    '93 SL750 help please

    Anybody happen to know the stock carb settings? I can only find settings back to '95 and that shows center carb high speed only 3/8 turn out??? Also there was no restrictor pill on this one but the return lines only have small openings out of the carbs, they're not fully open. Do I need a restrictor? Thanks for any help.

    Yes, you absolutely need a restrictor in the return line.

    OEM settings for the carbs:
    Low Speed = 1/2 turn

    HS MAG = 7/8
    HS CEN = 1/2
    HS PTO = 5/8

    Main Jet #77.5
    Low Jet #72.5

    Idle RPM 1250 +/- 50

    Pop-Off = 10-18 PSI

    Finally, if you have not already upgraded to a 3-outlet fuel pump do so now while you're tooling with the carbs. John Zigler has the complete kit for a very good price.

    Thanks. I just rebuilt the carbs, replaced some fuel lines (no restrictor found) removed the autocock, and upgraded to the triple outlet pump, not to mention a new starter, and gaskets. Do you happen to know the hole size for the restrictor? I can just drill a holley jet or something i imagine.

    After a little online research, it appears a Mikuni 90 is about a #63 drill bit, or a little bigger than 1/32". So I'll try that and see what happens.

    Honestly, the 93 didn't come with the restrictor installed, but there's no problem with putting one in.
