Recently I decided to check the ignition timing on my commando 750 as I hadn't checked it in many years and I felt the timing could be out
I have an Alton starter so no timing marks
I set the motor at tdc and made a mark
And then another at 29° BTC
When I checked with a strobe lamp I found the advance steadily increased until around 3000 rpm where it stops and as revs increased to say 5000 it suddenly advanced again
It was around 30-31° at full advance
There was nothing steady about the advance curve
This was with a Rex's speed shop replacement cdi
So I tried plugging in an original Lucas CDI amp with the same results
Is this normal for Lucas Rita would anyone know?
