Boocat, Graeme is correct, the link he posted was one of the best more recent "recurring" threads about the chain tension.
Points to consider are that the Triumph and the Haynes manuals do use some generic measurements. ie; 40mm for the Speed Triple and the Tiger? The Tiger has at least twice the travel of the Speed Triple, so chain tension can't be the same on a fully extended (de-weighted) swing arm.
As I mentioned in the other thread, your weight, your passenger's weight and any intended luggage carriage should be loaded on and then check the tension. Make sure you find the tightest point in the chain when you do this. Once you have that right, you can then remove all the kit, and measure on the side/centre stand to give you an unloaded measurement to use for future adustments. As I also mentioned, I find it best at 60mm, but that's me at 85 kilos and Gabi at 50 kilos.
