Troubleshooting -- rich carb? UPDATED 8/16/10 5:30p

UPDATE 7/28/10:

Today I drained the tank, then removed the carb. I looked in al the passages and made sure they were clean, blowing them out and examining. I checked the needle in the diaphragm and found it was a single-position circlip. After reinstalling the carb and partially blocking the air filter (HiFiltro), still ran like crap. Very boggy on accelleration with a stumble past 1/2 the rpm range.

Removed carb again and modified circlip needle slightly. I shortened the "top" and tapered it like it was, then added the stock washer and one additional washer underneath the circlip and above the plastic spacer. The 2nd washer is just a touch thinner than the stock one, for a total of maybe 1.75 "effective notches" lower on the needle. I re-installed and removed the blockage from the air filter. Went for a ride, and voila! Almost like new!

The "pickup" still isn't perfect, but I got 78 MPH on the freeway, so that beats the barely 60 I got before the circlip mod.
I plan to re-tune the idle circuit to regain the pickup, and will post my final here (though each bike will vary, so don't take it as gospel.)

I also added some Berrymans, but I doubt it's having an effect as I found no blockages.

Will post back later this week or early next. Thanks for the help!
