capacitor

anyone run a capacitor on there scoot like a 1.5 farad i heard it helps stablize the electrical system lights etc.

Why do you want to stabilise the lights? Do you have issues with the lights? Mine work just fine as they came from the factory, cant see any reason to mess with them myself other than for cosmetic reasons maybe.
Chaos is my co-pilot.

1.5F is a _very_ large capacitor in electronics terms, the only way to make it a useable size at 12V is to use a technology that also makes it far less powerful than a good battery as far as I know..  But then again, I've been working in completely different fields in electronics for the last decade or so, maybe I missed some change in the laws of physics  ;D

Anyway, on an Agility the lights are on the AC circuit.... A large capacitor acts as a short circuit for AC (simplified explanation, but still true enough in this situation), so it will stabilize things for sure : your lights would be in a very stable state indeed :  "OFF"  8)

on my scoot the lights are dim at idle but when your off idle (higher in the rpm) they get brighter have recently installed a new stator. maybe i have another problem i thought a cpacitor would help sabilize this!!! any help would be appreciated.

just by-pass the light control module...

Bypassing the regulator won't work since this is a shunt regulator, which is only active when the voltage gets too high... It doesn't do anything at idle anyway... The core of the problem is that the stator coils don't have enough windings to generate 12V AC at idle with a 45 Watt load or so...

There's nothing you can do about it, apart from making your own stator coils with a few extra windings, but then you would also have to find (or build) a regulator which can stand the extra power at higher rpms....

Oh, and if you're really adventurous and skilled in electronics you can rewire everything to a DC-only configuration, which also means you'll have to design a charging circuit which uses all the stator coils for charging the battery, instead of only the smaller coil..

I've been thinking about these solutions for a while myself, but solving this small problem is just not worth the trouble it will take... Trust me, I make a living designing and building custom electronics...

Best solution : adjust the idle rpm somewhat higher (but not so high that the clutch will engage of course), your lights will be brighter, and your engine will be happier since the oil pump will also give more flow of that precious juice which keeps it healthy   8)
