Carb jetting help

[Eddie Campbell]

Hello first time posting on here but I am kinda stumped getting my new carb dialed in. Had OEM Mikuni carb Main jet #260 idle jet 32.5 and so forth. So i got the Mikuni VM26-8074 changed main jet from #190 to #260, Idle jet from #60 to #32.5 left needle jet and needle which came in it. How do i figure which needle jet and needle to use on 8074 carb that matches my OEM carb? Thank you

Where did you get the carb from? Can’t you just use those parts from your old carb ?
