Milk-iness on dipstick?

[MissionMtnMax]

It's a '99 MM 700 that I recently purchased - I've put about 150 miles on it. Pulled drive dipstick tonite - milky on top....am I leaking from heads or just maybe from sitting out with no cover or.....??? Thanks in advance.

sounds like u are looking at the chaincase oil (not connected to motor so no prob there). just drain oil and start fresh again. check chain tension bolt while your there, it should be hand tight w(with secondary turned forward to pick up slack in chain). tighten jam nut and your good to go
