Can you explain why when main pipe from tank is disconnected, the tank only empties at a drip? 2 litres taken hours.....
It so happens I have the same problem with Yam TRX850.....bought a jig to stand the carbs on to check the float heights.  |
If you pull the fuel pipe,not the vacuum pipe, off the Fuel pump does fuel flow ? There should be none when the engine is stopped as there's no partial vacuum to open the Valve in the Petcock.You may have a faulty Petcock if there's been fuel leaking through.
You can buy service kits but....
I fitted a new cheap Petcock,

However they some with a wrong larger spigot pipe so I use some larger diameter fuel tube and an in-line fuel filter to compensate,
