Yesterday it rained, so I took advantage of the primo riding conditions and went for a ride, there were lots of puddles, thinking nothing of it since I've ran in the rain before without issue. today I unloaded my bike, noticing it was a bit hard to start, rolled it into the shop, discovered milky oil, popped the radiator cap, coolant level is fine, flushed it, put a new oil filter in it and filled it. now my concern is, would there be anyway the water could have worked its way into the engine? (the engine side, not the tranny, it was fine) breather tube of some sort? or should I be looking for an actual engine problem?
