i own a 125cc pit bike it is kickstarted not electric so there is not a lot of power sources to tap into?

Question

well except for the 5 wires running from the engine into the cdi box after some trial and error i found out if i used the green wire and yellow wire i can power up a 12vlt lamp wich i am fitting to the bike but the power is controlled by the revs and as i increase the rpms slightly i blow the bulb im not an electrician im more a rough cowboy so what im i doing wrong before i fry myself <<

how will it fry the cdi box if im tapping into the wires before it goes into the box# the guy that said cut the red wire why what will that do??##oh i have nowhere to keep a motorcycle battery so tapping into the bikes own power sounds good to me not that i need it real bad i just like to set myself the odd challenge or two and because i know nothing about it makes me more determind to succeed

Answer 1

CUT THE RED WIRE!!!

Answer 2

A voltage regulator between the staor and bulb will save the light. But the alternator is not designed to run a light. It could rob you of power to spark and/or shorten life of CDI and/or stator. I did the same thing on a 79 Yamaha without a problem

Answer 3

if you look through the pages of Denis kirk you will find a voltage regulator $25 buy it and hook it into the wire that supplies power ground the other to the frame and the third wire goes to the bulb i have done this to 3 different bikes works very well and i have never had a problem with burning things up

Answer 4

Stop whatever it is you are doing right now! Go get a small motorcycle batter and either buy or make a mounting kit for the sub frame if you need a light that bad. You are going to either fry that cdi box or ruin that motor if you persist. Either get a self sustaining light or don't ride in the dark.

Answer 5

check to see if your bike has a rectifier on it(four pin device with fins on).. ON a honda based engine Yellow and white got into a rectifier .. you want to tap into the other two... red and green. That should have 12volts.
You might need some sort of regulator, im not sure

Answer 6

make sure you got 12 volt bulbs your running of the magneto

Answer 7

don't forget to put the peddles and training wheels on as well...
