The seat may be two things; too high and too much tension. I adjusted my B17 none after the initial fitting. But I also soaked it with Obenauf's leather oil. It is the only leather conditioner I have owned that smells like new leather. The underside of the seat MUST be treated too. Take the seat off and make a "bowl" of aluminum foil which will hold some liquid and the seat. Pour a generous amount of the oil into the upside down seat, spread it, and leave it to soak. Ten minutes in, you can turn it over and soak the top as well. Another ten minutes and you can let it drip a bit onto the pan and wait overnight. Rub down the outside with a soft cloth, install and ride a bit. If it is still too stiff let off some tension from the bolt under the front. Only do about 90 degrees at a time. I always soak a B17 with the provided proofhide first. Then go to the Obenauf's. The proofhide can be used entirely but you will need a tin of it. That tiny packet provided with the saddle isn't enough. Good luck and Be Well, Bluesfrog.
