    Hello for a few months i own a four stroke engine everything is fine with the engine but i'm getting weak i am about 110 kg and picking up speed and starting from a place it's hard to wonder if it could somehow increase its power or torque?

    The usual formula for a four stroke is bigger carb, bigger valves, bigger cam, less restrictive exhaust. You did not say what brand or size thumper you have. The only one that you can find a bigger cam and valves for is the 212cc industrial motors like the Harbor Freight version. The cam and valves make the biggest difference.
