Any governing on these will be done through restrictions on the carb. You can try increasing the size of the jets. or maybe get some increase by opening the Jet screws on the carb. You can also decrease the amount of oil in the fuel oil mix but this will greatly increase the risk of killing the engine. never go beyond 100 to1 mix.You can also get a little increase in speed by decreasing drag . make sure tires are up to proper pressure and take any drag out of the brake by adjusting them and greasing wheel bearings so everything runs smooth. Keep your chain snug so there's not slop. Just a few ideas Hope this helps
