On stripping it struck me that the electronic kit has been on over 20yrs without fault.
It was a genuine SIL kit sold by SR when the AF ducati kits stopped.
Give it a thorough check and all the wiring, soldering, etc is still spot on and checked the flywheel again spot on -both look brand new (external of flywheel excluded)
They were rewired before been sent out by SR.
I remember buying it and fitting it and just followed the instructions....using positive stop and a simple timing disc - It was th first lambretta I had ever timed from scratch
Things were genuinely better in the old days..........

If it continues like this it will see me out, good old SIL (RIP)
