Check the bottom wire on the TWO PLUG of your CDI with either a VOLT METER or a 12V light TESTER and see if you get a reading on the VOLT METER or the LIGHT TESTER LIGHTS UP. Alleyoop And it should be what? 40-80 VAC.?only while cranking the motor right?Also, in my harness, the bottom two on the 4 wire plug have green wires from them and only one is connected to a ground. Should I splice the other into it? |

THREE 3/4" HOLES???!! isn't that almost like removing the whole back cover of the exhaust? Or do you mean 1/4 or 3/8 holes?if you add them all up along with the stock outlet, you have a 3" exhaust  |

I bought a pair of Michelin City grip tires. I love em  There is no comparison to the factory chinese ones. Best policy is to NEVER skimp on tires and brakes. They are the MOST important part!  |

[replyingto=jeepsteve92xj]jeepsteve92xj[/replyingto]I wonder of one could further improve on the new type fan by cutting a few small air inlet slits in the shroud in various places |

[replyingto=tvnacman]tvnacman[/replyingto]Yeah Thanks  I definitely have an ac. systemThe original cdi was restricted. But getthis; The 2nd wire on the two prong connector(the one thats supposed to go to a kill switch) went down to a pickup sensor on the clutch bell. I disconnected it, and it revved like crazy. I bought a new 139qmb, and built it up BBK,cam,variator,gears,carb... I was not happy with it, so for now, I put the original motor back in. Heres where the problem started. No spark, so I tried an orange cdi. no good, I put in a used cdi, and it ran but rev limited.I put in a non rev limited cdi, It started and revved. when I went to ty wrap it to the frame and button up the plastics, no more spark. Is it possible that the wires from the stator were wrong? (firing or trigger ckt on power in ckt, and power in AC volts on trigger pin? would it start and run and then let go  |
