haha sounds like you have most of it covered. What will you be doing with the rear suspension?

General Putting a bike engine in a Sei?
Rear suspension is actually cento front suspension. You can see the lower arms and the turrets in the photos with the engine in position.
Suspension wise it shouldn't be too bad if a little soft because its got the standard springs still and the bike engine with extra reversing bits should be close to the 1108 engines weight. The front will be a different matter entirely as it'll be about 70kg lighter and preload will be all over the shop too. I'll worry about that when I get it on the road though, I can then go shopping for some aftermarket shocks and springs to sort it out

This is the area that interests/scares me most. Any provision for adjusting camber/castor?
Surely there are metal stockholders somehere in the W.Midlands still? There are 2 within 5 miles of me in Liverpool!

There are a lot of scary bits from my perspective, suspension is only one of them
I'll have effective another set of steering arms on the rear so I'll be able to adjust toe. Camber and castor will be fixed. I've tried as best I can to build the rear matching the same setup as the front. I know car have different front rear setups to front. Ensuring negative camber on the rear might just mean some grinder/welder adjustment of the rear lower arm mounts. Castor I'm not desperately worried about as I can adjust toe to correct any crabbing and as the rear isn't steering I don't have to worry about it pulling beyond that.
There are many steel stockists in the midlands, but I simply picked the cheapest online one at the time for the quantities I was ordering and got them to deliver it, meant I could get 6m lengths delivered rather than chopping them up to sub 3m lengths to fit in my car. Delivery being free from most of them so it really didn't matter to me where they were in the country.

Now that's a really frightening idea!
I suspect that one day it'll end up with double wishbones and fabricated uprights, but the idea of getting it up and running ASAP can't really be faulted.

I want one LOL
Hope you get it through the sva ok
They can be a bit mean
Rear engines are the way forward

No idea if the 126 setup would work, I couldn't even tell you what that looks like, I'll kick myself if it turns out it would have massively reduced my cutting about of the body
But the sei front suspension cost me £45, I'm reusing the driveshafts and differential was 6 speed one (£12) with crown wheel removed, so this has cheap cost on its side and the parts still being cento/punto parts bin. I'd like to keep specialist complex parts to a minimum.
If this setup proves to be rubbish then what ever is causing the rubbishness will be ripped out and redone with more thought :idea:
The basic principle of mac struts all round is sound, my old Mr2 had it and that was a peach to drive. The devil is in the detail though. Does anyone know of any good checks or rules of thumb to apply when setting the suspension up or building your own?
I am worried about the SVA mostly because I have no clue about the process, I've got the latest IVA manual for bedtime reading but it all seems fairly straightforward in terms of actual build, its the paper work side that will get interesting, especially emissions, bike emissions regs are completely different and what with it being a 2000/2001 engine I'll have to get some end cans with cats in them for it plus a cat friendly tune, as a minimum borrowing someones power commander and laptop
Rear engines are good but from previous experience are a b*t*h to work on, this one should hopefully be a bit better by being a tiny engine
Lots of good stuff in the Staniforth books. Also some good ideas for a double wishbone rear set up in the Haynes Roadster book -- you'd need, I'm sure, to change the length of the arms, etc. but all pretty simple -- the uprights are just a welded mild steel fab job.
Nowt wrong with Chapman struts, but double bones allow a fair bit more adjustability.

Thanks. I assume you mean this one in particular?

I'll put it on my list to santa
I did look at doing the haynes roadster setup but it looked like even more fabrication than what I've had to do for what may turn out to be no benefit. I may well regret that decision when it doesnt go straight and need to adjust the rears somehow, but I'll cross that when I get there. Probably by completely space framing the rear end, at the moment only the boot floor has been chopped out.
Hmmm something to think about while I'm making the engine mounts which looks to be a very dull job indeed.

That one, and there's the Race and Rally book (less theoretical, more drawings), too (often s/h on fleabay, but still in print, I think).
But, yeah, I'd try what you have first, see how you get on.

Update time!
No the project has not died! I've just been rather busy with redundancy plus moving house (still not quite finished that bit).
And before I put up the pictures I'll just say Fingers you were right about the suspension being more difficult than I thought, it still needs serious work
Lots still to do but I reckon its about halfway there now

crap to hear about the redundancy
but nice work, keep it up

Redundancy problems were sorted last week, I have a new job starting around the end of the month but its in Liverpool, hence the move.
mint project!
i was looking at this hows it going is it any further on or did it stop in its tracks

wow i was living in st.helens for 21 years waiting for another seicento mad person and here you were all the time... now i live 3hours away :-(
would love to see how it turned out.

I wouldn't lose sleep on it, I only moved to st helens about 3 months ago.
New job, new house, trying to sell the old house, have all taken their toll on the project but its still moving, I won't be letting it die!
I'll stick up some pictures when I get chance, still got the exhaust and the wiring to do before I can run it up. Plan is to have it driving under its own steam on track by end of August. Then it'll be IVA over winter...
