If, by blueprinting, you mean putting their sticker on it, almost anyone can do that. They run so good out of the box, and there is almost nothing that can be legally done. Having the carb setup professionally is probably worth it though.
I’ll echo what my dad said and just note that most of my results this year have been on out-of-the-box X30s. They are solid from the factory. But yes, carbs might be worth looking at.
I have a Manning, and another that I built. I had Comet hone / fit a new piston, and had them re-assemble my crank with a new rod kit. Aside from a very poor package job on the return trip, comet did a great job.
I re-assembled the motor after they did the crank and cylinder, and it’s dead nuts with my MMK motor at big places like NJMP.
