There's one thing about that which makes my teeth itch - and it's the same on yours...
Sort those front mudguard mounts out! Get hold of a set of older front hubs, with mounts for the inertia dampers on. Then they'll turn with the steering... I can put you in touch with a likely suspect, if you want.
yeah yeah yeah... all in good time... that's lower down the list.... Sort those front mudguard mounts out! Get hold of a set of older front hubs, with mounts for the inertia dampers on. Then they'll turn with the steering... I can put you in touch with a likely suspect, if you want.
First off the bat, my new steering wheel came today!
Its surprising the difference in size! New and old.
Its slightly dished too which brings it closer to the body, again making more legroom, where the old one was flat.
Much better on the old leg room!
Went out fir a quick drive and couldn't believe the difference it made! The steering was less wishy washy and generally more feedback!
Next interior mod is to make the seat comfy!!

Here's a little video on start up/rev.
It will be going as part of a longer video when I eventually get around to doing one properly....

I think it sounds pretty good!

A few Updates:
I've managed to fabricate up a new breather arrangement and it looks a lot neater and MUCH smaller than the ruddy great big bean can on the front. My only problem with it is that it uses a brass fitting, a small length of copper pipe, a bit of hose and a couple of jubilee clips. To help hide all the detritus going on underneath, i've wrapped it in some black tape - i'm sure i will come up with something more permanent when i can be bothered.
The only flanged fitting i could find was a tap wall fitting, so i've drilled this out to 12mm:
this will be be attached to some braided hose and will lead to an oil catch tank. This can't be fitted until that big ugly carb is out the way though...
One of the guys on the builders/owners forum was changing his set up, so i've also purchased his twin carb set up too. That arrived today so no photos yet. I might get a chance to fit everything next week!
i also noticed that the gap between the aero screens seems to turbocharge cold air straight into your face and adds a lot of buffeting so i've bashed up a bracket and a rough bit of plexiglass to help with that. I will get a bit of plexiglass cut properly as its almost impossible to get it perfectly symetrical with a jigsaw and a file

That "ruddy great big bean can" does a lot more than just route the breathings. It's got a one-way valve in it, which keeps the crankcase pressure negative. Remember, you've got big changes in crankcase volume, due to both pistons going in and out at the same time. A one-way in the hose will do the job.I've managed to fabricate up a new breather arrangement and it looks a lot neater and MUCH smaller than the ruddy great big bean can on the front.

Yes, that's why there is a one way breather valve on the brass tap elbow! Today I had the pleasure of visiting the Grinnall showroom and workshop and chatting with Mark Grinnall - the founder and brains behind the operation.
Truth be told, I've had my eye on a grinnall scorpion ever since I started looking into 3 wheelers at the age of 17. When I came to sell the Lomax earlier on in the year I wanted to replace it with a Scorpion, however the OH said they were ugly and the pembleton came up at the right time at the right price, and was an excellent build (barring a few issues - documented earlier in the thread).
Mark has 5 or 6 Scorpions in at the moment - some customer cars, others for sale ranging from £7.5k-£20k for a brand spanking new unregistered top of the range weapon. At 6ft 5 (very long legs) and rather doughy, I knew shoehorning myself in was going to be the decider. I don't fit. Even if I lost some weight off my arse/hips so I could really get into the back of the seat my knees would still be hurried in the dashboard roll moulding...
Whilst I was there the wife did take a fancy to the trikes though and it didn't take much persuasion to have a sit on one. My god they're nice machines! Brilliantly built and put together, incredibly comfy and solid, yet not a bit intimidating. Again there were two to choose from, the new triumph Rocket III, and a BMW R1200C. The rocket felt a little big and heavy for a first trike, but the BMW was lovely. Mark was in the middle of prepping a competition bike, so I didn't want to outstay my welcome - but he has invited me back to have a proper look at the trikes and have a go on a BMW one. I must say - I am VERY tempted - although it would mean getting rid of the pembleton... :sad:
(apologies for the stock images - I totally forgot to take them whilst I was there)

So I've test fitted the two keihin Honda carbs and plumbed them in, and also fitted my home made breather arrangement.
Once it pumped the fuel through and i adjusted the idle, it started and ticked over well, although it seems a little rich, so they will need some fine tuning. I still haven't fitted the modified accelerator cable yet... Or attached the Bowden cables for throttle or choke.
After this is done my next job os to relocate the oil cooler!
Ive been playing around with a location further up and back just in front of the starter motor... I'll need to make up a bracket and try out with my spare one...

Since getting the pembleton I always knew that something wasn't quite right with the suspension set up, it seemed to heave and roll a fair amount. The other week I had a quick glance underneath to check how far the suspension stops were off the plates that they react on.... the stops themselves were fubar, so there was nothing to stop the suspension travel. It just kept going until the spring rate overcame the inertia.... no wonder it rolls....
I could see from looking at them that the ones fitted were the cheaper copies that have a very poor reputation, so I splashed the cash and got some new hight quality ones ordered...
Bit of a pain as its an arms off job...
Technically you don't have to remove the wheel, but it makes it a lot easier to do...
First off removal of the end plate that the shock absorber mounts to...
With that moved out the way, underneath is the ring nut that holds the arm on. With the split pin removed, a couple of blows with a screw driver and hammer is needed to get it moving, then over to the special tool to unwind the rest of the way...
After a some jiggling and pulling I realised the arm wasn't going to come off that easily, so I made a very quick and dirty arm puller (same principle as a caliper wind back tool) out of a bit of plate and a nut+bolt...
A few turns here, then rotate, then turn and rotate, soon had the outer bearing and arm off...
The swap from the old bump stop to the new probably only took about 2 minutes here... just about big enough for athe socket
Old bump stop+spacer
New bump stop+spacer
Reassembled, using a wooden drift to tap in the bearing and re-seat it...
Put everything back together with a new split pin and do the other side...
The bump stop on the other side was a little easier as the arm just pulled. Off straight away and I didn't need to use my improvised puller... the old one was just as ruined though....
By this point I only had about an hour of light left and I still needed to put everything back in the garage, so I only had a 5 minute drive around town and around some mini roundabouts, but the difference is night and day, it gets to a point where it just doesnt roll any more and gives you the extra confidence to throw it about.

One of the guys on the forums I frequent was selling a couple of MGA 40 spoke wire wheels, one LH splined adaptor, various spinners etc.
I've snapped these up and despite looking a bit crappy, all the spokes are tight with no breakages and they run true with no dents. I've had a quote from a local blasting company for about £40 for cleaning them up.
I've already ordered a matching adaptor for the other side. Once I've had them cleaned up and I've painted them I'll need to order a coupe of tyres and tubes. The speed-discs are nice, but wires just look right on a Pembleton.

I got up this morning and looked outside, then looked at the forecast and thought bugger it, I'm driving the pembleton to work today. My commute is 57miles each way if I go the a43/a45/motorway, or if I wind across country its about 45miles, but a little slower. I opted for the country route today. :biggrin:
First world problems
And now I'm sat in the garden reading a book enjoying a beverage....
Its a tough life, but someone's gotta do it

I've been in that carpark once or twice, if it's the one I'm thinking. Plenty of interesting metal lying around IIRC, and not necessarily stuff that's produced inside!
I couldn't possibly comment! Shame that there's usually at least 10-15 vehicles waiting to be crushed though!
