Title: 155 main jet, no start Post by zer0sk8ordie on 10/14/12 at 13:39:09 I got my lancer jet set, changed the main jet to a 155 and I took the spacer out on the slide needle. The bike started for about 5 seconds really rough, then died. Now it won't start at all. I messed with the mix screw but still nothing. Only mods done are k&n cone filter, and I drilled holes in my baffle. Any help or tips would be great. Thanks |

Title: Re: 155 main jet, no start Post by verslagen1 on 10/14/12 at 15:25:58 Did it run before the mod? then put it back and check it. maybe you screwed something up. Next do one mod at a time. start with the jet. since you put in a 155, you musta started with a 145, try a 150 first. |

Yes it ran fine. It was completely stock before though. I will try a smaller main jet. Is it possible to screw that small plate thing in wrong when taking the spacer out on the slide neede? |

Well I took it apart to paint it and decided to get a cone filter, then reading on here they say to change the jets.. |

If you put it in upside down you don't have the holes you need for air to get over the slide. |

You will have to go back in and check these things, and Versey is right, with minimal mods a 150 should do you fine. |

Title: Re: 155 main jet, no start Post by zer0sk8ordie on 10/14/12 at 18:10:51 Ok I put a 150 main jet and it did have the washer, i added a washer to the slide needle and still get the same. Like it wants to start but just won't. My next question would be the 2 hoses on each side of the carb. Those are just breathers correct? I don't have them connected to anything. |

Title: Re: 155 main jet, no start Post by 07s40scotty on 10/14/12 at 20:19:27 You didn't give alot of info... But this may help. It may seem like a silly thing to say but did you prime the carb by turning the petcock to prime for a few seconds? Is the hose to the back of the petcock on tight & the fuel line on proper like? http://suzukisavage.com/cgi-bin/YaBB.pl?board=tech;action=display;num=1098869040 I'm no moto genious but I've had my carb off 6 times since may- messin with 1 thing or another... the tech section holds the key from the great folks here who know what they're doing :) I'm assumeing you took the carb off the bike since you were working on the bottem & top of the carb & went to a cone filter. KISS comes to mind in this case. Changeing your main jet probably isn't the problem- if thats all you did on the bottem of the carb (It'll run like crap- but it'll run). Your worries are probably on top. Is there a washer under the-clip on the needle? Is the small spring under the washer? Is the dimple down on the disk that holds it all in place & can you see that the two holes are about half covered? Is the diaphram under the top cover in right fitting into the tab before you screw it down? |

Title: Re: 155 main jet, no start Post by MiCTLaN on 10/14/12 at 20:30:47 In the same vein of the 07s40scotty's post.. I just had mine apart to do the spacer mod and realized I had dropped the spring at some point, and after putting the first screw in the disk realized that I had the disk in wrong. Did you clean up the carb with carb cleaner while you had it apart? I understand getting carb cleaner on the main diaphragm and TEV diaphragm will damage them. |

Title: Re: 155 main jet, no start Post by verslagen1 on 10/15/12 at 12:52:39 The solution is simple, if you make a mod and it don't run after... return it to the previous condition to verify you didn't make an unintentional change... left out a spring, misplaced a washer, etc. Note: going from a 145 to a 155 and removing the white spacer is a major change. Always adjust the main jet 1st w/o spacer change. Once you get the top end and the bottom end to where you're happy, then adjust the spacer. |

The two holes should be half covered? I put it so they are totally uncovered. I will pull the carb again and try it how you described. Thanks |

You are absolutely right! I'm such a noob.. I had the needle in upside down. It starts and runs, now I gotta fine tune it |

Title: Re: 155 main jet, no start Post by 07s40scotty on 10/15/12 at 21:11:29 Amen o-guy- its simple if you don't complicate it- keeps the fudge factor at bay. :o What Verslagen is tryin to tell you holds the key... It could be alot of things because you changed alot of things at once. Jumpin that many jet sizes is a BIG risk because you don't know which change caused the problem.. Small steps.... 1 size at a time. 1 Mod at a time, it'll take the guessing out of the equation. If you do it that way, you can always go back to what you had going on before you made the change. Let us know if it gets better, sux when a perfectly good machine won't run :-/ - maybe we can come up with a few more things that could cause your problem |
