Matris Steering Damper fitting

[tassieduke]

Hi all,
Has anyone fitting one of these to there bikes? (mine is a S4) step one is to undo the dome nuts that attach the ignition key assembly and fit the pins.
My problem is that the dome nuts,don't come off they appear to be a one piece bolt with a dome nut on top,not a bolt and nut 
Any help would be great, expensive paper weight if I can't get it to fit

Your ignition cover dome nuts might be slightly seized to the bolt, possibly because they were over-torqued at some point or became corroded?  Were you able to fully remove the bolt?  If so, maybe some vice grips on the shaft of the removed bolt will allow you to remove the dome nut.

Pull up the parts diagram and have a look at the original setup.

Been a few years since I installed my Matris damper, but I don't recall any difficulties.

I was able to get mine apart.  If not you can just get a new set of studs.

I put blue locktite on the bottom when I reinstalled them so I wouldn't have the same problem again.

I can get the bolt undone there is no corrosion evident.
It just seems that it is essentially a bolt with a dome head.
Tried the vice grips already but no go
The top of the dome nut has like a ball in the middle,sort of like when you compress a pop rivet.
The bolt itself doesn't what to come out of the cover either.
I have some photos but cant work out how to put them on here.

Yeah I got it to work

it looks to me like you have unscrewed the whole stud and nut as opposed to just the nut holding the cover on. looking at it from here that larger round flange section is the stud, and is meant to stay on the bike and hold the ignition key setup to the bike while the dome nuts are meant to come free from the stud and allow you to remove the cover by itself. i would endeavor to remove the nuts from the studs, and as said above use some stud locker to glue the studs in again just to make things right.

maybe there is a bolt head on the top side of the studs larger round flange that you can get a spanner onto and then undo the nuts, otherwise it may be a matter of a vice or vice grips onto the round flange section..

either way i dont know the matris top mounting brackets as i run a side mount damper, so as long as you can get the mounting brackets on correct from where you are then your good.

Will give the vice grips another try,let you know how it goes.
Thanks for the replies

All done,still could not get them apart so cut the bolts got new union bolts and went together in about 5 min after that.
