So I'm having a problem.
I pulled up to a red light yesterday on the 2000 Cyclone and put the bike in neutral. About 10 seconds after that the bike just "turned off". It felt like an electrical turn off...no stuttering or sputtering, just off.
So, I hit the ignition and the bike turned right back on. I proceeded home.
As I was rounding a bend to get on to my street (without the throttle turned) the bike "turned off again". Same as last time, no stuttering at all, just off.
I get it home, take a look at all the wires and nothing. No cuts.
I let my friend drive it to the store about 3 hours after this and he says nothing happened, bike ran great and didn't stall.
About 2 hours after that we are leaving and I hop on the bike, starts right up, I go to leave the garage and it shuts off again. This time though, it won't start back up, and it sounds like a fuel problem. I can gas it to start it but any time I let it idle it just shuts off.
So I decide to take off the carb. In doing so I have to let the fuel get burned up that's in the float bowl. I turn the bike on and it idles fine until it shuts off due to no fuel.
I take the carb off, see some yellow dust in the float bowl (probably from the recent sand and paint job) but that's it. Not blockages. I put it all back together and now the bike won't idle at all. I checked the mixture screw and it was tampered with (metal plug was gone) so I reset it to two turns out from all the way in.
Now I'm at a loss...should I take the carb apart and inspect everything?? Does it even sound like a carb issue?? How difficult is it to take the carb apart so that you can rule it out???
Thanks for the help guys! |

The shutting off at idle could be the idle mixture screw is set too lean. Setting it to two turns out is a good start. Try 2 1/2 and vary it a little bit each way from there to see what affect that has on not only idle quality but throtle response.
Also check that the tank vent hose is not blocked and the tank vent valve in the fitting that the vent hose connects to does not stick shut. If the tank does not vent properly, there could be a fuel starve condition that shows as stalling or seemingly running out of gas.
The yellow dust is most likely impurities in the fuel that settles out as residue. You probably should clean the carb, take the jets out, clean them and find out what number they are. A 45 slow jet is usually OK for most locales. |

Figured it out.
After taking the carb apart and cleaning it out with about a big can of carb, the bike ran great. Better than it ever had.
After a little 5 minute run I was letting it idle in the garage and it just shut off again.
One of the guys over on the Buelletin Board suggested it was the Ignition Pickup.
This makes total sense. The bike doesn't bog out or stutter when it shuts off, it just turns off, electrically. A bad ignition pickup would definitely cause this, especially because when they go bad they become temperature sensitive.
I took the points cover off and this is what I saw:
Bad ignition pick up. Damn it. I should have known it wasn't the carb.
Nonetheless, cleaning out the carb has definitely made a huge impact on the bike. I have the idle mixture screw 2 1/2 turns out as was suggested by some forum members and it's definitely clean.
Only problem is that pickup is on backorder everywhere, except one place...and I hope I got it.
I'll update when it comes in if it's the problem. |

Only 1 timing plate stud in your pic.Did you remove it or was it missing? |

LoL. I removed it, then remembered that I forgot to take a picture of the damn thing. That caramel glue was all over it too.
I guess that sticky insulation just goes bad or something...not too sure why it eventually melted like that. |

Excessive current/resistance and engine temp would have melted it.
Almost like it wanted you to know what was wrong. |

So, is there an underlying issue as to why it eventually failed? Should I look deeper into WHY it failed as opposed to what ultimately failed?? |

Running lean on an already hot running motor would not help but I would be checking the wiring for resistance just to be sure. |

Well,
I'm close to positive I'm not running lean.
Do I check resistance with the sensor installed or cut off. Right now, I have the sensor cut, waiting for the new one to come in...and what a pain in the ass that has been.
I suppose I'd check across the black and red wires and the black and green wires.
The only thing in the manual about checking the ignition pick up is the hot and cold test with freon and a hair dryer....I thought there would have been another way.... |

Probably not lean now that you have sorted out your muck in the carby but possible before yes? |

Ya, you know what, I guess that is possible. I never thought of it that way.
I'm hoping to get the part today (I may turn into the hulk if I don't). I'll update with the progress.
Thanks for the help. |
