Title: Mikuni VM Jetting questions Post by 323dunce on 01/23/08 at 12:30:10 Hi, sorry if this has been covered to death. I'm running a 38mm Mikuni VM carb, which I know is a bit big for the Savage. I'm hoping someone has experience jetting the 38mm carb and can give me any pointers as to what ballpark I should be looking in. I'm fairly well versed in jetting but the jets it came with were way out of whack so I'm not sure if I should be thinking way under stock jets or close to stock? Thanks in advance for any help! |

Title: Re: Mikuni VM Jetting questions Post by vroom1776 on 01/23/08 at 13:08:52 I'm running a 250 main or so with my VM38 at 4k feet, cherry bomb exhaust. still a bit rich. a 25 or so on the pilot. not really tuned well, but very hard to do w/ the cherry bomb. My nedle is on the 2nd clip from the top. V |

Title: Re: Mikuni VM Jetting questions Post by 323dunce on 01/23/08 at 15:43:07 Thats funny, I was thinking about putting one of those cherry bombs on there, love that sound on a car but figured it'd be too open on the savage. What's it sound like, relative to the stock pipe and the open header? Good to know about the 250 main, that would have been quite a few steps down from stock! Got a guess what you'd run at sea level? Thanks so much man! |

Title: Re: Mikuni VM Jetting questions Post by LANCER on 01/23/08 at 17:53:30 Drop your main down to 200, the pilot to a 22.5 and leave the needle on the 2nd from the top. See how that works for you. It should get you in the ball park. |

Title: Re: Mikuni VM Jetting questions Post by vroom1776 on 01/25/08 at 11:16:39 open header sounds like a machine gun... cherry bomb will give you a headache if you stay on the throttle hard, but it sounds good. mellow, but harsh, if that makes any sense. I think that 250 is a bit rich anyway... |

Title: Re: Mikuni VM Jetting questions Post by 323dunce on 01/28/08 at 14:04:54 Thanks to everyone for the help. I'm running the 200 main with a 27.5 pilot and the needle at the top clip. Idles smooth, runs smooth, no black smoke BUT..... I can't get it to start without covering the open end of the carb with my fingers to choke off air. The choke lever on the VM38 isn't helping. What's my next step? Thanks in advance! |
