Timing?

[cam2]

what is the real deal on advancing or retarding your timing? which direction gives you better top end performance and which one gives you better low end performance? how is the stock cdi designed to work, does it advance at certain RPM's and retard at other RPM's?

thanks.

well i can at least tell you how the timing advance on the cdi box works

 

it has to do with the wave signal that is produced by the exciter at the flywheel

the excitor produces an AC voltage signal

as the rpm increases the voltage of this signal will increase but the frequency will be the same..........if you draw it out as a graph with the bottom being crankshaft rotaion angle and the vertical colum beign voltage of the signal.............

 

its hardto explain without a picture and if i knew how to post one i woudl draw it up for you and you would see what i mean .........maybe i coudl draw it up tonight and email it to you??????

 

 

anyway the igntion box is set up to fire the coil when the signal is at a certain voltage

so as the rpm increases teh time at wich the signal reaches that certain voltage will be sooner

when the ignition box reaches a certain set voltage for the trigger signal it will stop advancing ...........

 

 

 

i guess you just have to draw it up on paper to see what i mean its just like a sign of cosign wave that we used in math class in high school...........

On a banshee, you want to advance it to make more power. This is a pic of how I hogged out my stock stator plate to get about +4 to +5 timing advance.
