Not burning coolant or anything else that I can tell, but I get some constant smoke out the back. There's only like 1 hour max of run time on it so far, and I'm just wondering if it's somewhat normal for a brand new motor to smoke some early in the break in.

 

Yes.

 

Thanks!

 

its proabably just the oil/residue and other stuff on the pistons/cylinder walls etc.. from being assembled.
