Title: Rich Mixture Vs. Voiding Warranty? Post by nobrakes on 05/31/11 at 16:05:16 As many of you know, these bikes are way too lean, and I'm worried that it may harm my engine. It comes from the factory this way and if problem should occur, would they consider it a factory defect? My guess is probably not. So, I would really like to hear others who have worried about this as an issue. I'm kinda hell bent on making an adjustment, since the plug is whitish, but also wondering if i should wait it out another nine months? |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by thumperclone on 05/31/11 at 17:10:50 how many miles is your warranty?? fix the lean condition and ride warranty will be over in a snap... |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by Routy on 05/31/11 at 19:21:02 Does it run good ? I'd bet it does. It's under warranty, ride it ! If its not running good, its a warranty issue, let the shop deal w/ it. When its outta warranty, start hackin,.....if thats what make you feel good. |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by nobrakes on 05/31/11 at 20:00:08 Thanks for the input guys. Well, the plug is white. It runs good until I push the rpms a bit, then it takes a little time for the gas to catch up( I guess). I've had other single block bikes; that loved being pushed; that was in the early 80's. |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by verslagen1 on 05/31/11 at 20:02:04 We all do our own thing by the seat of our pants. Most of us own it out right w/no warranty. A few actually take to a dyno and find out how good or bad it is. |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by Gyrobob on 05/31/11 at 20:24:06 That begs a question. What is a typical number for rear wheel horsepower for a late model, stock, S40? Does a stock LS650 have any more or less horsepower than a stock S40? And, to stay within the thread, how much HP gain can we expect from richening the mixture to something more stoichiometrically correct? Can we achieve 14.7 to 1 (the elusive lambda ratio),.. or am I dreaming? White plugs indicate something more like 18 or 20 to 1, eh? No wonder richer jets are discussed a lot here! Just wondering,... |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by nobrakes on 05/31/11 at 20:28:09 To my understanding, it's the same engine, save that the jets were larger back then. |

Yep, they ran richer back then, but all engines run leaner now, not just these bikes. Funny thing is, while running leaner, all engines now last longer than ever before. And many put out more hp too. |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by nobrakes on 06/01/11 at 04:20:57 yeah, but I've noticed you have the spacer mod. |

Only because it "needed it". I had a perfect idle, (brass plug never removed) it run perfect from 60 on up, (145 main jet) but had an irratic surging motion in the low to midrange. One click on the choke would smooth it right out. The spacer mod couldn't have fixed it better. My advice has always been, fix what needs fixin, not just because you read or heard it somewhere. I do know of 3 bikes (friends) that run fine as stockers. Mine is the only one out of the 3 that had a ragged midrange. And if it "needs fixin" while under warranty, I personally would make the shop do it. They may be forced to keep it feds legal, but they are also forced to make it run good. |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by Routy on 06/01/11 at 07:16:09 Oh, On the other side,....I'm an old guy, not often heavy into the throttle much, never climb 8 mile 6% grades on a 100 degree day anymore, but if you do, stepping up on the main jet mite be a good idea ! |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by nobrakes on 06/01/11 at 07:42:43 Thanks. I bought the bike in Feb. and I babied the hell out of it in this breaking in period. now I'm riding in 100 degree weather and it isn't thrilled with me getting heavy on the throttle. |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by nobrakes on 06/01/11 at 07:45:19 ...it acts like it's running out of gas. |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by Routy on 06/01/11 at 09:40:39 For a lean symtom at hi speed or WOT, always try "prime" first. After that you're probably into a lean jet condition. Others here will know better, but I'm not sure a lean main jet would feel the same as running out of fuel. Keep in mind that in a WOT situation, there is minimum manifold vacuum to hold the petcock valve open, so is the reason to always try the prime position before assuming a carb (rejetting) problem. But if it is under warranty, I .....myself, would let the shop handle it. |

Had anymore smoke tickets lately ? ;D |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by nobrakes on 06/01/11 at 12:22:07 Hey, I'll give that prime position a shot! I don't dog it all the time, but it feels good to take off like a rocket once in a while. Also want to see the racing video of you and Bill! |

Title: Re: Rich Mixture Vs. Voiding Warranty? Post by Oldfeller on 06/01/11 at 12:35:48 Yeah, don't hold your breath waiting for Bill to show up at the race spot. ;D ;D ;D ;D Besides, the tick-tick-tick-ticking would plumb drive you crazy while you wuz a waiting for the starter person to drop their arm. Me, I don't think I'd have to worry about Bill's smoke other than at the starting line, well not unless the prevailing wind direction was blowing from up behind us real real real strong like. You see, Bill has a standing invite to show up at Deal's Gap during Dragon week each year and he gets him another opportunity for at least one other run sometimes closer to Labor day a bit later on in the season. This year could be special you know, Verslagen will be there at the end of this month so Bill could show him in person all about his red magic stuff as performed by the hands of a true believer. 8-) |
