Title: 5th gear bogging down and sputtering and dying Post by mattnovy82 on 07/29/11 at 20:59:12 hey guys i have a 98 savage and an open exhaust basically a big hollow chamber off a yamaha welded on to the head pipe and the old feller mod air filter with cover removed and snorkel removed also half white spacer mod and when i have the bike opened up in 5th gear it spits sputters and eventually dies what is causing this my air mix screw is about 2 3/4 turns out i havent rejetted yet am i getting to much air or not enough fuel or is it something different? also what is the little cable under the valve cover for and does it need to be adjusted a certain way? thanks in advance |

Look for a vacuum leak. The idle mix screw adjustment is never the problem at hi speed running. The cable is probably the comrpession release?? :-? |

You have all these mods and you haven't rejetted? I'm surprised it runs long enough to get it 5th gear. The 1st 4 bullets will make it run incredibly bad on stock jetting. start here... http://suzukisavage.com/cgi-bin/YaBB.pl?num=1309246277 |

Or at least I've never known a lean main jet to cause an engine to "die". I'd suggest you find that problem first,.....before modding the carb. |

They are really cheap, 2 - 3 bucks apiece. Just ask for a range of jets to try for a mikuni carb. Have you tried reducing the amount of air coming into the motor? Do you know what size jets you are running now? |

Title: Re: 5th gear bogging down and sputtering and dying Post by spacepirates on 08/01/11 at 10:35:48 Gotta check that you have three things: air, fuel, and spark. the last one isn't really an issue, at WOT the other two are more likely to be at fault. so, check that at WOT your bike is getting just the right amount of both. Check that you have adequate fuel flow from gas tank to carb and carb to engine (petcock to prime and jetting). There is also the chance that your air filter is all nasty and gummed up, so take it out and clean it (blow air throw it backwards). hm, all that being said, make sure it is actually a WOT thing and not a gear things. open the throttle up all the way in any/every gear and see if the same stuff happens. if it does, then it is a fuel/air issue. if it doesn't.... :-? |

Title: Re: 5th gear bogging down and sputtering and dying Post by spacepirates on 08/01/11 at 10:37:50 forgot to add: check your spark plug. pull the plug and look at it. the color will tell you which way you need to jet, based on where in the throttle the bike last was (over the past few minutes) before you shut it off. white = too lean, dark/black = too rich. you'd have to ride it for a good bit of time at WoT though, and with it bogging down it wouldn't be fun... |
