I have a problem that I'm looking for some suggestions with. I have a 1985 Yamaha XJ700 it had a 4 cylinder engine with 4 carbs. I am the original owner and the bike only has 8000 miles on it. It is leaking fuel all over the floor. It has done this twice before but both of those time it was when I needed to move it in the dead of winter and it was freezing cold so I just figured something was forzen open, this time however it is in warm weather. The fuel overflows into the breatherbox and then when it get full enough the fuel runs into the vent hole that goes into the crankcase. Both of the times it happened before I made sure I changed the oil before running the bike. I'm not an engine expert by any means but I am trying to find out what someone who does know engines for their thoughts on what could be getting stuck open that would allow fuel to run out like this. Also is this anything I could try doing myself before taking it the dealer to have it looked at. I have no problem with taking it somewhere but unfortunately the shops near me do not have a great reputation and I thought I would ask for some suggestions first.
