There's an adjustment nut on the hand grip for the throttle cable. Back it out to make the throttle tighter, and screw it in for looser.

There is a black screw behind the carburetor, if you turn it clockwise while it is idling you will hear the rpm's drop.

I think your asking how to restrict the speed of a 50cc. mini bike, you can do this with the throttle cable, adjust the cable to only open the carburetor 1/2 (half) way. If you mean how to UN-restrict the bike, the usual way is with a throttle stop, simply loosen the cinch nut and back off the stop until you achieve full throttle, and retighten the cinch nut.
the rear tire tube on a 70cc baja dirt bike is 3.0-12

the baja warrior goes about 30 -40 haha, 30-40, yeah right. stock this bike goes 20, you adjust the governor open the air screw a little tighten the springs, open up throttle screw, and take off muffler, and you can get up to 35 tops. you swap some gears and you can adjust power and top speed, i got mine up to fifty by bypassing the middle sprockets and making one chain from clutch to wheel. took a long time to reach 50 but it did it.
