How does she idle? No more "idle hang" ?

At the risk of speaking too soon I think the idle hang is history.  There's a little delay in rpm drop but I believe the cables are the culprit. I plan on lubing and adjusting again shortly.

I am regulalry reminding myself that this bike is going to perform like a 40 year old bike. My oldest rideable bike up to this point is my 2000 SV and my Thruxton was a modern bike dressed in retro garb.  I WANT this bike to feel old in all the right ways but it will take some saddle time to feel really comfortable with its personality.

Just goes to show how the original engineers of these carbs knew what they were doing.  The designers of after market stuff just figure that if the threads correct and there are holes, it's good.  Even the length of the jet maters.  The original jet is submerged deeper into the fuel in the bowl.

Could be the aftermarket parts were made by machinists/mechanics rather than actually engineered for working function in a specific model carb. 

Hey, I resemble that remark
