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.

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.

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.

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.

Either large or small jets will work. Tried them both- no difference. ;D
