Thatsnjust it....i HAVE worked on the area that should be suspect and everything else i could think of. Thats why i posted, cuz believe me i didn't want to ! It's gotta be something leaning it out but for god's sake, i just got done finding a problem that had it running rich no matter how low i took the jetting, and it ran great. now it's set as rich as it ever been and it's lean ! I couldn't recreate this scenario in my worse nightmare ! The problem must be an overall (both cyl.) lean condition since both plugs look lean and the hesitation AFAIK is a symptom of running lean. But with no apparent air leaks i'm not sure what it would be. i suppose i'll try hooking up the evap and see if it then starts running rich again. Maybe somehow that fix WASN'T.

heres a question.....on the bikes with no Ca. EVAP on them, does the T fitting on the float vent tube nhave a hose on it, and if so does it just hang down as a drain or if not where does it attach to?
