Title: Help, Stalls off idle, goes dead if idle too long Post by mew7789 on 08/14/05 at 19:13:14 I drilled 4 3/8 " holes in my rear baffle last year. Rode all season with no problems and more power. I havn't ridden much this year due to shoulder surgury. Went out for the first time in 4 months. After 6 miles with bike running great it stumbled and popped once. I was in 5th gear at about 60mph. I slowed to stop for a traffic light and the bike died. I trailered it home. Removed carb and cleaned it. Reduced white spacer to 1/2 while I had it apart. Re assembled. Bike started up. after warm it will die if you quickly blip the throttle. If you roll it on a little slow it will rev on up. I rode it, It is hard to launch without dieing but then runs great until you have to stop. It doesn't die on decel. Just when you gas it to leave the stop. If i pull the choke out 1/2 it will launch fine. Like an accelerator pump failure on an old car carb. I,m wandering about the "transient enrichment valve" on the diagram. Any Ideas would be appreciated. savage is a 95. |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by mew7789 on 08/15/05 at 09:38:02 Thanks guys, I'll check the washer first tognite since I don't have to pull the carb for that. As far as the slide goes, it has some light vertical scuffing. It was on there when I looked down the bore before disassembly. Is there a fuel filter some where? I bought this bike new in 95 and have had zero problems until now. Now thats Value! |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by Reelthing on 08/15/05 at 09:54:27 there's one in the tank - well actually a screen - on the petc0ck - and another large debris blocker in the carb that sits above the float needle seat |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by Digger on 08/15/05 at 22:10:39 Mine did those things when the plug got fouled. Try changing the spark plug before you do anything else. If it works good immediately afterwords, perhaps the idle screw is set too rich. |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by mew7789 on 08/18/05 at 06:05:05 Thanks for all the pointers. I pulled the float bowl and removed the main jet to verify the washer was in place. Replaced it. I removed the pilot jet and cleaned it. I had just sprayed it while installed before. While these jets were out I gave each oriface a shot of card cleaner. Put it all back to gether and it fired right up. The problem is 80%better. Rode it down the road and it has like one little hickup if you instantly go full throttle from stop. I was not preprared for the difference that White spacer made in power. Amazing! I think I'll change the plug just to be safe. Thanks again. |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by rkutzner on 08/19/05 at 04:55:31 Wow, 4 3/8s holes? I have my spacer down to closesr to 1/4 of original size (thickness of 2 #4 washers), idle mixture screw out to 2.5 (may need to go up in pilot before winter) and main at 152.5. This is with only a K&N and 2 1/4" holes in the rear muffler baffle. This combo is giving me perfect power with no hiccups and nice plug color. Because of your 'hiccup', I'm wondering if you are still a little lean on the bottom end with that many baffle holes. Maybe going up one size in pilot is in order. What is your idle mixture screw set at? If out more than 3 turns, conventional wisdom says go to the next size up pilot jet. Just something to think about.....so exactly where did you put the 4 holes? With the rivets and welds, I could only find 2 spots to drill. Can you post a closeup pic? |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by mew7789 on 08/23/05 at 19:45:59 http://www.bikepics.com/pictures/414694/ Above is an Image of the Muffler On Bikepics. I let the bike set a day or two and it is worse now. It will start and run for about 60 seconds and quit. Took the carb back off and dissasembled to check. Find nothing out of place. Have checked header for leaks and even temp plugged holes in muffler but no difference. Does anybody have a source for rebuild kits for the mikuni. I have removed the gas and replaced it as well. If you start it and hold half throttle it will run a bit longer but will eventually die with a load backfire. This thing failed running down the road, I can't help but think something is damaged. Edited by Susan to fix picture link. Note to mew7789 -- the pic is so dark, I couldn't really see anything... |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by timk on 09/10/05 at 09:57:22 Mine was doing the same thing. Turned out to be a dirty slide/bore. After getting warm the symptoms would appear. I really don't care for the CV carbs, so I purchased a 38mm Mikuni. Haven't installed it yet. |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by slavy on 09/11/05 at 09:56:15 Check the rubber O-ring between the brass fuel valve and the aluminum carburetor body. The EPA gas kills all the rubber components and this O-ring starts to leak and floods the carb. |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by mew7789 on 09/14/05 at 07:12:01 The O ring looks great. I have a feeling the idle mixture screw is not seating. From the photos posted on this site it looks like it is a lot farther down the hole than what I'm seeing on mine. If I'm not seating it then I am counting turns from the wrong place. Could Too rich cause this? Also, another post here recommends running some 2stroke oil in the gas to keep the slide lubed. Anybody doin that and how much. Thanks. |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by mew7789 on 09/24/05 at 16:04:21 Bought a stock carb for a song off ebay and installed it today. Same thing, I'm gonna pull my hair out. It will idle for maby 1 minute and start missing. If you hit the throttle it dies immediately. If you wait a minute and restart,take it to half throttle, it will run for like 3 minutes missing now and then and then die again. |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by torque on 09/24/05 at 17:25:02 are the jets in the new carb stock? is there black smoke puffs coming out the end of the muffler? sounds like its rich to me,check for any air leaks around the carb too |

Title: Re: Help, Stalls off idle, goes dead if idle too l Post by mew7789 on 09/27/05 at 16:46:54 Gotcha, No oil. I got to thinking about it and decided to change the plug again. With all the mess I went through with the old carb I thought it might have fouled it out. after changing the plug with the new carb installed it ran great. Took about a 10 mile ride and it ran smooth as silk. This carb must have been tweaked a little because it has no idle screw cover. Anyway, no backfires with a very open exaust (see above). Thanks to all who have contributed to this post. I really appreciate it. ;D |
