my gilera runner sp50 has the same problem at the moment i cant find out what the problem is

it means its weak there is a fuel shortage somehow,try this take the slide out of the top of the carb and take the cable out of the slide then pull the needle out of the slide you will see a small circlip on it and about 4 slots move the circlip to the lowest slot nearest the pointed end of the needle and out it back in a try it,also make sure the air filter is on properly and it has not leaks or holes drilled in the air box the mixture screw on the carb should be set to 2.5 turns out on this model.

check air box is nice and tight. make sure there is no air gettin any where it should be. When did this problem start? After you worked on bike or suddenly. Is the bike standard or does it have an fancy bits on it?
