thanks Dennis. i did replace all the vacuum lines. it is acting like the advance is not working properly. i've worked with vacuum advance on cars but never on my bike. back to the books!

thanks GM. my other 12 doesn't have any hesitation but the gray one is pretty pronounced. it ran this way before the rebuild. when it gets past the bog it seems like it sort of surges or at least comes on harder than it should so, as Dennis suggested, i'm thinking vacuum advance may be a possibility. is there a quick and dirty test for VA like plugging a line? i'll copy that trick to my desktop. thanks again. btw i tried adjusting the air/fuel mixture screws and got no response from 2,4 and (as best i can recall)3 but did get a drop from no. 1. another concern.

I swapped ICU's and it didn't make a bit of difference so the good news- it's not the ICU. The bad news- it's not the ICU. Still haven't done the sync/drop yet so it can only get better after that. Last week I tried to do a simple idle drop by ear. I was a little chagrined because I didn't get any noticeable response to turning in the pilot screws until the last one which happened to be no. 1 I believe. Ya I know not exactly the textbook approach but I didn't do anything dumb like torque down on the pilot screws. Anyway, just the lame attempt at the idle drop made a noticeable difference in the off idle bog problem I'm experiencing. I wonder if the timing is off. I just got my first Goldwing about 6 months ago so I've got a lot to learn. Timing inspection plug? Doh! Right now I've got all the pilot screws roughly 3 turns out. Cali calls for 3 and a half but heck I was afraid they'd fall out at that setting. I'll keep at it thanks y'all for the help.
