i will put in on polini 70cc aluminum evolution, with LV exhaust, satge 6 intake, stage 6 variator clutch and bell

i want a racing scoot and stunts...

Both carbs should work. I don't have experience with flat slides, but lots of ppl prefer them on 2Ts. One downside I hear is that they are or can be harder to tune.

I think you should reconsider that LV exhaust. You're looking at a cylinder that probably wants to rev 12,000-14,000RPM. Not sure, I know Polini made different versions of the Evo and I don't really follow the high end stuff. At any rate, it's gonna rev well beyond what that LV will be comfortable with. I think even the Handmade 70 is only something like 11,000 RPM? Polini makes some exhausts that work with their Evo kits and a lot of ppl like Yasuni C-series pipes. There are more out there, but those are a couple of ideas.

I worked on a "mismatched" engine like that. With a "mid-race" pipe and a "sport" cylinder.
It took all the low-end out of that jug but still pulls hard up top.
