RPS Hawk 250X with Nibbi carburetor upgrade.

This is my 3rd test run on this Hawk X. Lower Alabama at about 94 degrees and high humidity. 1st run was with a #115 Main and was too rich. we did a de-cat and it ran even richer. Jetted to a #110 and that seemed to do the trick. Thanks for watching.

hey man i got a nibbi carb and it came with a new intake manifold but it dosent have a vacuum line at the top like the old one does i just was wondering does your hawk have a vacuum line to the intake manifold if so with the pe28 did you have to change your intake manifolds or could you use the original one? i have the pe30 and it dosent match up with the original intake manifold so i have to use the new one wich dosent have the hole for the vacuum line could i just plug the line ?
