted it, and it stalled again. I restarted it again, and gently revved the engine (up to 3,000 RPM) several times to keep it running, and then let it return to idle, which was 700 RPM. The RPM slowly returned to 1,050 by itself, and then almost as if someone flipped a switch, it returned to 700 RPM by itself. At this time the light changed and I rode off. I reached my destination about ½ miles later without stopping and turned the engine off. I restarted it approximately a half hour later, rode it another 5 miles before turning it off again, and it ran fine. I restarted it approximately 1 ½ hours later and rode home, deliberately riding a route with more stops, and it ran fine all the way home.

I am planning to perform the EVAP hose disconnect test this weekend. My thoughts are to disconnect the two outer tubes as shown by MAX, and connecting two blocked-off tubes to the throttle body nipples in their place and taking the bike for a ride. What do you think of this Max?
