I wired it all up, and had it running . I now have the tank etc all fitted, so I tried it again - but this time, NO spark. It has a new coil and a new ECU. I have an idea what might have gone wrong, perhaps a loose connection - but when wiring up, I wired a lead from the ignitor to the starter solenoid as shown in the diagrams, BUT it only started while the starter motor ran! so I wired that lead to another power source and it ran OK. But I don't like the idea that I have in reality not wired it right, and now it won't go. I intend to re-wire the whole ignition now. I tested the coil, it is OK, so now I will try to test the ignitor.
Keith,
I just went back and reread the above from one of your earlier posts. I'm having second thoughts about your pickup coil despite the fact that it apparently tested OK.
Has the bike ever run except when you had power to that lead between the igniter and the starter solenoid ? It looks to me like that wire supplies the signal to the igniter while the engine is cranking and then is disconnected as soon as the solenoid disengages. At that point the signal comes from the pickup coil to switch the transistor in the igniter on and off.
You said this is a custom build. Does that mean you are not working with a stock wiring harness ?
I found this in the tech section:

yes, I only could get it to run with the wire full time live - BUT when done the right way , it DID fire up, only when the starter was running! It is a custom build, all non ignition I have done from a similar diagram, except I have no decompressor. The rest of the wiring works OK - it's done with a Zenith brainbox , really easy. I am ready to give up and call a travelling electrician to sort it.
Finally got done with the Magneto and ignition pickup remove and replace! Started up and ran fine after putting juice in the battery and charging it for 30 minutes. Looked to be bone dry on gas too, that always helps them run, so I got my mower gas can and filled up for a little test ride in the rain. Took a few pictures under the carport when I got home:

http://www.catoosatrading.com/images/vehicles/cycles/my_ls650/99_savage/The bike ran out really well. At least as good as the old '87 with only 6.5k miles, and this one has 27k on the OD.
Kid (err young man) I got it from said the he "had the head done" whatever that meant to him and his mechanic. I'm hoping maybe they made sure the cam chain was in good order when they did that, but I'll check it soon just to make sure.
Lots of misc. notes:
First, the spots on the driveway are NOT leaks from this bike. Some are from my wife's car, but most is water from my having just returned from a ride in the rain. After riding it hard for 10-15 minutes, and letting it sit for 30, I didn't notice a single oil drip (yet).
Yes, those forks are 4" over, and ~no~ the frame rake (steering head angle) wasn't changed from factory 35º.
However, the rear shocks seem to have been shortened by about an inch. By measuring with a level / plum and a carpenter's roof rise gauge (angle), and by mathmatic calculation, I've arrived at a new rake of 39º-40º and a trail figure of between 6.5"-7" (under 7" for certain).
Anything over 40º rake is considered "extreme" and street bike trail is normally between 4" and 6"... So... by the math, this setup is pushing practicle limits, but it felt real good to me on my little 8-10 mile ride. No mountain twisties (yet) due to rain, just street corners and straightaways. Slow speed handling was really good too, considering the frame geometry. That is with the exception of having to zig-zag back and forth about 10 times in the driveway to turn it around.
I think the five-speed gearbox is probably worthwile
Several small knit-picks: The 23" drag bars are WAY too narrow, and combined with the short stem mirrors, you don't get much of a rear view. Think I'll try my 26" flat drag bars on the super tall straight risers already on there first. Hope all the wires and cables will reach another 1-1/2" per side. If that doesn't work, it will just give me an excuse to try one of the pairs of Z-Bars I've been saving. And those really thick leather grip wraps? Those gotta go. The clutch cable needs adjusting.
Thinking I'll put the big loud turnout on this bike. But the short sportster muffler is louder than the too-quiet Dyna on my '87. I might put the Sporty muff on the '87.
Then there's the custom headlight and o-ring pegs still in the boxs; which have had to wait on the electrical repair. So many toys... so little time 8)
