Despite living with it for eight years, the stock seat on my 1100GS has never been very comfortable for more than two or three hours at a time. I aquired a Corbin which has a totally different feel but digs into my thighs at the front and is no better than the stocker after 200 miles - plus it weighs a ton and the pillion seat doesn't fit with it. Based upon the outstanding Seat Concepts seat I installed on my DR350, I have purchased a Seat Concepts kit for the 1100GS. Rather than tearing apart the perfectly good stock seat, I am trying to use a seat pan that came from a salvaged (underwater) bike. The seat pan was apparently damaged by a Bavarian upholstery gnome's over-zealous use of a trimming knife during assembly and at some subsequent point, the pan split. Here is the other side with the seat foam removed I have used a heat gun to soften the plastic and get it more-or-less back into shape but now need to repair the actual split. Plastic welding seems like the obvious way to go but I do not have any experience and am not sure what material the pan is made from. Do not really want to spend $50 on a hot air welding kit if there's an easier way - or if it is unlikely to work anyway. Can anyone offer any advice please?
