The ghetto wheels are great, but many people are very disappointed in their service. Might take a year to get, no joke.

God damn son! This makes my bike seem so slow 😂 what's the secret to getting some more power. I've got a pk80 and I don't feel like it could even pull taller gearing than the 44 that's on it.
This is a fully build CNC case Athena 80cc, so ya its gonna be faster than a china doll. But chinas can be fast, just gotta put the work in. Ill be doing a full walk around video of the bike soon keep an eye out for it, it will have all the details.
Paul D.B , use a timing degree wheel and grind some proper port timing as well as proper port shape then you've got to get the carburetor jetted and tune correctly oh yes oh yes and let's not forget a proper exhaust pipe. A CNC case don't make more power it just makes them look cool and cool points don't make HP just being honest here. Any Chinese motor of equal displacement if ported properly and jetted properly capable of doing this and more. But yes it runs good, She rips Aey!
A proper expansion chamber will add at least 1hp on it's own. Aside from that, you can port the cylinder (allows higher max RPM), and add a reed valve with a windowed piston. Adding a boost port or a 3rd transfer port in addition to the reed valve will give you even more power

im afraid of 2 strokes reving high but in fact 4 strokes at high rpm are more dangerous the piston can catch valves and you end up crashing bad
Transmission
Valves will launch off the cam and hang open as the piston comes back and bends it. Stiffer springs solve that.
The piston coming in contact with the valves has virtually nothing to do with you "crashing bad" 😂😂😂
Jeez that 40-57mph band sounds scary
ya that kx85 pipe hit is no joke. Even a cr80 or scooter pipe is so much smoother.
