The first, and most important suggestion would be to run some type of wideband O2.

Next, keep in mind that the main jet and high speed bleed are a combination. The High speed air bleed can have a greater effect on the fuel curve at WOT than the main jet size can. This depends largely on engine size. Smaller engines = larger high speed air bleed...Larger engines = smaller high speed air bleed.

With that in mind I would run a high speed air bleed no larger, in any circumstance on a 528 cu. in. than .028"

93 to 95 main jet seems to be a norm for a 1050 Dominator.

I would start out square as your description sounds like an all out, or at least more than a street strip race deal. After your WOT is sorted, definatly run a power valve in the primary side and take out the main jet amount ot correspond to the power valve channel restrictor size.

The basic math for a power valve is ...
primary main jet surface area + power valve channel restrictor area = secondary main jet surface area.

This would be a brief description on Wide Open Throttle tuning for a Dominator.

idle,transition ,and acceleration pump tuning are all thats left to do.

The last suggestion ( perhaps this should have been the first) would be not to run it out of the box.
