Title: starting fluid Post by savagetyler650 on 01/18/15 at 14:39:58 Ive been having trouble starting my bike on the first couple cranks lately and has been getting me kind of sketched out because i dont want to get stuck somewhere far from home. But i have a k&N air filter and drag pipe jetted the carb and did the idle mixture screw. She only seems to turn on when i add some starting fluid in the air filter. what could this possibly mean? To lean? Not enough gas in the engine? Is my carb tuned right? |

What the heck does that mean? 3 compression cycles? 3 presses of the starter button for 30 seconds each? 3 to 6 comp cycles would be normal. 1 or 2 would be great. |

Title: Re: starting fluid Post by Serowbot on 01/18/15 at 15:09:25 No idea how you're jetted, but it clearly ain't right... What's your "drag" pipe... open?, baffled?... glass packed?... K/n cone?, direct replacement?... What jets do have in there?... Elevation, location?... You're giving s nothing to go on... :-/... |

Title: Re: starting fluid Post by justin_o_guy2 on 01/18/15 at 16:22:33 After the mods,did it ever start right? Can you remember DOING anything, even buying gas, just before it started being a bummer? Has it been going on for long enough to need fresh gas.... Type out some details. |

Title: Re: starting fluid Post by savagetyler650 on 01/18/15 at 18:35:02 Sorry for the lack of info guys im still new to the forum.. I have 2003 savage which i completely changed the air box to a cone filter, 52 (stock ) pilot jet and a 152.5 main jet with a drag pipe that has a mild baffle.. ( from blue collar bobbers) Miami Florida is my location pretty much sea level down here. I try not to crank the motor for more than 2-3 full cycles each time. Its gotten to the point where it takes awhile to start her up. The bike ran fine before the mods had no problems with gas or any electrical |

Title: Re: starting fluid Post by justin_o_guy2 on 01/18/15 at 18:37:11 So,ran fine Before,, but,you still haven't said exactly WHEN it stopped starting well. If you have not had it running and the battery is low,at all, it will only get worse. If you don't have a volt meter,you'll need one. |

Title: Re: starting fluid Post by savagetyler650 on 01/18/15 at 18:56:33 i would say about a month ago.. and the battery is spanking new about a week old fully charged |

Title: Re: starting fluid Post by justin_o_guy2 on 01/18/15 at 20:54:17 Would someone please peel the details out of this guy? I'm tired of asking. |

Title: Re: starting fluid Post by Serowbot on 01/18/15 at 23:50:48 What JOG wants to know, is,... does this seem like a direct effect of the filter. pipe, and jetting, changes that you made?... If so,... something went too far... Big thumpers make their power with torque, over a wide rpm range... If you give too much flow,... they will lose their wideband advantage... |
|
Title: Re: starting fluid Post by savagetyler650 on 01/19/15 at 05:02:43 well JOG you asked me two questions... when did it start happening and how is my battery.. i answered those some what important questions as clearly as i understood them. and yes i feel like it is a direct issue from the filter, pipe, and jetting. but my pipe isnt fully open so the air flow shouldnt be that drastic or could it be that my air filter is breathing to much air in and not enough fuel to start the bike?? because when i ride it seems fine all gears are smooth through out. Im not sure if i should go richer to help it start? Change air filter? Jets? what do you think went to far? |

Title: Re: starting fluid Post by Dave on 01/19/15 at 05:28:32 If you still have the stock vacuum petcock.....give this a try. Before you try starting the bike......turn the petcock to "prime" for about 30 seconds. It could be the fuel in your float bowl is evaporating between rides. |

Title: Re: starting fluid Post by justin_o_guy2 on 01/19/15 at 06:10:23 As your experience grows and you start knowing the answers,you'll understand the need for the details. I still use the carb gurus abilities here,but,even though I don't remember the answers,I do know the questions they need to have answered in order to help you start into figuring out how to get you rolling. If I seem short it's not because I'm angry,I'm on a Kindle and typing SUX,dude. |

Title: Re: starting fluid Post by savagetyler650 on 01/19/15 at 06:38:11 my friend mentioned that dave because it would happen to his atv.. i tryed what you said but it still didnt turn on.. what could i do to not have the gas evaporate? or is that just mother nature at its finest? i understand jog that details are important to figure out my problem guess i could be a little more clear on the issues with my bike.. where could i locate the carb guru section?? i appreciate your effort on trying to help me get her started jog. |

Normally the fuel doesn't evaporate quickly....it takes a fairly long while to evaporate enough to cause starting problems. If you ride one a week you will never notice....once a month and maybe you need to use the PRIME setting. There is a really small brass tube at the front of the carb body, inside the float bowl. I believe that tube provides the extra fuel needed when you pull the enrichment knob....I wonder if that tube and the tiny holes in it are plugged up in your carb? |

Title: Re: starting fluid Post by justin_o_guy2 on 01/19/15 at 07:49:59 I've been caught by old gas and even a little low on gas. Don't twist on the gas, try the choke, both settings. The starter motor isn't gonna melt if you have to hold the button for 5 seconds. If you don't have a volt meter,you'll need one,and at least a small charger. Not good for small batteries to go cramming too many amps in them too fast. Wanna know if the gas has evaporated? Poke a cup under the carb and open the drain. You'll see what the gas has IN it, what it's looking like And how much is in the carb. You can also put a few drops on a rag and see how it lights. Provided you have a good place to start a fire, of course. I am leaning towards it being a tuning issue , but, we've Seen so many petcock issues that it's really time to look at yours, Hey,you smart guys,,, Do the intake and exhaust changes lower engine vacuum? Hope that's not a dumb question,, and don't even try to tell me that there IS no dumb question,,, I've been asked some real good ones and asked some... ohhh,Boy, |

Not at a closed throttle setting for starting the bike. There is so little air moving through the engine that it doesn't know what kind of filter is on the bike. The throttle butterfly is almost completely closed, the slide is all the way down....and the motor is cranking over really slowly compared to idle speed. Air filter and exhaust changes can make a big difference at running speeds, and the stock vacuum petcock can stop functioning at highway speeds when you have a free flowing filter on the bike. Some folks have experienced their bike shutting off at higher speeds - but then it runs fine at lower throttle settings where the intake vacuum is higher. |
