Rear cylinder richer
Dialing in the new top ends and it seems to be tuned pretty good except that when pulling plugs to check, the rear cylinder is slightly darker, I understand that it is normal.

That would only fix his idle circuit-
We don't know at what load or RPM he took the plug check at, and I am betting this just confused you and most everyone else.
Everyone that wants to know what their AFR is must put in a wideband unit.
Or, you are just guessing.........and more guessing.

People pay more for the bolted on chrome BS.
The AFR will save you hours and days of screwing around.
To weld a bung in is a 5 min job. If you dont weld, just take the pipe to any muffler shop that has a wire feed.
Use a 1/2 inch hole saw to cut the hole front pipe backside.
A piece of cake job all in all.

All the pieces to put it together looks like about $300 and then chasing the perfect numbers tweaking it for a week. I wonder about that sensor blocking exhaust flow. Just thinking out loud.

My bike runs very well.
i am not going to give you a list of all I have done to it, but it is a long one.
This year I am trying 50 deg valve seats.
Raised ports.
With a carb and high CR numbers, its is a piece of mind.
You don't need purrfect numbers, just ballpark for your situation.
Purrrfect is for F.I,
Most everyone knows HD engines do not like lean numbers. They run hotter an hell.
