Title: can't get her started Post by jspace on 06/22/15 at 11:51:06 After about a year in the garage i can't get the bike started. 04' with about 1500 miles on it with a raptor petcock. I stored with the carb bowl empty and siphoned out the gas in the tank. The battery was pretty weak from not being on a trickle charger over the winter so i replaced that. It cranks but thats about it. Before i tear the carb out any suggestions to try? I did open the drain plug on the carb and the gas that came out looked fine nothing gunky. Any advice would be helpful. |

Title: Re: can't get her started Post by Dave on 06/22/15 at 12:05:23 Pull the cap off the carb where you plugged the vacuum port, and then find a way to squirt a bit small amount of gasoline into the port (teaspoonful). Then replace the cap and see if the bike fires up for a second or two on that small amount of fuel. If it does....then you know it is a carb/fuel related issue that is keeping the bike from starting (not a compression or spark issue). |

Title: Re: can't get her started Post by jspace on 06/22/15 at 12:20:49 i poured some gas down the plugged vacuum tube and it did run for a few seconds. does that mean i need to pull the carb out and take it apart? |

Title: Re: can't get her started Post by Dave on 06/22/15 at 12:23:43 That tells you that no fuel is getting to the engine through the carb. So the fuel tank, petcock, fuel line or carb could be causing you a problem. Generally the problem in storage is the pilot jet or main jet gets gummed up and will not flow any fuel. Since you said that fuel will flow out the float bowl drain....I would say you need to drop the float bowl and clean the main and pilot jet as a minimum. On something like that I would most likely take the entire carb off for a cleaning and thorough "look through". |

Title: Re: can't get her started Post by justin_o_guy2 on 06/22/15 at 12:46:52 If you don't get the right tool, you'll wreck the bolts. A number two Phillips ain't it and if they have never been removed, you'll probably be ahead getting it on the bench. Penetrating oil, 50/50 acetone and transmission fluid, do that first, give it time, do it again.. Patience to avoid a problem is better than fixing it. Ha! JIS, remember ed it, I have used the bench grinder to flatten the tip of the Philips till it seated deep enough to fill the X. |

Title: Re: can't get her started Post by jspace on 06/22/15 at 15:01:10 I pulled the carb out and took it apart. A little dirty but nothing real bad. I took both main and pilot jet out and i could see they weren't clogged. I can see through the hole for the main jet into the top of carb. Should i be able to see light from the top of carb through the slot for the pilot jet? |

Title: Re: can't get her started Post by gizzo on 06/22/15 at 18:03:36 That's good that the main isn't blocked. But, the bike doesn't start and idle on the main, so the idle and cold start circuits could still be gunked up. The best thing I've ever come across for cleaning carbs is Yamalube Carb Dip. I think it's meant for ultrasonic cleaners but works really well just for soaking the carb in. It's a bit $$$ but you can store it and reuse over again many times. You soak the carb (overnight works well) then rinse it in water and blow dry the passages with compressed air. A piece of soft wire (fuse wire is nice) is a good tool for poking around to loosen blockages. FWIW when I lay up my bike I drain the bowl then run it til it's dry. I don't have any problems starting up even a year later. My 2c and YMMV etc. |

Barely. I just grabbed an old pilot jet, and I was able to to see a pinhole of lite, but only after try different angles (and different eyes). You should be able to poke a thin strand of copper wire through it. |

No....the Pilot circuit snakes through the carb, goes through the idle mixture screw passage, and eventually comes out in the holes at the top of the carb throat on the engine side of the butterfly. The hole in the Pilot Jet is very small......but you should be able to see some light through it. |

Title: Re: can't get her started Post by justin_o_guy2 on 06/23/15 at 07:47:07 While its apart, get Berrymans spray, use the red tube, WEAR eye protection, keep it off your skin, ventilation or outside, its some serious stuff, You can drop jets in a shot glass and squirt some in, let them soak, use red tube to blast through the idle circuit., etc, but, some WILL blow back, I dont like it on me, it kinda burns, Use antiseize on bolts. They wont fall out. But they wont Become One with the carb. You sure popped it apart quick.. Most folks fight hard. Clean dry slide, no oil, no fingerprints, protect rubber parts from cleaner. |

Title: Re: can't get her started Post by jspace on 06/23/15 at 19:19:48 i cleaned every bit of it i could with berrymans carb cleaner. i did not take the float off because i couldn't get that pin out thats holding it in place. Put everything back together and still nothing! I think i'm going to try soaking it overnight in some carb dip. Not quite sure what to try next if that doesn't work. The float looked ok and the float valve moved easily. |

Title: Re: can't get her started Post by Art Webb on 06/23/15 at 20:00:05 if you're going to dip it you had best get that float off and get the needle and seat out, or the dip will ruin them no plastic and no rubber can go in the dip, only metal |

the yamadip is safe for rubber and plastic. |

Title: Re: can't get her started Post by Art Webb on 06/23/15 at 20:42:06 I am shocked something that actually works won't harm that stuff learned another new thing |

Title: Re: can't get her started Post by jspace on 07/25/15 at 12:13:54 Finally got the carb stripped all the way down. Tested the float in boiling water and it looked fine no bubbles. The float valve looks ok as well. I'm getting ready to dip the carb. Hope this finally works. |

Title: Re: can't get her started Post by jspace on 07/26/15 at 12:52:52 after becoming very intimate with the carb stripping it to nothing i must say the carb dip worked. Put it all back together and she fired right up. Thanks for all the help. |

Title: Re: can't get her started Post by jspace on 07/26/15 at 13:00:24 I did manage to lose the washer behind that clip (#25 pg 189 of clymers). Does anyone happen to know the dimensions of that washer especially the thickness and if it was metal or plastic? |
