I have been working on this 2000 banshee I bought with problems, needle valve in one of the carbs was bad, motor leaking at a few seals, re-doing entire brake system, and now I'm finally at a problem I'm not sure what it is. There are 2 nuts on the bottom of the motor that appear to leak when the motor is warm. A mechanic told me it sounds like the oil in the gas is separating and leaking from there, I rode the bike for an entire day and checked the oil in the motor and it seemed to be full still
