I had a look today at one of the old Konis I had taken apart because the seal had burst. If your shocks are built like the old Konis, the top mount is screwed in the normal r/h direction onto the threaded part of the damper rod. You could email Ikon and ask them if your shock is assembled in the same way. If it is, then the damper rod has rusted into the top mount and will need some rust penetrant and maybe a bit of heat. Is the top mount steel or aluminium?

Sorry for the delay replying. I ended up buying some Ikon 7610s with Adjustable 3-position spring tension and 4-position hydraulic damper and the No.231 spring.
To my shame
I haven't bothered doing static sag etc and have ended up guessing the settings. I found that with the spring on it's lowest setting and rebound at No.2 that the Norton was very bouncy two up on the back roads, so I re-set to the second increment for the spring and the rebound setting on No.4 and that setting has nearly sorted it. It's absolutely fine on main roads but still very slightly bouncy two up on the back roads.
It's maybe because I've tried to sort things through "the seat of my pants" instead of measuring sag etc to try and work out what's going on that Im not completely happy with the Ikons, but I am happy enough now and a lot happier than when I originally posted. Maybe I'll look into it a bit more tomorrow now you have asked the question?

That would be much appreciated, thanks!

On my old Koni shocks (same as the Ikons) I have the top adjuster on the 4th setting and the spring set on the seconds hight for solo riding but when i have the misses on I adjust the spring to the third setting and all is good, but when I rebuilt the Konis I replaced the oil with 10w oil (they come with 5w oil) so now I run the the spring on the first setting and the damper on the third setting for the same effect.
Hope this help, you just got to set it up for your riding style. It all depends on your weight as well and might need a heavier spring.

I haven't got a definitive conclusion yet, but I have done a static sag test tonight and I have to have the spring on maximum pre-load to get the static sag down to less than 10mm, so | will look at getting some stronger springs over Winter. Ikon recommended in an email to me last year to use 204's and I've got 231's on as supplied by Norman Hyde. 204's are only slightly stronger 18-33 against 17-31 for the 231's.
To be continued :lol:

How much did they cost you. Apparently Ikon make a basic non adjustable type for a lesser price. If you have to set them at the higher setting, maybe adjustable ones are not needed. Curious about the price though as I need to replace mine very soon.

The 204s may be only slightly stronger but they are 235mm long as opposed to the 231s which are 205mm long. That's 30mm extra preload. Good luck fitting them by hand

Holland Norton Works sell the 7610's, but I don't know which springs they fit. Price was similar to N. Hyde but buying from N. Hyde saved me converting the GBP into Euros, although when I bought my FCR' carbs from Holland Norton Works I used a company called "Transferwise" as recommended by Constant Trossel HNW proprietor to send and convert the GBP to Euros and it cost me about £12 gbp to send approx. £1,200 GBP as Euros, a big saving from what the banks charge. So on a smaller amount it would be less.

Last time I changed some shock springs (the Konis on my Guzzi) I cobbled some contraption up using car spring compressors but they were slightly big for the job. This job is one reason why I'm not rushing into doing it.
IIRC £333.60 incl p&p.

Just bolted my new Ikon 7610-1653-SP9's, rode only 5 miles.... what a difference over the Taiwanese EMGO's... (I know, I know... 
) Lowest preload position and #2 damping to start, clicked up to middle preload. Wish I hadn't waited so long :idea:

My bike has them too. I've only ever had Koni/Ikon rear suspension so don't about the other brands but would not consider them based on others' feedback. I also use my now refurbished 7610-1277's (1" shorter).
