This is beginning to drive me nuts. I've posted here before about my low idle and have gotten good suggestions and fixed a bad TBS job. Now the fun begins.
I have a 24 mile commute on back roads at 50 - 60 mph until I reach the Interstate and ride 75 for 7 miles to the plant I work at. For the past several rides the bike runs great until I get off the Interstate. Then, the idle drops and stumbles and I must keep revs up to keep the engine running. In the evening, it'll start right up and run just fine until I get almost home and then the same stumbling idle until I pull into the garage, To date I have added new plugs, air filter and searched for a bad vacuum hose. I have 'shocked' the fuel system by removing gas from the tank until 1 bar is showing on the gauge and adding 8 ounces of Seafoam, running the engine until warm (to get the concentrated seafoam mix into the injectors). Filled the tank up wih non-ethanol gas and let it sit over night. When started, no smoke or soot came out as I was expecting.
Occasionally the yellow engine light will come during this stumbling. No error code is displayed, just the yellow light.
I'm afraid I will have to seek out the local dealer for relief. But it was that same dealer that screwed up the TBS to begin with. Have any of you guys ever experienced or heard of these symptoms? I can't think off anything else to try.
