Mikuni jets are more, but not that much more and then you have them for a lifetime. It's good you have the capability of measuring them but most people 99.9% do not so I feel vindicated in choosing to advise against them. Plus their chinesium brass grade is highly likely to be poor which could lead to more problems.
Imagine being lean and going up two sizes and ending up more lean! Unbelievable. It usually pays to spend the money upfront on the quality parts. At my work I always see customers trying to save money with cheaper parts or cheaper labor and they always end up paying way more in the end and that's not including their time.
