Title: Jet question Post by gazab44 on 05/23/05 at 03:45:26 Read many times about re-jetting etc, but how do I know what size jet I have in the first place? as my 96 has had 2 previous owners. |

Title: Re: Jet question Post by Reelthing on 05/23/05 at 04:54:47 No way to know with out draining and pulling the 4 srcrews (That i suggest you replace with allen head stainless) - the '02 was stock - had a 145 - the '95 had 147.5 when I got it - and pull the main jet - take it easy on the jet re-install when you start the treads - push to hard and the tube can unseat and bind - then you may need to pull the slide to get back in proper |

Title: Re: Jet question Post by Savage_Rob on 05/23/05 at 06:02:49 That's the gist. You just drain and pull the bottom of the carb and the jet is in the center. Replacing the screws with stainless allen heads is definitely a good idea. It'll make accessing it in the future a snap. I did it for the top side too. A flathead screwdriver will remove the jet and then you read the size stamped into the brass. I dunno about you but I had to use reading glasses. My '98 was stock with a 145 also. |

Title: Re: Jet question Post by Diane on 05/23/05 at 08:26:48 While we are on this topic................ How do you then decided what size jet to replace it with? I bought the Krome Werks muffler from Lancer and would like to cover all the bases before I round up a wrench tutor. |

Title: Re: Jet question Post by Reelthing on 05/23/05 at 09:07:41 I've seen some rule of thumb before that said a higher flow air filter was +1 size , a higher flow exhaust was +1 or +2 jet sizes - so call that about 3 (if you open the air intake a little). Stock these carbs have a 145 main - but they are lean as he77 and from eyeballing the stock '02 it's reasonable with a 150 jet and stock pipe - so if you start there 150 + ( 3 *2.5 ) - I'd say 157.5 or a 155 if you leave the filter/air box alone, would be a good start - then you need check the spark plug - are you going to chop the white spacer down to half and richen the idle mixture as well? |

Title: Re: Jet question Post by gazab44 on 05/23/05 at 09:25:09 Don't know about white spacer yet..i'm going to probably increase jet, if it's not been done and then take it from there... :) |

Title: Re: Jet question Post by Hammy211 on 05/25/05 at 01:12:29 I had some trouble locating the right allen bolts in a hardware store. Am I going to find these at the bike shop or does anyone have a better suggestion? I have no choice but to replace them since I skimped on an impact driver and ended up drilling out the top four. I decided after that the $35 dollars would be well spent for any future problems. |

Title: Re: Jet question Post by Reelthing on 05/25/05 at 03:55:33 At least here the sears hardward store by the house has a very fine selection of metric - these are m5 stainless allen head |

Title: Re: Jet question Post by gazab44 on 05/25/05 at 03:59:20 going to check size of jet tonight at work, when not busy of cause, ;) got no problem changing screws...1000's at work :) |
|
Title: Re: Jet question Post by Savage_Rob on 05/25/05 at 05:26:29 I find Ace Hardware has a good selection of metric bolts where I am. Varied assortments.. including the more expensive chrome. I tend to go with stainless. |

Title: Re: Jet question Post by lancer on 05/25/05 at 06:54:11 Prior to removing the stock carb on my Savage in the search for more performance, I found that by going 1 or 2 sizes larger on the main jet and one size larger on the pilot jet, that this would take care of most bikes with a stock engine and K&N style filter and aftermarket muffler. |

Title: Re: Jet question Post by Savi650 on 05/25/05 at 09:01:11 It would be awsome if someone placed something on "how to replace the Jet" in the tech section. There's a lot of us that would like to know how to do this.. I think. :) |

Title: Re: Jet question Post by vroom1776 on 05/25/05 at 13:17:26 The Savage service manual I have is wrong on the jet sizes. Evidently this is a common problem. I went down to a cylce repair shop looking for jets for my savage. I was looking for a pilot jet size never made. The owner pulled up his microfiche on the savage and said the service manual was wrong. This is froma guy I totally trust, too. Yeah, it was really ahrd to find a mikuni 47.5 pilot! Also, beware, there are several types of pilot jets out there! Bring yours along with you when you go to buy a new one... Has anyone changed the pilot jet size, in addition ot the main, with a new air filter or pipe? ks |

Title: Re: Jet question Post by WD on 05/25/05 at 14:54:54 If all else fails, you can drill out the stock jetting. I'm anxiously waiting for the arrival of a 188ish and 210 main jet pair to try. Might borrow a good drill and step up the pilot jet that way... I borrowed a program at work the other day for carb calibrating, i need at least a 185 main with my current set-up... So much for fuel economy. ::) At least I'll be less likely to burn a hole in the piston or fry an exhaust valve. ill miss the flame out the pipe though... -WD |

Title: Re: Jet question Post by gazab44 on 05/26/05 at 03:58:16 Checked the size of the main jet...it's 130. I'm running a 96, stock everything...so what do you all suggest ? :) |
|
Title: Re: Jet question Post by Reelthing on 05/26/05 at 06:04:05 If you look at the specs here for a 96 - http://suzukisavage.com/cgi-bin/YaBB.pl?board=tech;action=display;num=1098869040 yours is close to a "CA" model that had a #125 but also the pilot, needle, needle jet and such are different When you go for the inspection - I forgot what is called - do they do an emssions check? if so your best bet might be to grab another carb from ebay and swap it and back to the other for the inspection |

Title: Re: Jet question Post by Savage_Rob on 05/26/05 at 06:08:33 130? Wow. I guess the European Savages may be even leaner at stock than those in the the US (except maybe California). Here's a link to J & P Cycles (http://www.jpcycles.com/productgroup.aspx?GID=A989B6DF-970F-46E2-968F-F20D04553D66&search=mikuni%20main%20jet&store=All&page=1) where you can get Mikuni mains for that carb. If you have a local HD dealer, they may have them too. Ask for the large round type. The above post points out a very important possibility though. If you get smog checks, you may want to be able to revert to stock for the inspections. Do you also have a smog canister like the California Savages? |

Title: Re: Jet question Post by lancer on 05/26/05 at 06:22:15 Your stock main jet is a #130? That is downright disgraceful. We definitely need to protest, march, or otherwise stir the pot!! On the practical side, what jets do you want? Main jet...pilot jet... I have: Pilot jets: 15, 20, 25, 27.5, 37.5, 40, 45, 50, 52.5, 55 Main jets: 160, (170), 220, 230, 240, 250, 260, 280, plus a bunch of 300 and 400 series. **The #170 is the standard large round version, the others are the smaller hex version...all are of the same thread size and all will work in the stock carb. **The pilot jets may look a little different from the stock but work just fine. I used all of these types of jets in my stock carb before replacing it with performance units. |

Title: Re: Jet question Post by Reelthing on 05/26/05 at 06:29:55 Lancer what you want for the 55 pilot - it have emulsion holes or not ? |
|
Title: Re: Jet question Post by gazab44 on 05/26/05 at 06:50:11 was thinking of fitting a 150 main jet only to start with, would that be ok just to change the main jet? :) the english inspection is called M.O.T. |
|
Title: Re: Jet question Post by Reelthing on 05/26/05 at 06:57:40 You should be able to tell pretty quick! - also it looks like your needle may have 3 notches on it and set to the 2nd - if so you could move the keeper and richen it up - have you pulled the slide yet? |
|
Title: Re: Jet question Post by Savage_Rob on 05/26/05 at 07:13:49 Something funky is going on here. I just saw what appear to be replies to this thread from Slavy and Lancer in two different posts. I saw some similar weirdness yesterday where a reply didn't match the topic. |

Title: Re: Jet question Post by lancer on 05/26/05 at 19:43:30 It could be that we are just SPACE CADETS and are no longer able to follow a thought pattern ...in the normal manner. |
