When taking abs pump off I suppose to swap proportion valve for non abs (single piston) one. I highly doubt that I'll find one so I'm wondering what happen if I'll leave twin piston one?
Another idea I've had, since most of braking force goes on front brakes can I just bypass proportion valve for front brakes and just fit t piece.
Or could I put small adjustable bias valve for rears?
Last one how are brake circuit split on Pulsar is it one for front one rear or is diagonally?
