How to fit a Gyro on an internal headset (pictures incl.)?

Hi all

I would appreciate some experienced guidance please, I bought a Salt AM Gyro but cannot see how to fit it. It came without instructions and I am new to BMX. I have included pictures and labelled the parts. I am now not sure I bought the correct gyro?

Below is my headset on which I would like to fit this, but it seems too loose/big for my bike. It has the wholes for the gyro tabs. I have loosened the existing parts just to show what it currently has. It doesn't seem to fit with these parts nor without them:

I appreciate any suggestions.

Thanks

Snip.

Thanks for the replies, OMGitsMe and Mack_turtle!

EDIT: Thanks Pickles, just read your reply when I posted. So it should be OK even if loose?

I have now installed the gyro tabs and placed pieces A and B where I think they should go. See pictures.

If I balance part A on top the gyro tabs, it looks OK, but as you can see in the second picture, part A is actually quite big and would hang loose if not balanced on top. I guess it should be fine when I put the break cables in place and it all pulls tight? What do you think?

So my questions are,

1) does the size look OK or is part A too big?

2) Is the other part B correct?

All of this seems to fit over the existing headset washers and nuts.

Thanks!

Second picture below, the gyro part A is loose if not balanced on gyro tabs, I guess it needs the cables to hold it in place, but it looks too big to me, like it will rub when riding:

Thanks again Pickles. I will experiment further and feedback to hopefully confirm it is working well :)

Thank you Mack_turtle

Quick update...

Cables are now in place and it appears to be working except for a frustrating couple of millimetres of slack cable at the break leaver. The tightening nuts are fully out from the stem up, so I think I will need a thin headset spacer, as you suggested. Top Gyro plate is flipped as suggested.

My impression is that there is probably some extra cable because of the smaller integrated headset compared to a larger headset which would tighten the cable more naturally. 

I will test it out on the street and see if it improves before adding a spacer. :)

Close up on finished gyro in place with cables. Should it help anyone to compare notes in the future:

Great Forum by the way, thanks for letting me join! 

Well it is all your contributions which are helping! 

OK, so it survived the street test so I will keep going until I get around to buying some cable karps (I didn't even know they existed!  so glad for the suggestion).

I thought of cutting a longer piece of the black cable cover with an extra 1 cm to force the break cable to use that extra 2 mm slack, but I cannot see a way to unscrew the gyro splitter cylinder system at the top to put the cable cover over the existing cable without cutting it. (Hope that makes sense). So I will enjoy it as it is for now. :)
