hello, i have bpr bombaradier rally 200 2007 which has a lot of gasoline in the oil sump, it is  4 stroke. Has anybody had problem like this and which can be the cause and how to fix it. i rode it today at -2 degrees celcius if it helps.

sounds like piston rings maybe it was tipped over?

If it's got a carb, the carb's float level needle/jet is probably leaking allowing the fuel level to get too high so it overflows the carb and goes into the cylinder, down past the rings and into the sump.

It is fairly common though for needle to leak very slightly and it not to be a problem during a days riding, but if you leave the tap on over night they can try to fill the sump.. So check the tap turns off.

Another thing that can cause it is if they have a vacuum operated fuel pump that plays up..
