I've had this with a few scooters over the years and i've never really worked out what it is... You start the bike cold, accelerate off and it goes like normal nice and nippy or at least as nippy as a 50cc can be. But once its hot it bogs down especially accelerating from a stop at the lights. The revs dont rev up as high and it runs much slower. Any idea what this is? Clutch too hot? Rollers? It's really annoying.
