I picked up a 200es for cheap last summer from a local kid, changed the oil and mine started to blow oil right after...a LOT!! But my leak was coming from inside the left side over on the engine. Wasn't any where near there..
Looked like a schit job to fix and I wasn't that in love with the 200es hard tail..so I sold it for what I had into it.
Oil leaks seem to be a theme with this model??
