You could try remapping your ecu. I would get it done professionally though. You wouldn't want to change the wrong settings and damage your engine.
Synthetic oil does not improve power ratings, however it does extend the life of the engine and considerably reduces the rate of sludge buildup.
There are many ways to improve the horsepower output in engines. Bolt on products such as superchargers, ignition coils, and headers are popular options but can be expensive. Cheaper things you can do to obtain more horsepower are: installing a high flow air filter performance spark plugs and wires installing a Vornado using a higher power octane booster in the gas tank
Install a K&N Air Filter (Cone version)
== == It came with 245hp from the factory, but you can improve it with headers and a good intake, ignition upgrades.
K&N filters improve airflow to the engine and slightly increase horsepower. They also give the engine a deeper tone when you get hard on the throttle. Horsepower gains are from 5-10 HP depending on the car.
you will get 50 mpg more and at least 200 more horsepower
Install a computer chip upgrade to improve fuel injection and ignition output. This is the most "efficient" way to add 50 horsepower. The quick and dirty way to add more horsepower is nitrous oxide. Putting the motor on a single-stage NOS bottle will raise horsepower, but threaten the viability of the engine.
A long lasting car purifier is used to improve the performance of a car, increase gas mileage, improve towing power and boost horsepower by increasing the amount of air in the engine.
You can start with a cold air intake, headers, exhaust, and tune. If you want even more, then turbo or supercharge the car.

To improve the horsepower on a KX 85, you can start by upgrading the exhaust system to a high-performance pipe and silencer, which enhances exhaust flow. Additionally, tuning the carburetor for optimal fuel-air mixture and considering a high-performance air filter can increase power. Finally, ensuring the engine is well-maintained, with fresh oil and properly adjusted valves, can also contribute to improved performance.
Watt was competing with horse power for business. He pitched his new steam engine in terms of the number of horses it could replace.
