Jet it for best MPH at the track.

If you start to mess with big spreads in jetting front to rear, you run the risk of leaning out some cylinders.

If you do pull jet out of the front, the best method to get that area back is to increase the power valve channel restrictor size.

I think I will just set the 850 carb back to stocks specs . couple jets sizes smaller on each end. that will work.
