hi all I’ve got a gv125c the large pipe looks like it is just hanging down under the bike does anyone know what it is for and should it be connected to anything
That pipe is what we call a “breather / overflow” pipe for the engine. You are correct to say that it faces the road downwards. The only job you have to do is make sure its slit is free from chain grease or road grime from time to time that’s all fella 👍
