Hi, having bought a 1991 1200 Trophy as a none runner , the tank being loosely fitted I got the bike running by cleaning the contacts on starter solenoid, the carb rubbers were split so have changed them all and air box etc.My question, the tank s pipes were fitted as follows, one petrol pipe to left of frame and left of carbs, one running under frame to right hand side of carbs, small pipe from back of tap to third carb top and the pipe at the very back of tank was connected to the fourth carb top. I thought this was an overflow pipe which should go to rear and three of the four carb should have blanks. If someone could verify routing etc I'd appreciate it Many thanks John
