I have just finished one for a forum member Bill he said he is cruising at 70 and to be honest I had his timing set on the safe side.
You should be quicker than you are it maybe worth just swapping lumenition units or sending me yours and the optical pick up to test.
I now have lumenition test set up and test boxes.

Hi Paul
I didn't realise you repaired Silks. I'd be happy to have you look at it, there's no rush as winter is coming.
It's a mk 2.
Just for info, I've:
Done a compression check (good).
Checked ignition timing and moved it a bit advanced and retarded of standard and checked mechanical A/R.
Swapped (unsuccessfully) to Boyer, now back with Lumenition.
Rebuilt carb with new jets.
Tried a larger 36mm carb.
Cleaned and repacked exhaust.
Put in new crankshaft oil seals.
Checked for inlet air leaks.
Had bike on dyno (31bhp and running very slightly rich). I would have expected this to be enough to go faster, even though well short of the claimed bhp.
Checked chain tensions and brakes for dragging.
Checked speedo reading against gps on my phone (getting desperate but speedo was surprisingly accurate).
