help needed with '95 Blade shock mod.

[Drewski]

I've bought a used Fireblade shock to fit on my CB1.Can anyone tell me if;
a) I have the right shock?
b)Can I use the shock with the standard gas bottle pipe?
Thanx.

Fireblade? I can't remember what model number that is? Is that a CBR900?

[Drewski]

Yep, its the CBR900RR. The old forum was littered with posts about fitting this shock. "It just bolts on" they all said. But I can't see how, it looks like the pipe to the gas bottle is too short. To replace it with a longer one would require taking it to a specialist and loads of dough!

93-95 blade or 900rrs shocks are a drop in deal.

Zip ties keep it in place. Larger image at my photo gallery.

Here's a few pics that I have. I'm going to do a write up on this, but haven't had the time.

Below is a '95 CBR900RR shock next to a stock one. There is a place for the rezzie as shown in the following pics. I attached it with a large hose clamp and it's solid as a rock and still adjustable from the side. Take a look. And yes, it's a bolt on deal. Simple install.

As far as shock settings. I weigh 180lbs and had the preload all the way to the softest setting. Rebound was the lowest and compression was at 1/4. This was good for city driving. Highway only riding you might want to make it a bit stiffer. On the stock shock (12,000 miles on it)  I had the preload set to the max and it still bottomed out on large dips in the road.

Excellent, thanks very much and good luck with the forum.

 OK peeps 

 I have used an RRS unit, installed a 10mm longer CrV shaft, changed over to a non-leak-by 46mm GP piston (reshimmed it); and settled on a 190Nm (19.3 Kg/f) spring with 10mm loading on it.

 Stock blade springs are 15.2 Kg/f or thereabouts (depending on the factory having a good day) - I gradually went up with whatever I had lying about... to a 15.6, then just over a 16; then to a Hawk spring, a Hornet 600 spring, before finding the 170mm long Ohlins 19.3 for virtually nothing - and hey presto! None of that over preloading to compensate for bad spring rate (had the hornet spring on 23mm in the end!!!). 10mm compression from free length is usually where I aim for anyways... just a shame I had a whole bunch of rules to adhere to; so I had made myself not use any new stock I have - part of the challenge was to find stuff on ebay! And it were lucky really that the piston was still here unused since leaving a GSXr shock last year - waste not want not!

 Shock at 30 GBP, spring @ 12 GBP, some oil and N2 + my time... (which is free to me!)

 Anyhows, to you guys this means a short cut I guess. The spring is now right, and if u wanna know: I weigh 155lbs..

So I finally got a blade shock on ebay. Should I put a different spring on it, if so where can I get one?

[mechdziner714]

Is there an Ohlins Part# for the spring you got?

A further thing to point out is that the Fireblade shocks are 10mm (bolt centre to bolt centre) shorter!!(and this at spring setting 1...gets shorter the more you stiffen the spring)...has anyone found that difference in shock length gives any probs with grounding out or tyre wear as it brings seat lock quite close to the edge of the tyre and also to the  edges of the undertray...

I just picked up a '93 Fireblade shock for 40 dollars US!

Any tips on the install?
I've read this will raise the back end up a little bit? Any ideas on how much?
