BOOOOO
Hi mate good to see it back together and its looking sexy!!
The symptons ring a bell as i had loads of trouble with my coil earth and ignition in general.
Make sure the section where your coil sits is cleaned up as the earth here needs to be good as we all know.
There is a small single black wire that is earthed to the coil base plate and i added a second earth strap from this to a spot near the head light which has helped no end and i havent had any problems with it since !! ( So far lol )
You have to remember that 20 year old wiring loom isnt the most reliable so the best you can do unless you replace it is to try keep the earths and connections clean.
Il check mine tomorow and take a picture of my coil wiring if needed.
Good luck
