How to Install Pocket Rocket Boost

How to install a boost system on your pocket rocket.

This is a great way to give your bike a little pick up. “With the simple instillation of a Boost Bottle kit, your bike will be leaving the others in the dust”. I have head this before but if you are dealing with a 49cc engine this is not all that true. The boost will if installed and sized properly give you a gain in power.

How does a boost work?

Myth: There is a mixture substance in the bottle like a nitrous system in a car.

Fact: The whole system works off of a back pressure. The boost bottle connects to the carb via a modified manifold. When the engine runs the boost can fills with air creating back pressure causing a bunch of physic’s leading to a supercharge type of effect at the end you get some more power.

The key here is the, size of the bottle make sure you get the right size bottle that goes with your engine size. Double bottle is not necessarily better then single in this case.

1. Manually empty fuel tank completely.

2. Shut fuel value off on carb and disconnect the fuel line from the carb.

3. Locate the throttle cable connected to carb. disconnect throttle cable from the carb by loosening the screw and spring holding the throttle cable in place.

4. Unscrew screws attaching the air box/air filter to the carb to remove the air box/air filter. Keep it clean sure to not get any dirt into carb.

5. Remove two long screws holding carb to manifold. Be sure to not lose the gasket between carb and manifold, you will be needed again.

6.Remove the manifold by unscrewing the four screws securing the manifold to the engine. Once again, be careful with the gasket between the manifold and engine. Put the removed manifold aside.

7. Install the brass valve on the new manifold, and place old manifold gasket on new manifold so the carb.

8. To install the manifold, carefully place it against the opening in the engine, ensuring the brass valve(s) are facing down. There is only one way the manifold will go on, so don’t force it. The opening for the carb should be parallel with the ground. Replace the 4 screws

9. Connect the hose to the manifold by pushing the hose over the brass valve on the manifold. Make sure to push the hose all the way up the valve.

10. Reinstall the carb by aliening the body of the carb (opening) with the opening on the manifold. The fuel bowl of the carb should be towards the ground. Replace the two long screws that were removed before.

11. Reconnect the throttle cable to the carb by tightening the spring and screw.

12. Reconnect the fuel line to the carb by pushing it over the fuel valve on the carb. It is a good idea to put a zip tie around the fuel line to secure it to the carb to avoid fuel leaks.

13. Reinstall the air box/ air filter to the carb by holding the air box with the openings towards the ground and aligning the air box screw holes with the threaded holes on the carb. Replace the two screws.

14. Attach to boost bottle by pushing hose over the brass valve on the boost bottles.

15. Use zip ties to mount the boost bottle(s) to the frame of the bike. The bottle must be mounted at a level above the carb to function properly. Recheck all screws to ensure all components are tight.

16. Fill bike with fuel and start bike up to check to make sure throttle works properly and there are no fuel leaks.

17. Now you are ready to ride.
