My post was about to know if a combination with Genmar products was doable, if I would want to go a bit further. One guy said a
3/4" Genmar spacer AND Heli combo would work but after rereading his post he didn't said specificaly he didn't change the hydraulic hoses.

I've been there before . On one Busa i ground the brake line banjo fitting stop on the master a little so i could re-clock the stock line. It was just OK and still too tight long term but did the job for the one week needed. For the permanent fix, got a longer braided line.
In the end i ditched it all and went to a bar kit. I came out OK since i bought the risers and Heli's used.
