'83 GS850 GL - New Springs Confusion

[Phred]

I had the same problem with my 81 L, took it all apart and discovered that the new springs were for the G model. Did the same thing with longer spacers, a huge difference in the ride. I also have my seat to redo, and am ordering a new cover from PITREPLICA. What kind of foam are you using?

I have some 1.5 ince memory foam from an older project ,.
I first reshaped the existing seat and used kneeling pads from a big box home products retailer...then a layer of 1 inch ..and next the memory foam and a new cover ..
Results will be reported ,but it has to be better than the 31 year old L seat ...
