The Corbin seat I ordered on 01/31/01 arrived today. For those of you who have Corbin seats, tell me about the fit around the gas tank? The right side of my seat is about 1/3 of an inch shorter than the left side and part of the gusset on the gas tank is visible. I am told by a friend that this is normal fit and finish for Corbin. I would like to know how your fit and finish is around the gas tank before I contact Corbin. Thanks.
