Gompy, it works on my scooter

I just made the timer board on a protoboard, and hooked it beetwen the pickup and the CDI, and it works also like this

I have one question, when is the LED lit up? because i saw it flashes when there is no pulse, it seemed like it self triggers?! It can be the problem for the rpm calculatio, and for the fake advance..

maybe it just because the protoboard, i will make it on a panel at the weekend.
