It starts fine, but i need to constantly throttle , up and down for it for it to move. Acts like it running out of gas. I installed new carb, new fuel filter, new fuel, adjusted valves, replace ignition and coll modules. replace vacuum lines., replaced air filter. tested petcock and replaced petcock with direct fuel line , . Only 576 miles on the trike. new spark plug did not make any difference. what is left to do? Here is a short video of the engine hesitating . youtu.be/6z7qU5rdxS8thanks |

Have you tried placing blocks under the axle to elevate the rear wheels . . to determine if any difference in throttle response? Variator weights may not be properly oriented in the ramps? If sparkplug is reading rich . . petcock diaphragm may be deficient? |

To accurately diagnose problems follow the troubleshooting guide in the service manual to the letter. Guessing and shotgunning a scoot with new parts is not the way to fix them.
On the other hand, have you checked and adjusted the rear brake?
