Throttle Response - PocketBikeForum.com

Mini · 05-29-2007, 12:21 AM

Hey everyone
I have a pocket bike 49cc engine and everytime i pull the throttle all the way the bike starts losing power and slows down when i pull it about mid way it goes faster. Does anyone know what the problem is?

Here are some pics of my bike

try adjusting the needle in the carb. it has 5 pisitions. i had that problem and i lowered the height(leaned the mixture) and that helped me. all bikes are different so you might need something different but its simple so you shouldnt have any trouble

i sort of have the same problem, but when I play with the carb pin the bike stall and stuff when I ride it. So I'm kinda lost right now. The bike runs great the Acceleration is a little off, on it's current setting.

try cleaning out your carb the needle is for mid throttle,the jet is for wot,if its stock then your jet should be right,just try cleaning the carb first, imo
