FCR tuning issue

[memper]

So my plugs are still not equal. Though I have read that our engines tend to run richer on the rear cylinder. Is this true?
Should I enrichen or unlean the carb on the front cylinder or just leave it alone?
Front plug is still off white with a patch of brown.
Rear is a tad rich.

You want the cylinder to run correctly, not both carbs to be adjusted the same. 

It's not uncommon to have completely different jetting for horizontal and vertical cylinders, especially on idle jets.

Thanks for confirming.

The bike actually runs pretty well aside from a tiny flat spot at around 30 mph (I have no tach). And not liking starting when at 200 degrees.
Just the whiteness of the horizontal plug has me concerned a bit.

Is 30 mph passed the pilot jetting and into the needles at that point?

So I'm trying to sync again (first time I just put it back to where it was -fully screwed in).

I have noticed that while the lock screws are loose, the adjuster nuts do nothing. Carb is vertical.
If the lock screws are removed, the adj nut makes the slide go up and down. When the set screw is put back in, the slide gap closes up again. Adj nut is not allowed to move while tightening the screw.

*Edit: If the idle screw is backed out all the way or removed as Pat Burns suggests you cant see any slide gap. So I did the opposite and screwed the idle all the way in. Doing this allowed me to see the adj nut at work and I was able to set the slide height.
