Read the h2lt instructions.  The thread pitch changes the preload turns. The h2lt has a very different adjustment process. The limited lifters do not eliminate noise, they are best for high spring pressure builds to help with hot starts.

About .050" off the bottom. Without the thread pitch no way of knowing the turns

Not 4 turns from the top. Bottomed without oil in them and 1 turn up, .042 off the bottom.

S&S uses 32 threads per inch.

Jerry, he has SE pushrods, 24tpi
If we were really splitting hairs, the 24tpi will obtain the same extension at 3/4 of a turn vs the S&S instructions for the h2lt of 1 turn with their pushrods. In my experience not critical. At 1 turn we  are talking about a
.009" difference.

Adjusting off the bottom is not conventional but it is required with the h2lt lifters

By changing the cam you changed the engines requirements. It needs to be retuned.

do you think i should also change the gas injectors for bigger? or it is not necessary

When you tune the bike they can check the injector duty cycle and that would determine if a larger injector was necessary.

thank you for your answer but with us the performance measurement is too expensive about $ 400 and to complete it 2 times is not very advantageous so I would like to do it for the first time

Most good tuners have injectors in stock and change them in the process of the tune or can determine early on and ask the owner to change them before investing much time.

Once they heat up the motor up on the dyno within a pass or 2 of Wide Open Throttle they can tell you what the injector is doing as far as duty cycle.   It is very simple to do and will give you definitive data on whether larger injectors are necessary.   If they say they have to do a full tune to find that out find another tuner.

I'll try to ask like this, did someone change the cam 585 on the cvo 110 and had to change the injectors?

Not needed with just a cam swap.

Totally agree. Your stock injectors are fine.
