950 Ultra XP tuning on 500"

The HP has 2 power valves..


Ok, the square jetting makes sense. Without seeing the emulsion and bleed packages I can't say for sure but to me, 92's seem way big to me. I'd also want to know what size the power valve channel restrictors are.

Remember, you cruise on the mains. With staged linkage you only cruise on the primary jets. So those 92's sound HUGE to me. But without seeing the rest of it, it's hard to say.
