    3 original jet sizes for 77 gs750, may change from 97.5 to 100 main??

    Seems there are three different setups for the carbs on a 77 gs750 with main jets either being 97.5, 100 or 105 and pilot jets being different as well. Slide cutaway and needle height and size are the same for 100 and 97.5 jet set up but 100 main jet is much more common.

    I have a spare set of carbs with the 100 jet and proper pilot jet, thinking of swapping out my 97.5 for the 100 and all other relative parts. Does anyone see any benefit to this. There must of been a reason it was changed and manual even lists proper parts as 100 main and 15 pilot
