    Default 1983 V65 Magna Rejetting Question

    I have a V65 with the 4:1 Kerker header and exhaust. IT currently has the factory 140 Jets and appears to be a bit lean. Does anyone know if there was a recommended rejetting size for this setup?

    There would only be such a jet setting for sea-level, if that's alright with you. Or you could just apply the simple 3 - 6 % formula, where you'd multiply the stock jet, 140 in this case, by 1.03 - 1.06.

    And if you're after making her the best she can be, simple use Factory Pro's CV carb tuning procedure. It lays it all out in a step by step DIY.
