it looked to me like a combination of too small a booster, with a master which is volume/split for a different system. seemed like either an 11" booster or the correct master could overcome the fault of the other.
I will be doing some pressure testing on different 1.125" and 1" masters this spring.
Their manual brake kit should work ok, because they use a master which is smaller than the pedal ratio calls for. I cant see it working as well on a 70+ though. Guess I'll find out.
