    Hi,

    piaggio nrg power dd stock with leovince tt pipe ,
    runs good when started cold , but after 5 min ride it becomes slugish doesnt pick up speed and slow acceleration , if you leave it for 5mins and ride it again it's good again and it repeats , it had cracked manifold i changed it started to idle better but still same problem , also it boggs at full throttle like it's starving fuel , also it drinks fuel very fast , i put full tank in it and after a week its empty after like 80km , main jet is 65 , tried to unplug choke runs almost the same just doesnt idle.
    Please help

    You've got to rejet the carb to suit the pipe.

    It is rejeted , it has a coco spark plug , could it be low compression ? Because when i put my finger in the spark plug hole , it doesn't push off only a little lift , kickstart also is very easy to press, it acts strange when started let it warm a little for a few minutes and ride it it rides great with good pull after like 3-5 minutes it looses power and doesn't pull accelerates very slow , going uphill is imposible , or could it be something with belt or clutch related?
