Have a 02 SXR 600 sitting in a shop. There is oil in the coolant. Been a long time since I worked on these so what do I look for first?

The oil has no direct way to the coolant other then through the head which it will be mixed with gas. Has to be a head gasket. Easy enough to do a leak down or just take head off and inspect.
Long shot.... water pump / oil pump drive........

Seal behind water pump, the seal is letting oil from the gear drive area into the coolant system.
I would suspect its the water pump seal. Pressurized each cylinder and no bubbles in the coolant
