Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Suplex fitting and first impressions

Arizona is "ice tea" territory, especially at this time of year. The period of "100 days of over 100 degrees" starts around the end of May. Everyone who can flees for cooler climes. A summer in Phoenix would make a cooling kit a " must have" upgrade....:)

But it's a dry heat...

I'm guessing that both a hammer and a large blunt screwdriver have been deployed Peter.

A plastic faced hammer may well have been involved if you get my drift, which was also involved.
It's not proper engineering without a hammer, a hammer of course being defined as "anything bigger than a screwdriver"

Another definition is "a Coventry screwdriver".

Deft use of said screwdriver would be "the two thou. tap".

Its a Birmingham Screw Driver not Coventry. Incidently at the Black Country Museum they have a recreated shop with more different hammers in the window than I knew there were tasks needing a hammer.

Been through a fair few different settings and the best I managed to get the Suplex rear shocks was with the preload wound all the way off against the end stop on the right and the left one adjusted to 5.5mm from the end stop. Assuming the two springs are close to the same rate this actually gave the same load on each. Not having a shock dyno to measure things properly this was measured using a feeler gauge between the windings on the low rate section of the springs; 12 thou unladen, reducing to 4 thou with me on board.
At this rather strange preload set up and damping at 42 clicks from hard it was still very harsh over bumps but was no longer pumping down over a series of bumps. It was very inclined to pitch me out of the seat though, even on single bumps.
When bouncing on the rear end there did not seem to be very much travel and it was coming back up quickly but with no apparent overshoot.
Next step was more radical; I refitted the standard rear Spax shocks. Bouncing on the rear end gave much more travel than with the Suplex but again with a decently controlled return to static so I went for a drive.
Result!
What a difference. Over the same bumpy roads and the same individual bumps the car now just rides over them and the Suplex front end is very good indeed. I had been worried that it was the front end improvement that was making the rear feel bad - how wrong I was, it was the rear end being bad that made it feel bad!
Right now my next step is to contact Suplex and ask to find out if I am missing something obvious to also ask the direct question regarding whether any of this production batch of shocks have actually been tested on a three wheeler and whether the spring rates have been checked against specification.
My thoughts currently are that the low rate section of the spring is so soft that it serves no real function beyond being a spacer between the high rate section and the top of the shock. It might do something when coming down after cresting a rise, or landing from a jump but I'm not convinced. The high rate section of the spring seems to be too stiff and quite probably too short to be fully effective.
Has anyone else had Suplex shocks from this first full production batch fitted? As opposed to the handful of pre-production ones that made it out into the wild. I'd really like to hear how people are getting on.

"I stand corrected", said the man wearing a surgical boot. Did they have any metric hammers or were they all Whitworth/BSF?
