Hi again.Took the fuel pump out,took it apart haven't noticed anything special although i'm not the expert.pump is run by vaccum not electric one.took the fuel hose which goes from pump to the fuel hose joint which is in the middle of 4 carbs.And noticed the plastic kind of plug,plugged in to the fuel hose joint,couldn't see how fuel would go through that plug so took it out.got bike together,started still same problem,not firing,just starter sound.so is it time for carbs to be cleaned?don't think its difficult job but will have to do it on my drive:)
