I disassembled the carbs/cleaned all parts thoroughly. I reassembled with original brass, set the float levels, and installed new (NJ) Orings and bench-synced the carbs. On the bike with engine running each mixture screw functions properly, changing the idle as it is screwed in/out so I don't believe there is any issue with clogged passages, etc. I'll richen the mixture slightly, as suggested.I'll check the tappet clearance/adjust if needed - it was allegedly set properly by the shop tech prior to my purchase...
Went out today and checked the tappet clearance - they were .003"+ so I reset them all to .002" Then I synced the carbs with a gauge set after first calibrating the set so that all gauges read the same when attached to the same cylinder. I had bench-synced the carbs a few weeks ago and was pleased to see that they all cylinders were within a needle's width of each other. I tweaked them so they read exactly the same though I doubt that a needle-width difference matters.I richened the mixture by 1/8 turn on each carb but it was raining so didn't take the bike out to evaluate the change. In the parking garage it accepted a quick throttle movement from idle with less hesitation than previously.One thing that I was NOT happy about - when I started the bike from cold there was visible smoke from the exhaust though it seemed to disappear after it warmed up. Couldn't really tell the color but it smelled oily to me. However, the spark plugs all look good color-wise with no sign of oil or fuel fouling. My wife was behind me on her bike riding to Bristol the other day and she didn't mention seeing any smoke from mine. I hadn't asked her to look for it but I'm sure she would have said something about it had she seen any smoke. In any case, further evaluation is in order.
