Poor fit and alignment of seat and tail piece

[Toddk]

Anyone have a solution, mine lookslike crap. I see alot of them, does anyone make another bracket to close up the gap?

Add 2-3 large O.D. 6mm flat washers to the front two retaining bolts of the tail piece and (if needed) grind a little off the trailing edge of the under seat trim.

My theory is that the seat foam shrinks after more than 30 years.

i recently had a new seat cover fitted with a thin layer of new foam added. No more gap!

Part of the problem can also be with the seat pan. It likely gets bent upward when the seat grab rail is used to put the bike on the center stand.

I improved the fit a great deal on one by removing the seat, placing it upside down on a firm surface and applying a reasonable amount of force on the bottom of the pan.

To simplify, I put it on the floor and stepped on it. Definitely improved the fit!

Pictures please.

Take the cover and foam off the seat pan and you'll find it's easy to bend it back straight.

Trawl through the fiches for the bodywork, frame, instruments, etc. and replace all the rubber bits and bumpers and all the body hardware you can with fresh OEM.

Rubber shrinks with age, spacers, washers, and other hardware go missing and get replaced, and over time, nothing on the bike fits quite right. A surprising portion of these bits are still available.

For stuff that's NLA, figure out a reasonable replacement. I've used rubber washers and bits of rubber sheeting to shim up , and I've carved rubber corks from the hardware store into replacements for various bumpers.

Hello,
My bike had that problem. In my case (GS1000S) it was a bent seat pan. Bending the metal back made all the difference, no shims or new parts were needed.
This was a suggestion from another forum member, not in a million years would've I thought of that. In my head a seat pan is not something that "bends". But there you have it.
Remove the seat from the hinges, put a couple of small pieces of 2x4 underneath in the middle portion and bend the crap out of it.
