I actually had that same problem when (very rarely) I would break into 6th gear... This was however before my recent rebuild so I couldnt apply it to my current setup but... Anyway, Im still not sure if my jetting was ever right because of how it used to slug so hard in sixth gear.... My condition (knowing what I know now) seemed to be more of a rich one though, like it would just load up and bog. I would be grabbing handfulls of clutch trying to reach powerband with no luck. This all used to happen only when I went to Paragon sisnce they had a sweet long striaght road, with my new setup I havent reached 6th once.. But Im sure its to fat @ the main Jet right now anyway... :wallbash: Tuning is harsh sometimes man, no matter how you do it, Mr. Fusion kit Data or plug Chops :biggrin:
