Hey all, been a few years... I was trying to find an answer over at scootdawg lol
I have a wildfire 50cc, and did an engine swap to a 150cc oh, about 5 years ago. It ran fine, except the headlights would get so hot, they'd start to melt the lenses and then burn out. I bought a motorcycle and forgot about it.
Fixin to dig it out of storage and fix it for the youngin, lol
I'm guessing this is a stator problem. Not sure if I should put in a 6 coil stator, or if perhaps I need an 8 coil, AC stator?
I dont wanna wire the headlights to the battery.
Any ideas?

my guess is that you have AC headlights (my 50cc did)
it's likely that the 150 produces more AC output that the original 50 cc engine did.
solution:
get 12v headlights and run them from the battery, or purchase AC headlights made for your 150

Alot faster than the 50cc... I had tried an 80cc big bore kit installed by a shop in the beginning, but it kept going through alot of oil.. so I just ordered a 150 and welded new mounts. I'll get my gps on it sometime and see if I can get an accurate speed. |

I've been told that if the the headlight glows as soon as you turn on the key, its a DC system.
If it doesn't light up until the engine is running, you have an AC system.

I looked into this rectifier thing at one point, thinking maybe there was a resistor or something I could install. Not sure if there is one on the 50cc scooter's wiring system. I'll hafta look into that. Thanks! |

I'll hafta look into that. Thanks! Regulator/rectifier is just what it says, it regulates the ac voltage fron stator down to around 14-16vac, then rectifies it into DC power. Regular incandescent bulbs can use either AC or DC power, as long as the voltage is close. To much voltage and the element heats up to much and blows. The r/r is what keeps this from happening, also keeps from frying your battery by applying dc voltage to it instead of ac... |
