I mean it's not crazy, but i'd warn against taking and applying advice directly from a 2 stroke guru if they're not a moped guru.

Specifically dirt bike guys, alot of the same stuff definitely applies, but alot doesnt, one of the big ones being the lack of gears, which can change alot about where you're running and where/how wide you wanna make power. at least you're variated though, so as long as you know what youre doing there you can take advantage of peakier high RPM power with a loss at low RPM.

for example, you look at an RM 80 and theyre running 28mm carbs, some of the competition folks run up to 32 and over. That's like racing dirtbike shit tho, those things make at least twice the power your kit does. and theyre spinning up to 14k, not to mention being slightly bigger too

the other thing to consider about carbs, and its obvious but also easy to overlook is that youre reading a diameter but the flow's gonna be proportional to the xsectional area, essentiall it scales with r^2. so like from a 18 to a 28 is 1.5x diameter but effectively 2.5x the size... that also affects your velocity. you've got a flow rate based on your engine's volume (draw per revolution) and RPM. so for the same RPM you have to have the same flow and so your velocity's necessarily gotta be smaller which can hurt the mixing of the charge and response. Flat slide might be better here also.

or the tl:dr w less theory, similar sized high performing engines can use that size range of carbs, but you might be overcarbed for the limitations of the cylinder and engine, and see worse performance in terms of responsiveness and low end torque.

and of course much worse gas mileage.
