How fast can your 80cc really go?

Hit and held 46 with a shift kit, slant motor, NGK plug, and no other mods. This was confirmed on speedo and GPS 
Hoping for 50 with an expansion pipe, etc.

i hit about 45~ish on my red beach cruiser, it has a 36T sprocket,and piston skirts trimmed, and a little mod i did to the stock pipe
I got up to 50 a couple of times. 80cc schwinn beach cruiser ngk plug/plugwire, 1 gear all stock. You have to push it passed the point it sounds like its going to explode and have a wide straightaway, mine has a 55 mph speed limit, so if u dont go fast you`ll get run over. Its hit and miss 30% the time it breaks down afterwards all vibration issues. Ive been told its leaky and air is getting in and im running rich. but it hasnt blown up yet.
I don't believe 80cc HT cranks can spin at 13000rpm without blowing up. Or 10000rpm. Even perfectly balanced ones. Most will vibrate to pieces at half that.You don't believe that mine beat 58kph?
And if your tire is 2 meters diameter like you say the torque is so low it's unlikely you can go 2kph.The tire have 2040mm
47.50 IS FAST... Geared is the way longer streaches could get more three stages extra parts everywhere good fun

thats like 36-37mph which is around the top speeds(not cruising speeds) for these engines with a stock 44t,but usually seen more with a 36t. some of the engines will have a lower top speed and also depends on the weight/size of bike and weight of rider and also the sprocket size.
the max rpms for these engines are usually between 4500rpms-8000rpms.
i usually cruise around 25-28mph and i can get the bike upto 35mph but i do not ride for a long time at those speeds as i dont want the bike coming apart or exploding.

I don't have but a 48cc Dax kit on my bike. Stock all the way. It was going over 90 mph! in the back of one of my bros pickup truck!
