Title: '97 main jet size? Post by Banger on 06/21/06 at 04:51:11 Hey all. I'm going to get a K&N drop-in and possibly do the snorkelectomy in the next week or two. I know this will necessitate a main jet upsizing, too. So what's my stock size? I'm thinking one denomination (2.5) above is a good place to start. I see many of you running 152.5. I trust this works pretty well regardless of year? Regards, Banger ======= |

Title: Re: '97 main jet size? Post by Reelthing on 06/21/06 at 06:26:16 stock on the '97 is a 145 main so depending on your altitude it takes a 147.5 or a 150 to get the engine where it should be with no other changes, so add a free flow exhaust add 1 jet size, add a free flow intake add 1 more - so a 152.5 would be a good start if your doing both but I'd have a 155 in my pocket as well. have you work over the mixture and mid range yet via needle jet white spacer (cut down, or replace with washers, or needle with c-clip slots) ? more important than the main jet to get correct unless you run WOT all the time. |

Title: Re: '97 main jet size? Post by Banger on 06/21/06 at 08:55:23 I did the white spacer removal. Cut it out completely. I seem to remember a time when that was preferred among Savage tinkerers instead of filing or doing some sort of half-spacer mod. Presently, the bike idles a bit rich. Starts regularly without choke on warm mornings. I run almost all my miles at 65 mph, though, thus the thinking I should richen up. Also figured with my new exhaust (well, it came off a 1975 Honda CB500T, so it's got little in the way of baffling left after all those years) and the upcoming K&N and snorkelectomy, it was time to figure out what to do. So 152.5, but keep a 155 in mind? Regards, Banger ====== |

Title: Re: '97 main jet size? Post by Banger on 06/21/06 at 11:50:50 It was stock off the CB500T circa 1975 and 1976. Regards, Banger ======= |

Title: Re: '97 main jet size? Post by Savage_Rob on 06/21/06 at 12:34:25 My 98 ran just the same with the 152.5 as she did with the 155, except the 152.5 got better mileage. That was using the MAC muffler and a K&N filter (direct swap for stock, not pod) and a snorkelectomy. |

Okay, what the heck do people mean when they say a snorkelectomy and a direct swap KN? Seems to me snorkelectomy means removing the snorkel and bolting a pod right onto the carb... sounds mutually exclusive. |

Nope, the snorkelectomy is the removal of the snorkel whether you do anything to your air filter or not. It will increase airflow. I did this and replaced my stock filter with a K&N direct-swap right in the airbox... no pod at all. The direct-swap is just that. It's a K&N filter that replaces the stock filter but is reusable oiled cotton instead of paper. If you use a pod, there is no purpose in doing the snorkelectomy. |

Title: Re: '97 main jet size? Post by Savage_Rob on 06/21/06 at 12:46:00 I just pulled the seat off and grabbed the snorkel with a pair of pliers and pulled it out. |
