Interesting info .The intake valve has an opening point and a closing point.
The exhaust valve has an opening point and a closing point.
The INTAKE CLOSING POINT is the most critical valve timing point because it determines the powerband of your engine.
The intake closing point can be changed by: 1- adding or subtracting duration 2- changing the lobe separation angle 3- advancing or retarding the camshaft 4- changing the valve lash
Earlier intake closing = more POTENTIAL bottom end power
Later intake closing = more POTENTIAL top end power
More lift = more POTENTIAL power at any rpm
Less lift = less POTENTIAL power at any rpm
I use the word potential because every combination is different and anything can be taken too far.

it will be a homemade ignition, my friend is now adapting it, we have the first prototype on which we are testing. It consists of a control unit with display, a sensor for the flywheel, and a coil for the moto scooter, it requires power from a battery or an integrated generator coil.I would agree . the mongoose would be my choice .
What is the source or manufacturer ?
The ignition sounds interesting keep us informed if it comes about .
The single fire ignition modification on the Harley v twin worked good .While you are at it, why not make it fire on the power stroke only.
Best, WP
In the 80's they had a local class here; any 5hp flathead, stock bore & stroke, stock valves, cam lift rule, carb bore rule.The single fire ignition modification on the Harley v twin worked good .
Any chance of a schematic for this digital ignition .Passed the tests, the ignition system is working. It is necessary to select the optimal angles for ignition.
We have made 3 prototypes. 2 of them are powered by a flywheel magnet. And we made one to read the steel plate on the flywheel. And during testing we encountered a problem, the system with a magnet failed, a high-voltage transformer burned out in them. And the System on a steel plate is still working, but we noticed that the angle that we set and the angle according to the straboscope are slightly different by about 5 degrees.Any chance of a schematic for this digital ignition .
the module has buttons and a display, where we use the formula to calculate the constants depending on the position of the sensor and the flywheel diaseter. for each motor, its own values are obtained. then we set the angles for different revolutions. Yes, the entered angle and the actual angle are different, so online tuning is required on the running motor.OK
so you have adaped various components .
the control unit isthe key component .
a control unit with display , and adjustment , where would that be sourced ?
