    1200 Keihin Jet Help

    I need help… I bought 3 carb rebuild kits to rebuild my Keihin40mm carbs for my X45. I swapped carbs from the “POS” Bings to Keihin 40mm thatI bought form TXPro1200 4 or 5 years ago. When I took the carbs apart, I didn’trecord the High/Low jets sizes with their respective positions. I have twodifferent jets (42 & 65) that will fit in the same position. I don’t rememberwhere each of the 42 and 65 jets goes.
    Here’s a picture of the jet locations.
