550 YSS rear shocks

[DomP]

Roo has got me thinking about new rear shocks since showing us all his shiny new TEC shocks!  Before I take him up on the offer of his YSS shocks I want to see if I can get the YSS Ecoline shocks to fit my bike, I like the look of them as much as anything.  They don't offer much choice of shocks with fork lower mounts so I'd have to use some intended for another model, they do cb750 shocks at 335mm long but wonder if they may be sprung a bit stiff for my 10 ½st, other than that they do a set for cb400s, will these work?

[DomP]

OK, slightly simpler question,  cb400 or cb750 shocks on a cb550, has anyone tried it?

I had to put 750 shocks on my 550 mongrel as with the 550 ones, the inner mudguard was hitting the tyre if that answers your question, the 400 shocks are the same length as 500/550🤔🤔

[DomP]

Thanks Julie, at least I know I should be fine if I went for 750 shocks then, except I've dropped the front end about an inch and have clip ons

Received my new Hagon shocks today, the lower mounts are the wrong bolt hole size, do they intend me to mess around with bushes or are they wrong?  They were made to my requirements and sprung for my weight so I presumed they'd come with the correct clearance hole and thread size to use the standard bolts especially as ive replaced them with nice stainless ones from Middletons

Well that is a bit rubbish isn’t it, I would definitely expect the shocks to come with the correct bolt hole and thread size. If not then at least supplied with new bolt and bush kit.
We have to put up with so much of this, incorrect size, not quite right, have to spent hours getting supposed correct stuff to fit cr**.
Hope you get a good conclusion from them and a shock with the correct fitting.

It is really considering the cost of the stainless adjustable shocks,  hopefully they resolve it in the new year.   I did give them every detail possible, the chap I spoke to called Tony was very helpful so I think it will all be good, im sure they dont expect me to get bushes to insert through the oe honda bushes.

Hagon have had my shocks back to alter them, got them back in the post yesterday so excitedly went to fit them only to find the lower fork mount is still too wide for the bushings by around 2.5mm.  Surely this isnt right that ill need to shim 'bespoke shocks?

[Bryanj]

You shouldnt, but i will say that hagon do list different shocks for 400,500 and 750 whilst Girling, whose business Hagon took over, listed the same shock with different springs

The lower mount must be able to move slightly, so don’t lock them in place if you do use washers.

[DomP]

OK Ken, that makes it more awkward trying to find washers with a close enough tolerance.  I even gave them the bushing width when I returned them because the first set were very much too wide and with 8mm thread not 10mm.

[Oddjob]

If the gap is that small that finding a washer could be a problem then it's not vital a washer is fitted.

[DomP]

Should it not clamp up to the inner metal collar of the bushing as then any flex is taken by the rubber?  Have you seen the gap in my photo Ken?

Is the bush on the swing arm central and fully home?
How does the top fitting alignment look, is the damper unit nice and perpendicular in the frame axis if you get my drift?
