hi all, just bought a yamaha 600s diversion N reg, so believe it's a 95 model. the bike is in superb condition and has only done a genuine 2800 miles from new. are there and geeks out there that can help me with an issue that has become very fustrating. the fuel overflow pipe that is split over the 4 carbs constantly leaks fuel over night. this does stop after a period of driving/ warmed up. i understand it's a vaccum system, so could it be a vacum pipe issue. the also appears to be a small square box type thing coming off the tank, have no idea what this is but that also leaks. the fuel system/ carbs had spent a month or so in a sonic bath so all clean etc. any help welcome. cheers all
