Title: Main Jet Types Post by marlin72 on 07/25/06 at 18:49:39 I am getting my exhaust pipe mod made for my sporty muffler. I am going to buy some mikuni main jets before I start the carb mod. Plan to buy 147.5, 150, 152.5 and 155. Which ones do you buy,ie hex, small round or large round. I want buy all the parts before starting this job. Marlin72 |
Title: Re: Main Jet Types Post by Ed_L. on 07/25/06 at 19:02:27 If I remember right the carb in stock condition has the large round main jet. When I rejetted up to 152.5 I used a small round main jet with no problems. I believe they are interchangable just don't loose the little brass washer that goes between the jet and carb body when rejetting. |

There is an idle mixture adjustment screw that adjusts the pilot circuit. You should only increase/decrease the jet itself if you cannot adjust it sufficiently with the screw. |
Title: Re: Main Jet Types Post by PA KID on 07/26/06 at 14:07:30 Yes you can adjust the pilot circuit by turning out the screw,and if it dosent give the desired effect.Just pull the carb off again and change the pilot jet. |

Or just drop the float bowl while leaving the carb in place. Worked for me. Have an EZ-out available though. Sometimes the pilot jet is stuck and strips easily. |
Title: Re: Main Jet Types Post by marlin72 on 07/27/06 at 18:29:39 Thanks for the help. I am use to dealing with diesel boat engines,thus no carburetor. This is a new venture for me I'll take it one step at a time. Many thanks to all of you folks. |
