Title: Bike wont start! ARGH! Please HELP Post by Weez on 08/13/05 at 10:42:51 Man I just got my licence and i'm rip roaring to go, so I get it started, it goes fine and i'm just warming it up with the throttle, and then I let off the throttle to pick up something and it dies. So I try to start it again with no luck...I keep trying until I run the battery down, I charge it up and then try more, no go, even get someone to hold the choke out while I try to start it, no go. Then I think to myself, maybe its the gas. Come to look I was low on gas so I go out and get some, fill it up (this is the next day by now) and it still is a no go! Just goes wricka-wricka-wricka-wricka...never starts up. I don't know what to do, it was working fine before. let me know what ya'll think... weez |

Title: Re: Bike wont start! ARGH! Please HELP Post by Reelthing on 08/13/05 at 11:14:39 did you move the fuel lever to PRI and give it a go? |

Title: Re: Bike wont start! ARGH! Please HELP Post by torque on 08/13/05 at 13:05:15 hey , did you check the spark plug,and the decompression cable,to see if it is adjusted correctly? i would try a new plug. Good Luck! |

Title: Re: Bike wont start! ARGH! Please HELP Post by Weez on 08/13/05 at 15:01:12 Hey. Yah the full shutoff valve is in the PRI position, but I was just looking in my manual and it says "Is the fuel shutoff valve in the ON position..." Maybe I need to try that. Also, I'm not sure about the sprk plug, how do I access it? Also, hw do i know if the decompression cable is properly adjusted thanks Weez |

Title: Re: Bike wont start! ARGH! Please HELP Post by torque on 08/13/05 at 15:42:16 if your not sure about the spark plug,i would change it just to be sure. you will have to take the tank off,and the chrome cover on the left side of the head of the engine (left side when sitting on it).When taking the tank off youll have to remove the seat and the two bolts at the bottom of the tank,then remove the fuel line,vacum line from the petc-ock.Then slide the tank backwards and liftup, when it comes loose disconnect the wire connector and unscrew the speedometer cable. then remove that chrome cover then the plug. The decompression cable nut shold be about right in the middle.But when u can see it try to start the bike just to see if it moves. GOOD LUCK |

Title: Re: Bike wont start! ARGH! Please HELP Post by methom on 08/13/05 at 17:23:48 I had something similar with my 2000 after it had been sitting for a long time. Are you sure that your battery is fresh and charged? I swapped in a new battery and it fired right up. |

Title: Re: Bike wont start! ARGH! Please HELP Post by Weez on 08/13/05 at 18:19:47 yah battery is running fine, all charged up, I'm thinking it is the sprk plug...I wish it wasnt such a hassle to cheack it, on many bikes its not as complicated, I mean removing the seat and tank and all...a little intense but i'll deal with it, hopefully be fixing it tommorow |

Title: Re: Bike wont start! ARGH! Please HELP Post by WD on 08/13/05 at 19:28:33 Toss the little chrome piece in the trash and no more fighting to change the plug. Last time I changed mine, the NEW reinforced fuel line split. >:( -WD |

The reason I asked about PRI (prime) is you said it was low on fuel - the pri will bypass the vac diaphram and fill the carb bowl - could be the plug I guess but seems unlikely to instantly fail when you let it idle - could washed out what with somebody holding the choke out - the choke should stay out by itself what year is the bike? |

Title: Re: Bike wont start! ARGH! Please HELP Post by mikedasavage on 08/13/05 at 21:51:34 i've found pri to be a bad thing everytime for me. If your bike has been sitting in pri for a while i bet your spark plug is soaked leave your bike in On and change your plug its really not that bad to change the plug. if you have two people its a million times easier. The seat takes two screws to remove. then the tank is held in by two bolts be carefull with fuel lines when removing. but anyway if you have a second person they can hold on the side using part of the bike frame to hold it while you change the plug i actually managed to do it by myself ussing my knee to hold the tank in place against the frame and changed out the plug. then later i had to do the carb and my b-in-law held the tank while i adjusted the needle. |

Title: Re: Bike wont start! ARGH! Please HELP Post by Reelthing on 08/13/05 at 22:05:41 Oh I certainly agree the PRI can be bad - only use it if you know the carb is empty of gas - say ran it out or had it off to change the jet, or the vac petc0ck is not functioning correctly - sounds like the thought here was he ran it out. |
|
Title: Re: Bike wont start! ARGH! Please HELP Post by mikedasavage on 08/13/05 at 22:12:26 yea i agree with you. but in one of his posts he said yah it was in prime which leads me to believe he had it there the whole time even after add gas and charging the battery which would be bad ;D |

Title: Re: Bike wont start! ARGH! Please HELP Post by dannimal on 08/14/05 at 02:06:27 I changed the plug a month or two ago (to do normal maintenance) And I'm not sure how I got away with it (small hands maybe??) I didn't really have to take the tank off. I did loosen it and slide it back but never took it off. It took more time to put the clips back on the carb hoses than it did to change the plug or re bolt everything back together. If I can do it alone, You and your friend helping you (the one that held the choke?) should have no big problems and get it done in under an hour tops. ;) |

Title: Re: Bike wont start! ARGH! Please HELP Post by Weez on 08/14/05 at 07:19:14 Well this is great, all these replies, and I think I know what my problem is, I made a big mistake. I have been running the bike on "PRI"...I thought this meant "primary tank" - as appose to reserve. "in one of his posts he said yah it was in prime which leads me to believe he had it there the whole time even after add gas and charging the battery which would be bad" This is exactly what i've been doing...crap...well I guess i'll change the spark plug, but have a I messed anything else up? And, why is there a "PRI" option, it seems a reserve and regular would be all you need...when are you suppose to use it? My bike is a 1986, I hope I havent ruined anything more than the sprk plug...

Title: Re: Bike wont start! ARGH! Please HELP Post by gazab44 on 08/14/05 at 08:57:30 The "on" and "res" allow fuel into the carb via the vacuum operated diapham in the petc0ck. In "pri" the fuel bypasses the diaphram (on all time). I use "pri" if I have drained the float bowl or suspect other fuel delivery probs. Leaving in prime would not have any adverse effects because the carb is a venturi action( somebody correct me if i'm wrong) |

Title: Re: Bike wont start! ARGH! Please HELP Post by Reelthing on 08/14/05 at 09:01:52 you use the pri to fill the carb up after it's been drained or you have run out of gas - you see on and res are both controled by vac and will not let any gas flow unless the engine is running - if the petc0ck is working correct- which leads to danger of running in pri - if the float doesn't shut the gas off you can have fuel leaking all over the place and into the engine - like a failed petc0ck and do - the thing to check is the oil - look in sight glass do have the normal amount or is it over full? if it's over you need to change the oil like now. |

Title: Re: Bike wont start! ARGH! Please HELP Post by torque on 08/14/05 at 09:10:01 i dont beleive you hurt anything mechanically,running on prime (pri) lets gas flow into the engine even when the bike is not running be cause there is no vacum,u use prime to start the bike after u completely run out of gas,(on,and,reserve) it fills the caburetor with gas,also use it when u do any carb mods that require draining the gas from the carb. when u take the plug out spin the engine over gas should come out fixing your problem. the spark plug might not be damaged, but if u take everything apart u should change it ,instead of putting it all back together and still wont fire. |

Title: Re: Bike wont start! ARGH! Please HELP Post by Weez on 08/14/05 at 10:31:29 hey all, thanks for all the great advice and help...I spent about an hour today with my good friend working on it. We took out the spark plug and tested it for fire (grounded it and watched for a spark)...when nothing happened we realized that was probably the problem. The spark plug was still in good shape, so my mechanicaly inclined friend cleaned it with a rag, his finger nail, a knife and other various pointy objects. WE then tested for fire again, and presto! Good to go, so we put it back together and she runs wonderfully. Then of course as I am ready to go for my first ride it starts raining...blah..oh well, i'll go later tonight. So! It works now, the spark plug was the issue...and P.S. it is a b*tch to change! man, its brutal. I like the door idea but was hesitant to do it right now...maybe later...anyways, moving on to the next issue- the end caps of my handlebars keep falling out. i'm just going to put a pop-rivit in them.

Title: Re: Bike wont start! ARGH! Please HELP Post by mikedasavage on 08/14/05 at 18:35:51 i think you exagerate Weez ;D Its not so bad. Like i said i did it just lifting it and moving it to the side while using my knee and the bike fram to hold the gas tank up i changed the plug 8) it only took like ten minutes |
|
Title: Re: Bike wont start! ARGH! Please HELP Post by CHRIS on 08/14/05 at 18:41:14 Only problem I've ever seen with leaving it on prime other than the plug drowning is if the needle sticks open it will fill the crankcase and airbox (seen this possible bomb waiting to explode on a 4 wheeler that came in to the shop, said the battery was dead, it was actually gas-locked, gas everwhere!) |
