after a few minutes of reading, most Big Twin's from 1986-2000 used a #42 as the stock pilot jet, with 2000 models using a #45. I'm not too familiar with jet sizes..but if that helps you out at all, there you go

i think it was a 42 slow and a 170 main. from what i hear it kinda depends on where, when and what time the bike was purchased as to what they put in the main. weird... i know
