Most likely you're thinking of the jets in the dirt bike's carburetor.
I'm assuming you mean "bike lane" ....And the answer is no, bike lanes are mainly intended for unmotorized vehicles. Scooters and mopeds with small engines might be OK, but a dirt bike is way too powerful.
That depends on what you are using it for. Obviously, if you are dirt biking, you should use a dirt bike, and otherwise use a street bike. Start out with what you are going to use the most - dirt (freestyle) or street racing.
They are quicker and more powerful and are like the Ferrari of the dirt bikes and are built for speed and racing and the Honda is like the Holden and Ford and is a basic dirt bike!
the one you maintain the most
50cc dirt bike may be available at a bike specialist store, but very unlikely. Most 50cc dirt bike are seen online for purchase only. For example eBay and Amazon.
Most vin numbers are located on the right side if the head tube.
Scott and Cannondale!

There is not a single dirt bike sportsman who is credited for inventing dirt bike tricks. A lot of dirt bike riding is freestyle.
No, it is illegal to ride a dirt bike on the street but you can ride it on a trail or dirt bike track.
It's made out of dirt obviously hence the name dirt bike.
