70mph, are you nuts? In a kart, that's gonna feel like about 200!

You're also going to need a stronger conrod & valve springs. I would also suggest you get a CVT if you want any chance of reaching that kind of speed

a cvt would get shred up going that fast with high RPM (at least a comet 30 series would)

it would take a lot of engine mods, expensive clutch, and going that fast you would want high performance steering setups, a strong frame because your life depends on it, balanced slick tires, heavy duty brakes, etc.

i would return the predator and look into 125cc race karts if i was you

Check out Stage 4 Kit from this people (LINK). This kit is suppose to get the predation over 20HP but it will also cost you $$$.

Keep in mind if you want to get that speed, aside from all the engine things you will need 2 things: 1) A suitable frame to handle the speed and power 2) A place to ride it.
