2021-01-04 KZ1300 carb sync

IIt's not easy being a perfectionist. Got all 3 carbs close, but not perfect and could not adjust to 'spot on'.

Decided to to start from scratch per FSM.

Lightly seat each adjustment, then 1.5 turns out.

And, it ran like shit. AND Carb 3 was running at 40 inches Hg, and no adjustment would bring it down.
And idle at 2k even with idle adjust fully out. FSM mentioned that could happen if not in the ‘correct range’ whatever that is
Crap. Should have left it 'good enough'.

Swapped hose/restrictor with spare one from CarbTune. Same result, no change.

Swapped Carbtune port. No change, 40 inches HG. Did I break something? Did the butterfly go 'over center' and is now stuck?

Walk away, come back 30 minutes later. Somehow it still hadn't fixed itself.

Then, magic! While adjusting #2, #3 started dropping. WooHoo!
Apparently, there’s some interplay between 2 and 3, where if one is grossly out of adjustment, the other won’t respond.
I don’t know and wasn’t going to tempt fate by experimenting. 

Ended up with these readings at 4,000 RPM. Since 4k is the 'sweet' spot for riding, decided to balance there
and not worry about idle specs so much...

Now then, if I could only get #1 to raise by 0.5 "Hg, it would be 'purrrfect'. Scew it, I'm done!

Between ColourTune at idle and carb sync, she sounds audibly healthier.

The end.
