2009 versys fuel in crankcase

Hi,
I recently purchased an 09 versys with just under 7k miles. I like the bike and noticed it was dumping fuel into the crank case when ridden. Enough fuel to just fill the sight glass on a 50mile ride if the sight glass was just below full before riding.

Has anyone had this happened to them? I've been googling the internet to no avail. Seems only to be common on carberated bikes that get the floats stuck open. Found nothing on fi bikes

Thanks

Newie on me, with bikes with vacuum fuel taps the rubbers degrade over time and leak fuel into the carbs, then if a float sticks it can leak fuel into the sump.
FI bike maybe a rubber gasket in the fuel pump gone? Perhaps pull the fuel pipe off and see if the fuel pump leaks?

Found this on another forum

On a fuel injected bike the most common way for fuel to get into the crankcase would be through the evaporative system. He may have topped off the tank and overflowed the canister with raw fuel allowing it to get into the crankcase.

Are you sure it is not just the oil level slightly higher when warm? Does it smell like gas, and the problem additive over time or go back down when cool?

Pull a sample of your oil when warm and do the flame test (light it and see if it flames easily)I recommend doing when it gets a bit dark (to see flame better) and is the bike low on power, burn oil(smoke) , back fire , pop back into the intake system. And so on? Can you get pic and or video

yes im a guy.

OK guys, the bike is not "dumping fuel into the crankcase while riding", that's actually impossible. If the injectors were out of control, dumping fuel, then the bike would be running stupidly rich and there would be lots of smoke before any fuel would make it past the rings and into the crankcase, it would be barely rideable. More fuel in the cylinders and the engine would hydro lock, so no, it's not happening.

How are you measuring the oil level?
