    SBN 44 Carb Help

    I have a brand new MIKUNI SBN 44 carb for my 750sx stand up ski since its a good upgrade and ill be keeping the ski for a while. The engine is stock and right now I have a 120L and a 150H speed jet in the carb. I need to know what to set the h and l speed screws at as well. Is 2 turns out on both a good starting point??? I dont know much with jetting so iof anyone has this carb, I need help!!

    Is that what it takes to get it to run? Usually if you have to go more than two turns out you need to go with different size jets. When I put on a 44 its 1.25 turn on the L .75 on the H and tune from there.
