You are going to have to get a jet kit with a wide range of sizes.  I find that running a jet so large that it bogs out rich is a good starting point - then step down until it is able to accelerate without bogging.  This way you will not run too lean, and seizing it.

Assuming that you start out with no hesitations or dead spots in your acceleration by having your springs and rollers set up properly.   Poor transmission tuning can mimic poor carb tuning and vice-versa.
