Got a piss poor turn up at the club meeting tonight but for a nice suprise all 3 of us went around to see a 99% finished Monty Formulae 5 minutes away from the meet.To finish it 100% its missing the fixing that holds the rear of the seat to the ducktail,all thats there is a 5mm hole above an S shaped wire pop riveted inside the ducktail.Anyone got either a sorse for this or at least a description of what it is.What a wicked bit of kit this bike is and its going to end up one suburb away from me.
 
for the mkII monty
there are a pair of fixing screws at the side panel position
and one at the rear
remove the seat cushion and reach into the tail
should be a single bolt to the remains of the steel fender

If you're talking about holding the seat pad onto the tail/seat unit, my Mk. II had a steel Dzus-type fastener that would clip into the 'S' shaped thing you mention in the fibre-glass. I'm told this was not original and I was the second owner of mine so have nothing else to go on. I've just ordered a 24mm Dzus-type thingy to see if it will fit. I'll report back when it arrives and I'm able to check it. Might be a while though.

Cheers,

Simon.

Simon, I've had the same Dzus fasteners on both my MK2 Montys, I reckon they're original equipment.
 
The builder tried an 18mm long Dzus that I had from a fairing I used years ago and he said it didn't seem to work to well,maybe we need a longer one,24mm like mentioned.So they work by sliding down the side of the wire,as a guess I was thinking it needed a slotted bolt that passed over the wire and rotated into a half turn notch in the slot.Does not seem so secure just passing beside the wire and using friction.

Vince , that's almost exactly how they work. They're also known as quarter turn fasteners and are widely used in the aircraft industry due to their rattle proof qualities. Loads of sellers on eBay offer them. They come in various types such as flush fit, D-ring and proud. Some are self ejecting and others are held captive by an inteference fit nylon washer on the inside of the panel.
 
Bob the one we tried was solid with the 1/4 turn set on the outside like the thread on a bolt,the keeper were like a plate with a hole only with a couple of spurs sound like its the wrong type of Dzus,will try goggling.Is 25mm the right length?
 
those sound like camloc fasteners vince
the dzus has a solid body with a slot at the bottom
the slot makes a 1/4 turn with  detent
the wire slips into the slot
the dzus is turned 1/4 and the wire pops into the detent
spring under head of dzus keeps the wire in the detent
 
I goggled last night and yep there are 2 major types,1 is solid and works like a 1/4 turn nut and bolt,what we tried.The second has a slot and acts on the wire what we need,here is a local supplier so thanks for the tips

Hi Vince

My bike is still half a country away so I can't check, and though I have the Dzus I think I have the wrong type as well. If you have found the right type and a supplier, would you post the details?

Cheers,

Simon.
