Title: carb spring and crankcase breather ?'s Post by tbalam on 12/31/06 at 18:52:09 i was doing the spacer mod the other day and when i pulled the top of the carb there was the larger, long spring; however there was a white washer and then another smaller length spring. Is there supposed to be 2 springs in the vaccuum slide or only one? I would assume this would change how the slide functions if this was a mod by the previous owner. second question: for those of you that went to the K&N cone filter what did you do for the crankase breather tube? along those lines how much oil should come out of the breather tube witha stock filter? I am losing maybe a few tablespoons on a sixty mile ride, but my filter is very clogged. |

Title: Re: carb spring and crankcase breather ?'s Post by justin_o_guy on 12/31/06 at 19:13:22 Filter is clogged? Air filter clogged with dirt? Losing tablespoons full of oil adds up with a 2 quart sump. I don't remember there being a second spring under the diaphragm when I did thge spacer. exploded view on page 4-1 shows 2 springs. 1 big long dude & then a small one that allows some play in the needle. The white spacer is on top of the needle, the spring is below. I don't remember having it out.When ya pull the plate with the 2 screws on top of the white spacer, note the dimple. That point goes down. It's small,Yea, that's the kind of stuff I remember. |

Title: Re: carb spring and crankcase breather ?'s Post by lancer on 01/01/07 at 06:18:45 The little spring keeps an upward tension on the needle to hold it in place. When the spacer mod is done ... (making the white spacer smaller) ... that little spring can then raise the needle slightly and allow more fuel to flow, which richens the fuel/air mixture in the midrange. |

Title: Re: carb spring and crankcase breather ?'s Post by tbalam on 01/01/07 at 15:08:51 Thanks, the spring i was reffering to was also under the diaphragm and just as big as the large one but shorter, there is a white spacer in between those to springs. i have redone all the stuff that is under the plate, i.e, needle, spring, and little white spacer. so i guess there is three springs under the diaphragm cap- 2 large (one long and one short), and 1 small needle spring. |

Title: Re: carb spring and crankcase breather ?'s Post by Reelthing on 01/01/07 at 15:27:08 spring business seems strange - only a little one on the needle and a single big spring that pushes down the diaphram on US spec bikes - now there has been a few added items on EUR spec bikes noted here in the past - where are you? that may be a power limiter - could make a picture? |

Title: Re: carb spring and crankcase breather ?'s Post by Reelthing on 01/01/07 at 16:12:11 I'm getting the above picture (single spring) on alpha-sports.com for a 96 ls650 - how did you get to the dual spring picture and is that what you have in your carb? |

Title: Re: carb spring and crankcase breather ?'s Post by tbalam on 01/01/07 at 16:13:30 1996, i modded that picture from a similar one. the spring and washer parts I added with paint to show what i have. i have something like my picture in my carb. |

Title: Re: carb spring and crankcase breather ?'s Post by Reelthing on 01/01/07 at 16:20:30 got it - if my memory holds up - some of the EUR models had that spring and spacer to prevent wide open throttle to hold the horsepower down for the initial motorcycle licn - as it is limited to 20 h.p. or some such |

Title: Re: carb spring and crankcase breather ?'s Post by tbalam on 01/01/07 at 16:24:44 ah thanks i'll take it out. by the way where'd you get the iridium plug? |
|
Title: Re: carb spring and crankcase breather ?'s Post by Reelthing on 01/01/07 at 16:28:21 what main jet is in the carb? seems like they came with a 135 or so the IR plug was the only part I ever found the local suzuki to have in stock |

Title: Re: carb spring and crankcase breather ?'s Post by tbalam on 01/01/07 at 17:17:08 i rejetted it to a 150 main. i think it had a 145 when i bought it, though i can't remember for sure. I changed the top screws to allens and in the process looked at the spring it looks like someone cut it and then used the washer to allow it to work as one spring. |

Thanks for posting this. I checked this board as I was reassembling my carb this afternoon. I wasn't sure which way the dimple went. I'm assuming the dimple is to prevent the spacer from causing the needle assembly from sticking in the up position? Ken |
