koni shocks rebuild...

Does anybody know of a shop that will rebuild my Konis for my 1982 BMW R100S. The ones I have are about 11 or 12 years old and are feeling worn out. Bob's BMW told me that the cost of a rebuild was not that much different than new shocks, either Ikon or Works.

Should I just buy new shocks, or can they rebuilt for less than the cost of replacement?

Any help is appreciated. And yes, this is my first post.

There is a guy who advertises regularly on ebay who claims to rebuild KONIs better than new.

They could be pulling your leg. I recall a buddy who bought a rebuild kit from Ikon about 2 years ago for less than $50. He did the rebuild himself and is still happy to date.

I suggest you shoot an email to Ikon Australia and check.

Coincidently I rebuilt a pair last night. Very easy to pull apart. Has yours just lost the damping or is there a definate leak. Mine just needed new oil in the dampers - 85cc of 5 weight oil.

The IKON parts are straight replacements so you can buy parts for your Konis from the IKON distibuter.

Isn't there some version of the Koni that is not rebuildable? I thought there was some issue with the later shocks being welded shut. Maybe I'm thinking of something else.

I've rebuilt the dial-a-rides and the earlier versions using a spring compressor and a pair of pipe grips.

leaking and weeping...

There is a small leak that Nathan at Boxerworks pointed out to me. Most notably is the squishiness of the rear end when riding 2 up which wasn't there before. And I keep it on the highest setting now.

What should I do? it looks difficult to rebuild.

To be honest if you don't feel confident with taking them apart I'd buy another set for $300 and forget about them for another 10 years or so.

However, if you are comfortable with jumping into the unknown with a spanner:-

I have a home made spring compressor that makes it easy. Most auto shops have them.


Pipe grips make easy work of undoing the nut.





Just drain the oil and carefully fill up with the new before putting it back together.

I hadn't had that damper apart before. it took longer to take the photographs and post them into this thread than it did to change the oil.

The leaking seal makes things a little more difficult. but you can buy the parts from you IKON distributor.

So, those dampers aren't filled with some kind of gas under high pressure? I always thought they were.

If it was it's not anymore

They use gas in some shocks to stop the oil frothing.

what next...

It appears as though everything points to a new pair of shocks. What to do with the old ones? There is a big hunk of metal in those springs.

Also, other than Ikon, what brand of shocks would be best, without breaking my bank? I ride 2 up with my wife a lot, usually with factory luggage. I like to ride sporty, but I am by no means a knee dragger or wannabe speed racer.

If you decide to replace rather than rebuild, I'd be interested in getting the old ones from you.

I suppose Ikons would fit the bill but are rather pricey at $400+ a pair but i don't know of other competent brands.

I would go for the stock shocks. They are still available from BMW and, AFAIK, at a reasonable price. I used them for quite a while on my TIC until they were really worn out, then replaced them (since non-repairable) by the IKONs.

If you do not like rebuilding the KONI/IKON, sell them to a good home
