Slip-on jetting question

[henwo1ba]

I just purchased an HMF slip-on that came with jets ranging from 135-150 and an alba adjustable needle. What jet should I use when the only thing done to my z is the slip on and the snorkle removed from the airbox? Do I even need the adjustable needle for that? Thanks

um arent jets used on what altitude youre in? Like I live in low but if i go 4 hours west to the Rapid City Black Hills, i have to use a different jet setting bc of the altitude.


There should be a chart to know what jet to use in what alt range.
