I have photos in my computer home about the cable installation on the TMR’s.  I’m in Spain now close to Benidorm, so no garage nor riding. Sunshine, sea and beers are OK too.
I know that I had to add an extra nut I made a cut in by a saw blade for the wire to use the nut as adjuster or lock nut. Nut is open so not tight too hard, lock with Loctite. One cable is a little bit long, front adjuster at the switch/ throttle is in outest position. Maybe I can adjust at the carbs a little bit more.
Edit: Here photos when I installed them

Jetting sorted out since then
Pilots 30
Fuel screws 1 1/2 turns out (stable idle and less need of choke)
Needles 2:6
Mains 135 (more open pipes 137.5)

I have got the carbs (Mikuni TMR32) to work better last week! No more minor stumble and occasional sneezing carbs at low lifts.
Increased pilot jet 1 size. 
(I cheaped out ordering EBC jets. They worked fine though. There is a risk that they are different than Mikuni (despite same size stamp) that I have heard flow tests their jets)

Pilots 32.5
Fuel screws 1 1/2  (Or just a little less)
Needles 2:6
Mains 135 (137.5 with Hindle 4-2-1 exhaust)

Fuel: Shell V-Power
Engine runs smoother with Denso X24ES-U than NGK D8EA.

Update:
Pilots 32.5 way too lean with Hindle 4-2-1. Might have been the problem earlier too

Bike stumbled at take offs/ really slow speed, very irritating
Carbs got bigger pilots yesterday, 35 same brand EBC
Engine idles much better and need choke only the first 30 secs  now. Twist throttle slowly from idle(1200-1400) to 3000-3500 rpm much smoother now.

Pilots 35
Fuel screws 1 1/2
Needles 2:6
Mains 140 with Hindle 4-2-1 exhaust)

** Update after some testing **
Lifted the needles 1 step, now 3:6. Needles have effect really early on these carbs.
Pilots back to 32.5
Fuel screws need to be 2 turn out.
Main jets still 140
