Topic: Rear Cushion rebuild

[Nicolai]

I can't find any info on how to rebuild the rear cushions on my CB500. Does anyone have any info on this?

[B.O.X.N.I.F.E.]

Here's what you'll need:

High density foam - call an upholstry shop for this
batting
spray adhesive
contact cement
possibly saran wrap

You can get the other stuff all at Hobby Lobby. Use the electric knife to cut away the bad foam. Lay down contact cement, then lay down the roughly shaped foam. Finish shaping it with the knife. You'll then lay down the spray adhesive, and a light covering of the batting. This will keep irregularities from showing through the cover. My seat was in nice shape, and I wanted to seal out moisture, so I layed down spray adhesive and then a sheet of saran wrap to keep moisture out.

The knife is cheap, and you can return it when you're done. You will need it though.

Haha, I should have caught that, he's from europe.

Just like those aussies and their damn 'bonnets'.

 I think he means the rear shock absorbers.

Most of the OEM (factory) shocks cant be rebuilt. The shocks that can be rebuilt (Betor, Koni,etc) usually have a hex where the shaft goes into the shock or a pin spanner (wrench) type of arrangement that allows the shocks to be disassembled.

Ha ha...yes I meant the rear shock absorbers. I wrote cushions because that was how it was written in the manual. Shock absorbers would actually be the direct translation from danish.

Anyway...I have to take a closer look at them to see if they can be disassembled.

I always wondered what it was that would wear out in the stock shocks. 

If it's just the oil and the seals are intact...couldn't one simply bore a hole to drain the oil from, tap the hole for a drain plug, and bore a flat surface to mate a crush washer to, then drain and refill with denatured alcohol and move the piston a few times then drain again, and then after blowing out with compressed air (or letting it sit in a warm dry place for a week), refill with the correct grade of oil and install a plug with a crush washer like stock front forks have?

I know it's quite a bit of work, but would this do the trick? Yes I know there are suitable replacements available.
