Title: Have fuel, have spark ... no start! Post by tixin on 06/22/11 at 13:00:36 I emptied the fuel cup three times and removed spark plug and found it like new, dry, with strong spark ... but the bike won't start. Battery is freshly charged and crank well. What else can I check? I did get a couple vrooms for half a second! Thanks. |

Title: Re: Have fuel, have spark ... no start! Post by jdeluca on 06/22/11 at 13:13:42 About how long are you cranking for? Without checking compression, If you crank for a few seconds I would think the spark plug would get wet; if it's remaining dry I would think that no fuel is getting into the cylinder. If no fuel is getting to the cylinder, however you have drained the carb bowl, then I would think you have some clogged pilot jet passageways. Is the bike new? Or did you just pick it up? When did it last run/run right? Is it all stock or do you know there have been some modifications? Is the Air filter clogged or is it dirty/filled with oil/fuel? A little bit more info might help a little! :) Welcome to the forum! |

Title: Re: Have fuel, have spark ... no start! Post by justin_o_guy2 on 06/22/11 at 13:15:33 How much gas came out when ya drained the bowl? Enough to think its actually filled? Was it clean?You used prime to refill it? How much cranking has been done since the battery was charged? Get that thing in Neutral, so youre not getting any clutch drag in it at all. Prime on the petcock, for sure. Crank with no throttle Start? Laugh & Giggle No start? 1/2 choke, no throttle Start? See above.. No start? Full Choke, no throttle Start? See above No start? Id have to get some Berrymans or something wih a propellant that will make it fire. I dont like Starting Fluid for gas engines, WD40 doesnt work any more, or so Ive heard. Pull air filter out anyway,, even before you go with the spray, pull the filter out, make sure the thing is breathing easy. What happene, anyway? How lon you been riding it? Whats the history,, |

Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/22/11 at 13:33:32 Bike is 2007, and I just picked it up. Seller said it was tuned up last year, but it didn't want to start this year. I got about a cup of gas for the three drains. I cranked about ten times for about 5-10 seconds each. The battery still crank after that, but I recharged anyway, then repeated the process. Smelled gas after cranking excercises. Have not checked air filter, but will do today. I will also follow the starting procedure as suggested and report back. Thanks. |

Title: Re: Have fuel, have spark ... no start! Post by jdeluca on 06/22/11 at 13:41:42 I wonder if the clutch issue is part of this issue...When the engine is cranking, is it a strong crank or does it sound like it is cranking under a little bit of a load, as in the bike is trying to drive while you are cranking...I'd suggest putting it in neutral so at least the transmission isn't trying to push while it's cranking...just my $.02... |

Hint... the carb's got gas, but the engine don't... Pull the carb, and clean the jets and passages, make sure the slide is free... ;)... |

Uh oh... this may be more than I can handle! BTW, JOG, I followed your instruction and got a vroom for about 1 second, and then back to just cranking and cranking! I love scenic routes, but you guys have to ride slow so I can keep up! |

Title: Re: Have fuel, have spark ... no start! Post by justin_o_guy2 on 06/22/11 at 19:55:35 At what point did you get the Vroom? Full choke? |
|
Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/22/11 at 20:25:36 Now that you asked, I noted that the vroom only happens on the first crank of the day. Today, again, it was the first crank with prime, no throttle, no choke as suggested. I tried the other configs and no vroom. |

Title: Re: Have fuel, have spark ... no start! Post by verslagen1 on 06/22/11 at 21:37:47 I suspect, like the others, that it's the carb. full clean Hawaiian style is your best bet. or you can throw a hail mary and fill it with seafoam and let sit overnite. but it's not a sure thing, did work for me but not as good as a full clean. it was wonky for a couple of days, now it's fine. bike sat for a year. fill a oil can with gas and squirt some into the vac port and see what happens after the 1st vroom. |

Title: Re: Have fuel, have spark ... no start! Post by bill67 on 06/23/11 at 04:12:40 If you have the air box off you can get a spray bottle with gas in it and keep spraying in the carb and it will keep running as long as you keep putting gas in it. |
|
Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/23/11 at 09:18:22 Thank you all for your help! I looked through the Hawaiian Style procedure and got intimidated by the time I got to step 16! Is there a "less technical" way other than taking the whole carb apart piece by piece? Does the carb need to be removed in order to fill it with seafoam? How do you fill the carb? From the above replies, I gathered that the vac port is the big round port in the back of the carb, right? What other things need to come out before the airbox can be remove? Thanks. |
|
Title: Re: Have fuel, have spark ... no start! Post by Serowbot on 06/23/11 at 10:24:31 Vac port is right-side, coming from rear of petcock... usually has a chrome spring covering the tube... |
|
Title: Re: Have fuel, have spark ... no start! Post by bill67 on 06/23/11 at 10:32:38 Drop the fuel bowl and put 1 ounce of Sea Foam in it,then put on prime quick way to get Sea Foam in the jets and on the slide. |
|
Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/23/11 at 11:07:57 Vers, I will try to start with some gas in the vac port. Do I need to reconnect the hose before cranking? Bill, do I leave the petcock on prime overnight? Thanks. |

Title: Re: Have fuel, have spark ... no start! Post by jdeluca on 06/23/11 at 12:50:42 Tixin, taking the carb off and taking it apart is really not as bad as it seems, it just takes a little bit of patience! :) Honestly, I think the worst part of it is putting the carb back in place on the bike, that's the part that takes me the most time (about 5 minutes). To drop the bowl, you'll need a phillips head screwdriver, it's 4 screws on the bottom of the carb. They can be tough to get to though, so patience! When removing the bowl, use a little caution as the float is in there as well, you may need to wiggle the bowl a little to get it past the battery box. If you want to try squirting gas in the vac port on the right side of the carb first, then I would reconnect the hose before cranking. Or you could leave the hose off and set the petc0ck to prime. Bill means to set the petc0ck to prime and then crank it, I believe. The seafoam in the bowl won't go anywhere if it's not being forced through the carb. In all honesty, it seems like your best bet would be to pull the carb off and clean it out good; it may seem intimidating, but it's much easier to do than it sounds. :) |

No you just put it on prime when you are ready to start it. |

Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/23/11 at 13:45:42 My plan is to drain the bowl, inject Seafoam via the fuel supply line coming from the petcock, refill the carb by turning to prime for 5 minutes, leave it alone overnight ?? (I don't get this part because it seems the Seafoam would just sit in the bowl?), then crank it in the morning. Please stop me before I do real damage to the bike! If my prayer is not answered, it would be Hawaiian time! |
|
Title: Re: Have fuel, have spark ... no start! Post by bill67 on 06/23/11 at 13:53:50 Seafoam will do nothing just seating in the bowl,You have to crank it some to get it up in the carb.It would be like putting a carb cleaner in a car and not driving it. |
|
Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/23/11 at 17:14:07 Progress Report: Squirted a little gas into the vac port and it vroom vroom right up .... then died as gas ran out. I liked the sound so much, I did it three times. ;D. Injected some Seafoam into the bowl and cranked about 10 times with no result ... yet! Will pull carb tomorrow if it doesn't start tonight! Good night folks! |

Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/23/11 at 22:00:14 I can't sleep .... so I pulled the carb and took it apart! Followed the Hawaiian method and had everything disassembled as shown, except for the needle jet. Is this thing located below the main jet as shown in Step 19?? So far, the only thing I saw plugged up is the pilot jet. Everything else is clean and the rubbers are not sticky. I think I can get by without soaking and just put in new jets. Hope the bike shops around here carry them. BTW, I scratched the valve pretty bad, do I need to replace it now? Thanks. |

It's the valve in Step 19. Had to used a needlenose pliers to yank it out, but didn't tape it first. My bad! |

Title: Re: Have fuel, have spark ... no start! Post by bill67 on 06/24/11 at 04:41:27 Sea Foam or any carb cleaner doesn't workin 10 or 15 minutes it take maybe 8 hours. |
|
Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/24/11 at 06:41:53 Now yout tell me! The carb is in a million pieces now, but looks like only the pilot jet is clogged. Having a hard time finding one locally so I was thinking just soak it in carb cleaner (or better yet seafoam?) for a few hours. Is it even possible to unclog the pilot jet? It is hard to believe that this one little component can bring down the whole bike! |
|
Title: Re: Have fuel, have spark ... no start! Post by jdeluca on 06/24/11 at 06:55:23 Soaking it in CRC should work just fine. Also, if you put the straw on the can, you might be able to blow out whatever is clogging it, just watch your eyes from the spray back! |

Title: Re: Have fuel, have spark ... no start! Post by tixin on 06/24/11 at 20:32:53 Ladies and gentlemen, I would like to announce that my bike has awaken from her deep sleep! This would not be possible without your help and the excellent how-to by SavageWahine. Many thanks! If anyone is hesitant like I was a couple days ago, stop worrying and just do it. I would like to add that taking out the battery box is the first thing I should have done before removing the carb. It was a challenge taking it out, and after wrestling with the darn thing for more than 30 min. trying to put it back, I gave up and remove the box and was done in 5 min.! Ahhh ... the satisfaction of finally hearing the vroom vroom vrooommmm! ;D |
