Rear shock , another way ?

Post  gus on Wed 28 Mar 2018, 4:21 pm

I wanted to replace my Gen 1 shock with an "as new " shock from a Gen 2 . The gen 2 shock is a much stronger item but is too long (about 20mm) to fit a gen 1 .
Other times I've  played around with different shocks I have got them to fit but had to adjust the dog bones , a right pain .
The mounting on the bottom of a Bandit shock is a U (POINTING down ) AND an eye on the top . 
I'm thinking this should work .
Place bike on centre stand .
Place something under rear tyre so its a snug fit .
Remove original shock .
Fit bottom of shock to link age . 
Make a bracket to fit frame that is longer .Attaching to original bracket .
Mark new eye position  . Drill and fit new shock ..
Bolt up and remove spacer from under rear tyre ,
Should work 
Shouldn't it ?

Sounds good to me, but going by my past efforts with suspensions you might want to check with some others   Rolling Eyes

Six of one, half a dozen of the other.

I just usually make new dogbones, via the same method you described, to get the ride height I want.
I've got spare stainless plate lying around, so dogbones it is for me.
I made some two weeks ago, and it only took about hour and a half to make them, from first measure, to final clean up with grider. I use 1mm cutting discs to get the basic shape,and the 1mm's cut like they're cutting butter. Very quickly, then touch up with a grinding disc, then a flapper disc to remove sharp feathers. Always match drill the holes so the equal.

What ever method you use, just don't extend anything by welding two bits together. Make them out of one piece only.

The dog bone method doesn't work on all shocks . If the shock is longer it catches on the bottom knuckle . The Gen 2 will have to stand up straighter  .
I think I will have time tomorrow to test it out . 
Ive been working on some ones  kz400 Kawasaki they swapped for a bag of weed . Don't know who got the better deal . Its got no reg \rect 
so I stripped all the wiring and switches and wired up "total loss ignition " . It hasn't run for 5 year and I shat myself when it  started and ran at about 6000 revs . I think the cam chain is about 2 kls long , talk about rattle .

Yeah your right in regards to interference.
It can also interfere with the swing arm.
I'm actually having this issue at the moment, fitting a gsxr 1000 shock to my second gen1. The thing I'm struggling with is, I've already got one on my current gen1, but it's not fitting my second gen1.
I want to try a different method, for experimentation only, and that's try a longer clevis lever, if I can find one compatible.
This will also charge the ratio of swing arm travel, but finding a compatible lever will be fun. Still don't understand why the gix won't fit, as per the other gen1. Exact same shock, and same bike, but that's another story. ...
The 07-08 gix 1000 is 312mm, and if I recall, the gen2 shock is 319-320mm long.

What about a different spring on your gen 1 shock , ...................or I had a collar fitted between my spring  and adjuster plate on a rear shock once to stiffen it up ( about  10 mm from memory ? )..............my spring wasn't particularly stuffed,just a bit soft . Similar thing to putting spacers in front shocks I suppose .
Your other idea also sounds ok .

Hey Gus, I've just been looking at a Suzuki parts list, and I've noticed that the part number for the cushion lever, is different from the gen1 compared to the gen2.
I also see the gen2 is the same part number as the early water cooled.
Now, in saying that, may be your gen2 lever will fit in the gen1, to make it compatible with the gen2 shock???
Worth a try anyway, as it may give you the clearance you need with out having to make anything.

I did try that but no good . Side by side there is very little difference .

Worth a shot.

So what difference is there between the two ?
Is the gen2 lever longer than the gen1, or the other way around ?
If the gen2 is longer even by a little bit, it may fix the problem I've got with the gix1000.
Could you measure the two, and tell me the difference if they're both out of the bike's, if they're still in situ, don't worry about it.

The gen 2 is about 30 mm longer it is also is a bigger shock over all . Much stronger looking with more oil inside by looking at it .
The bottom U section is quite long . I redrilled the hole closer to the shock body and managed to get it to fit my Gen 1 .
I had to file a small amount off  the knuckle and rotate the spring to get clearance . A bit fiddly but a block under the tyre gave me a good idea where I needed the new hole position .  This way I can always refit the Gen 1 shock if I need .
Did you pick up the crate ?

Sorry Gus, I was talking about the difference in length of the lever arms, not the shock length between the Gen1 and the Gen2.

There is about 5 mm difference . If you send me the size and model of the ones you have I can work out which one is longer . I have a spare set just not sure which model they are off .

5mm....that sounds very promising.
Mine are all in the bike's at moment, so can't measure them properly.
If the Gen2 lever, is longer than the Gen1 lever, that may make the gsxr1000 shock fit into my other gen1.
I've got about 5mm of miss alignment, so that extra length should be able to make the gix shock fit with out interference.

Bugger ,I had it wrong . A Gen 2 dog bone  is about 1mm longer than a gen 1. And ,about 3mm longer than a Bandit 600 .
I work on , 1mm  equals to 5 mm in ride height though dog bones do my head in . Best way buy far to change a dog bone is weld in hole and re -drill.
Do not ,cut and re-weld .

I wasn't talking about the dogbones, or the shock..
I'm talking about the clevis lever.
This is the arm attached to the frame, that pivots, and excepts the shock, and the dogbones.
If this pivot lever arm is longer on the Gen 2, compared to the Gen 1, this would be enough to fit the gix 1000 shock.

I'm a Boilermaker, so am well aware of the affects of joining and welding, and stress fractures associated with doing so.
[size=48]In relation to modifing the dogbones, anything with this structural integrity, is wise to be made from  a new, one piece of steel.[/size]




[size=53]Rear cushion lever / clevis arm[/size]

There is a difference between them but its so small (1mm at best ) .
The last time I fitted a shock like yours I had to file a little off the knuckle . As did everyone else who fitted one . Could it be the one that fitted straight on
is the odd one .

Question
Mmm....ok...here's the big picture, get some pop corn...

I first fitted the 07-08 Gsxr1000 shock in Gen2. I liked, but then gold valved it,  and put a race tech spring on . I then pulled it out,  and went Wilbers.
Sat on the shelf, until I  bought my first Gen1, then proceeded to fit it to that bike. Just the usual battery box plastic cut, and dogbone alteration, but defiantly no other structural alterations. The tolerances are close, but never any fouling.     "Like a glove"
Now with a futher Gen1, plus the same standard 07-08 Gsxr1000, it fouls on the knuckle, and inner front swing arm. 
I've measured both by calipers, and the outside diameter is sweet fuck all difference, and still measures the same eye centres of the shocks roughly 312 eye centres.
I'm scratching MY head.
I do like the idea of a different cushion lever. Not only for clearance, but for stroke of swing arm travel.  A little bit longer cushion lever, should equate to longer swing arm travel,  but hopefully without over stroking and fouling on mechanical advantage. Plus the shock being multi adjustable in damping, can be utilized for stability.
That's my experimental plan at the moment. Chain slack would also have to be taken into consideration.
I know GP bikes do, or have changed this mechanical advantage to suit certain tracks they go to.  Flat, as opposed to woops in the track surface.
Finding a compatible donor lever could be another story though. Although the early Bandits are a parts list of so many early bikes, it might be possible.

Or ,you could just buy a new Haygon shock that fits . I have tried a few different used shocks and never had much success . The Hagon shock fitted straight in ,was new and never gave me any trouble . In fact ,cost less than a service on my Ohlins .

True, that could be done.  Dollars I really don't want to spend on this bike though.
I absolutely love the Gsxr shock in my other Gen1. The damping is near perfect. In fact, I  reacon it corners as good as my $1300 Wilbers on my Gen2. Extremely stable. 
I've recently just had my Wilbers serviced, I know what your talking about in terms of price. If I had the gas, I would have done it myself,  but I had to also get it done as part of factory warranty services.
