Works great, but really tough on the Sportster because the master cylinder and brake pedal are on opposite sides of the bike, so you feel like an "ape" doing it by yourself, or get smart and have a "helper" to press the pedal.
Thats the left hand on the spanner and right boot on the brake pedal whilst laying over the seat method for that one
perhaps in a year or 2 i wont be able to get the stretch right for the sportser but then ive trained all members of the family to assist in break bleeding and they all hate sitting in the car pumping the brake pedal to dads instructions
