STmark1300
Ron
I bought a barely used ST1300 seat and had it spencerized. It was quite uncomfortable and I didn't know were to even ask about changing it. So I bought another seat and it was OK. Then I lost about 60 lbs. The seat seemed very uncomfortable and my butt seemed bonny. So I decided to try the Spencer again. To my surprise... it was great! So my observation is that weight makes a BIG difference with these seats.
