i noticed today that there is a black rubber vacuum hose looking thing hanging down from under my bike... i got under it and looked around and it doesnt appaer that there are any connections that it should hook up to... so i guess my question is, are there any black vacuum looking hoses on a ninja 250 that dont connect to anything? iwas thinking it may be a drip hose or seomthing like that. bike still runs great. lemme know what you guys think. its right near the center stand under the bike.
