suspension question this time

(1/3) > >>

horror:
I have had another chance to look at the 400.

I noticed that since last time I worked on it (1st time since collecting it off ebay) The rear shocks have collapsed. They have squashed down completely.
I get the impression that they may have been weak ones from another bike added for the purpose of the sale.
Has anyone encountered collapsed rear shocks before?

Also, I have worked on bikes for years but I have never tackled front forks before. I noticed that my forks when compressed they make an air squirting noise.
Also they do not spring back up. I.E when compressed they stay down, and when lifted they stay up. The chrome on the legs is in good shape.
Would the fork seals cause this lack of strength in the forks?

matthewmosse:
sonds like tired springs to me? I get a bit of this on my 500 outfit but that has 6 inch preload spacers apparently and massive milage, new springs are on the wish list. Rear socks wise I've had shocks stick on a low hight, turned out the luggage rack it came with held the tops of the shocks at a funny angle so they wern't parellell top to bottom and were also unable to move at the top because the rack was too close, the damper rods had actually bent from the combined abuse. solution must be to retire them and put on a replacement set.

horror:
Its quite interesting that I was toying with the idea of lowering it anyway. It seems to have lowered itself  :D :D

It's lowered itself but now there is no suspension. And I reckon the forks are an MOT fail as they are.

andy120t:
Keep your eyes on ebay for a replacement set - I think most of the SOHC range will fit as the mounts are the same, athough some are longer than others - so if you find a cheap pair of 750 springs you'll have a higher back end...!

horror:
Yea I'll do that, I have never seen rear shocks collapse like this. I suppose the bike could be fitted with 125 shocks or something, and maybe they
were too weak.
I would like low rear shocks, Have You seen this one?

It's lowered at the back with some posh rear shocks by the looks of it. I haven't got the dosh for this but it would be nice to get some like that
