Wow. What a mess, but all in all the cap was probably going to be toast one way or another. I say damned good job. You got it done, ME; have a well-earned beer.

Thanks Primate, a bloody mess alright.
I've also discovered a broken rivet which holds washers/baffles etc in place in one shock.
This after getting the shocks dyno tested by Ikon and them saying all that was needed was a seal kit.
It's a blind rivet, I wouldn't know where to get the right one other than taking the mess to Ikon.
What a debacle.
I'm going to look at new shocks.

Those Gazi shocks look interesting Jeff. Gazi, YSS or Ikons? Other local alternative?

This thread hasn't helped my confidence in doing new seals & oil for my old Konis. They still work ok but I've had them on a bike for a couple of decades and I'm sure they'd be better for it. I have the seals. What oil did you get in the end Jeff?
Seems I remember Charlie & Pete had an easier time doing a pair recently?
I'm currently using the YSS cheaper version. They're ok for use on good roads but struggle when it gets bumpy, so I'd like to do the Koni's eventually.

Gidday Steve,
looks like new shocks will be the easiest and quickest way to get on the road next friday.
Maybe $450 for another pair of Ikons.
I don't want to hit those out back roads with totally worn out shocks. 75% worn out ok, but not 95%
As far as rebuilding your shocks, getting the nuts/retainers off is potential problem No.1
Finding a tool to get them off, No.2
Finding other problems No.3
A quality ten wt. fork oil has had a couple of positive votes

At least you get a pair for that.
I'm lookin at over $500 for the mono shock on my Honda......... and it will need a $150 service annually.

What is strange about this broken rivet, is that the washers held in place by the rivet seem to be blocking off all these holes.
One washer under the rivet on the outside, and on the inside, three washers. Two flat ones with a wave washer between them.
The flat washers on the inside cover all the holes. The rivet seems to have the inside and outside washers drawn together tightly. I don't get the purpose of the wave washer? It is difficult blow air through the tube with the washers in place. It's not quite airtight, but not far from it. It seems odd with all those holes. Perhaps these tubes are used for other models as well and are superfluous on mine?
I can ask at Ikon I spose.

Perhaps a method of hydraulic baffling... or baffling the non Ikonsmen ?
... and here I was thinking I might pull apart my Koni's

My guess is that it has to do with high and low speed compression damping.
When the shock moves up and down slowly, over whoops or jumps on an MX track for example, you want fairly firm compression damping to avoid bottoming. But when you hit a rock you want the wheel to be able to move quickly up and over it.
That washer is spring steel and causes a lot of restriction as the oil passes slowly by. But when the wheel takes a hard hit and the oil pressure builds, the washer flexes and allows more oil past it.
On modern shocks (and probably Ikons) there is a "stack" of washers of different diameters, that can be changed out to give the desired ride qualities.
On really expensive shocks, usually remote resivour, there are 3 adjusters, one each for rebound, low speed and high speed compression.
