To increase horsepower on a dirt bike, consider upgrading the air intake and exhaust systems to improve airflow. Tuning the carburetor or fuel injection can optimize fuel delivery for better combustion. Additionally, installing a high-performance camshaft or modifying the engine internals, such as increasing the compression ratio, can significantly boost power output. Regular maintenance and using high-quality fuels can also enhance performance.

depends if you are wearing the protection for a dirt bike that is needed
According to Dirt Bike magazine 45.5 hp.
A bore kit is a thing that goes on your muffler and increases the hp by like 30 hp
A pit bike is a very small bike that is more to like mess around with in the pits hint hint and a regular dirt bike is alot larger more for trial riding or racing.
where your throttle cable attaches to the engine notice how the lever its attached to works. The notice if there is a screw on it or a spring. If theres a spring, tighten it up for more HP. If theres a screw, tighen it for more HP.
a yz 85 because it has a big top end
Replacing the air filter with more efficient one and removing the air filter snorkel. Replacing the stock muffler with more efficient one. Re-jetting the carburetor .
Horsepower and cc(size of engine) do not relate like that. It could be a slow moving lawnmower engine of 5-6 hp or a highly tuned dirt bike engine of 30 or more hp.
For a 2-stroke dirt bike all you have to do is, buy a taller cylinder, and buy a longer crankshaft.
well it depends if it is stock or if it is HP it will go faster than stack if it is HP, but the top speed is around 50-55mph
