okay..

now the silly question...

can sum1 tell me which one is the
Volatge regulator and the CDI?

is it Voltage regulator is the solid plastic with 3-8 pins, or the one with the metal cooler fins?

i'm miserable in searching the way to fix my bro's et4...

which it all happened when i starts the scoot while holding full the throttle (my bad, i don't know this will ruin my ride since then)...
it's starts... then the ram decreasing till it's like you switched it off... that was the last day the et4 started n dies (about a month ago)...

now, when i switch on the et4;

-headlight and turn signals working..
-the starter working (it tries to start) when i press the elctrc starter button...
-horn r loud as usual...

further check;

-no spark when contacted the spark plug to metal surface (spark plug is in good condition, confirmed)
-no spark at the 2 cables
that connected to the coil (i try to connect each 1 of it to the metal surfaces then start)

n my problem;

-i don't know what i have to do other than changing the Voltage regulator or the CDI.

any recommendations for my problem.. thank you alot guys...

and for your info, i stayed in Malaysia which is very hard to get the piaggio,magneti marelli,etc spare parts... i just can order 'em at superbike service center which is if i ordered wrong.. it can consume alot of my money...
