Throttle Control Cable Slack

I would need some advice on how to remove the cable slack that occurred when I changed my throttle control.
The throttle grip on my LM3 was sticking and the engine on/off switch was bypassed. The original part had both throttle control and switch on the same mold and that part is discontinued so I installed a Tommaselli throttle control.

Now I have about 1cm (1/2") of cable slack.
The throttle knurl and nut adjustments are at maximum length and I still have too much slack.

I had a couple of ideas .... but what would you do in my place?
Should I change cables completely?
Should I install spacers between the cable support brackets and chamber to increase the length going to the carburetor rods?
Or can the existing cable be cut to length and some sort of pivot installed (on the carburetor rod side)?

Thanks
 
Cutting the cables shorter is possible but you need new barrels to put on the ends. Once upon a time you could buy them from companies like Barnett. I don't know if you still can.
I don't like the spacer idea because of the concern for what happens if they slip, move, or fall.

Whats the advantage of changing to flat top versus what I have now?

The bell cranks are notorious for increasing the pull. Not only that but the larger barell on the Tomaselli decreases the travel but increases the force needed to twist the throttle. Using flat tops with elbows can give you a throttle as light as an FI bike.

I purchased some parts at MG cycle and they do have these so called barrels to put on the ends.
They call them "emergency throttle cable repair fitting"

Spacers would be ..... a patch-up! :sick:
