So a sort of update now, I stll get the arm pumps, now really fast! After like 10-20 times under the same 'section' I get arm pumps... I had my lever in a 'my standard' position, but it's pretty fast isn't it? Can a magura get seized (A forum spelling nazi is welcome to correct that word) up when it's left unused for like 2-3 months, on a factory oil bled?
