did you pull your plugs yet? something's gotta be massively wrong to be blowing through that much gas that fast.

Time to explore correct petcock function. start by making sure no gas flows from petcock when in "on" or "res" spot when engine is off.

was it the #2 plug(second from the left ) that was wet?? My 650L had a torn petcock diaphragm and was sucking gas through the vacuum hose in to the number 2 carb and making the plug in that cylinder wet. It was also putting some liquid substance out the left side pipe.

That's exactly what my 650 did last summer!

i think it was the second if not it was the first one on left

check the petcock first thing. Odds are the diaphragm has a hole in it allowing gas to go through the vacuum hose in that #2 carb
