Thank you! I really appreciate your detailed response. I wasn't even thinking about it having air in the system from being filled improperly! I will start it up tomorrow and get it up to temp and see if I can confirm and mixing and if the coolant level remains stable. I also did not know that oil could become milky...

Correct, I am familiar with a little smoke from 2 strokes but this seemed more dense, not as bad as a car with a blown head gasket but more than what I would consider normal.

TBF I didnt run it long enough to see if I'm losing coolant, basically as soon as I saw the bubbling in the rad and what looked like the crankcase oil getting milky I shut her down to limit any damage I might do. I assume if air can get into the coolant system coolant can get out too?

I was kinda thinking the same thing something deff not right about bubbling in the rads

Yes the water appeared to be turning cloudy as it bubbled and the bike was not up to temp yet I only ran it for a minute or two tops so I don't think it was even warm enough to boil. The bubbling deff increased when I blipped the throttle seemingly correlated to the rpm. I would compare the amount...

Trying not to stress it too much till I hear from you guys with experience. Dont really know anyone that knows anything about dirt bikes and the only info I can seem to find is mainly referring to street bikes and people running water and water wetter.
