Fitting a Corbin ta GS1100/1150
Having browsed this thread a couple of times.............I'll give you my thoughts, having fitted the same Corbin to 4 different GS's of the above types
Corbin Front Seat
Having fitted the wire rack to the underside ........ slide the front of the wire rack into either of the front serrated seat height hooks (depending on whether you want it on the high/low position) and push it 'home'.
When it's in position, hold the rear of the front seat and slowly pull it rearwards, whilst applying slight downward pressure, this will then make sure the rear of the wire frame, engages the front seat locking latch mechanism.
When the front seat has locked in postion, check the front hasn't slipped off the front height adjusters.............if it hasn't.........
bingo you're 'home & dry'.
Corbin Rear Seat
Leave the 'garden hose' on the front locators.
When fitting the rear 'U' latch take (4) 10mm nuts.
Firstly screw (2) of the 10mm nuts all the way to the top of the threads to the seat base.........this gives you the 'right spacer' ............
Then attach the 'U' latch and then bolt up the second pair of 10mm nuts and tighten up.
Now you have the latch at the correct height to engage with the locking mechanism for the rear seat catch.
Slowly engage the front two prongs of the rear seat and slowly push down the rear 'U' catch onto the locking mechanism, until it clicks into place.
No need for 'magic fingers'
Job done.
However a word of warning.........
Tape up the top face of the rear rack and the sides, especially where the front seat 'rubs' against the sides.
Plus fully tape up the grab rail on all sides and top.
I use silver gaffa tape...........matches perfectly to OEM paint and stops the Corbin rubbing away all the OEM paint, which it will do very, very quickly (have a look and see)
These seats are heavy and can rub the rack badly.
Re-tape and replace at regular intervals...........Corbins can rub through strong Gaffa tape, every couple of weeks to months.
This is the price of supreme comfort
