Brake issues

[Dangerous]

Hi can anyone advise.
350lc, when i bought the bike some time ago it had a KR1s  front master cylinder which is 5/8, with brembo calipers,

worked a treat but ive always wanted the original LC master cylinder , which i recently purchased.
Now fitted, but for some reason im having difficulty getting it right, ive bleed them through but the brake lever has hardly any travel, meaning ive to really pull the lever in hard for the brake light to be activated .
Im not sure what the brembos are off, so if you zoom in on my avatar you will see them.
Any suggestions welcome and thanks in advace.

Have go at backing the adjuster screw on the lever out so you get more travel on the lever

Small return hole in the master blocked

This can mean the pressure is not released so the pistons don't back off a little
